Just for clarification, the ECU is limited to 22 psi. 3.5 bar gets you a 1 psi increase of visibility without scaling. Nothing more, nothing less. So it doesn't really matter if you have stock or 3.5 bar with OTS maps. The reason we can see more with MHD custom tunes is the fact that we scale the sensor from 10 psi at a 50% rate to achieve 36 psi max and the conversion of the PSI displayed is done internally within MHD. Now, looking at the boost gauge, without seeing throttle angle, we cannot determine that actual boost as throttle closure will cause boost pressure in the charge pipe to spike. Unless the boost gauge is located in the intake manifold, we will not have an accurate boost reading as the tmap sensor in the manifold is only a 1.5 bar sensor and it cannot be changed due to the fact it's there for calibration. So knowing throttle angle at WOT with boost spiking to 27 psi brings up some questions also for guys that use AIC port injection as the amount of fuel sprayed would be more, even if throttle was closed and the actual boost in the manifold was only 21 psi. This would cause the car to run extremely rich and could protentional cause a misfire, and large fireballs shooting from the exhaust which is another side effect. A good reason to upgrade to the ReFlex as the CAN integration helps prevent injector overrun off throttle with charge pipe boost spikes. So, v5 e40 does a lot of things to pull out the stops and make the car as quick as possible. I agree it's one of the quicker maps we have done over the years, but if you have throttle closure, you are taking the risk of turbo surge which can damage the turbos. Sorry for the ramble, head is not so clear today as I'm still recovering from covid.
I am not worthy 🙌🏻
I had totally forgotten about the scaling. Man you are a world of information. Thanks for the clarification.
Why does the ecu close the throttle? Can t you guys go up with the „load“ of the ecu it is not limited to 22psi?
@@alexandrumardare828 Overboost safety, and No... 22 psi is a hard limit within the ECU logic.
@@wedgeperformance2816 I ve seen a lot of throttle closure on ots maps like the stage 2. Is it possible to regulate down the boost by wgdc only, not going over the target boost pressure so no throttle closure happens? Does the mhd+ wgdc work differently?
Swap Depot's E90 made 580WHP on that V5 E40 OTS map with 17ts and at the time did have the 2.5 bar sensor! We literally broke our heads the following 2 weeks trying to figure how he made so much power. Also I believe Ken desensitized the knock tables on that map which made the timing corrections not seem as bad.
The more you know!
Hey yeah exactly! After seeing you guys put those numbers down we figured we would go for it with a similar setup. We also couldn’t believe the times we ran then Andrew and Ken commented and explained the conditions with overboosting etc.
I’ve been running the V5 E40 map with stock turbos and stock 2.5 bar sensor for awhile now and it’s fun! That’s what I went drifting with back in January too, the biggest problems I’m having is with the left axle..
@@ScubaSteveArkinstall What's happening with the Axel? Is it making any weird vibrations or anything? Or just a wheel bearing? I've been hunting a very small weird vibration in my car for a year now and I can't figure it out.
No it was working fine, I just put it in back in January as a brand new aftermarket replacement to my original axle that broke the cages, and on a fairly hard 1st to 2nd gear change the shaft just cleaned snapped!
Massive thanks to Gary and Christian for putting this car together and sorting me out with the footage!
The pleasure is ours!
Thanks Andrew l! Great video and thanks to you and Ken for helping out with the explanation and sorting out what was going on!!
Couple more details:
- 7.5” stepped “race” EBay intercooler (same as VRSF I suppose)
- 34F New England (I mean Mexico) temps :)
- Very high DA
- 2nd gear launch (this car launches better in 2nd)
- Closer to E45 mix
Car is still running great and we run the V10 Stage 2+ OTS with stock t-map day to day (I know we shouldn’t). I think this prevents the throttle closures as well and protects the turbos.
That being said I would recommend folks DO NOT try the same setup. We were 100% aware that we could blow something up but YOLO!!
Do you not get throttle closures on your logs?
Thank you for your work for the community, cheers!
Thanks for following along and supporting the channel man. We are all learning together here. I didn’t know this stuff 3 years ago, CZcams has helped me learn!
Glad someone finally covered this 🙌
We have been talking about it for over a year in the group chat, but just havent had a chance to put this vid together.
Well well well, that explains it all. I remember the V5 OTS maps being aggressive as hell. It certainly explains Swap Depots 500+up dyno as well, can't recall the full numbers but it was impressive stuff.
Cheers for the clarification and Gary is a madman 😜
Thanks for this great info guys! Thanks for sharing all your knowlegde. Have a nice weekend, Dutch regards, Nico.
@BMW1M Hey. I heard of them indeed. But didn't do any research on new turbos yet. My e93 is only at 93k km's. So there is some time left in the OEM ones. There are not many 335i n54 in my area( south of the Netherland) Actually I did not see one single e93 335i n54 since oct 2019, when I bought the car ( in Germany). I'm collecting a lot of information about the engine and replacement turbos. But now, I'm saving money to buy 6 index 12 injectors at the dealership. (€2450). Dutch regards, Nico.
after watching some of your videos i sometime feel l as if my n54 platform knowledge is not near to what i thought it was LOL , that is why i love this channel, i learn something on every video. thanks again.
I say it alot. "you dont know what you dont know". Im still learning as well. Its an amazing machine these n54s.
Really good info. Thanks for the video
Fantastic vid!
Ill be doing a dyno video here pretty soon actually and ill do it with port injection off first to see what the numbers are, im pretty sure my power is gonna be lower then the power i made with the OTS v5 buuuuuut i think my 60-130 time is better now because it still wants to pull up top unlike the OTS map
Yeah I'd imagine cleaning things up at the high rpms would really make a lot more power
Thanks man! Keen to see the results!
Very cool, keen to see the results, as yeah your 60-130 didn't quite line up with the Numbers on Dyno, be nice if you can get into 6-7 second range for sure
Thats be awesome to see the 3 dyno results side by side !
I need to try that map. YES!!
Just remember it’s playing with fire when you start tricking the dme like this
I’ve ran 11.1 on my stock turbos rwd e92 and everyone at the strip seemed surprised. There’s also some other guy on CZcams who ran like 10.8 or 9 with his rwd stock turbo e92 but he’s got a 15 conversion and skinnies. Crazy what these cars can do with a proper set up.
Absolutely. Stock turbos can make power especially mid range. Crank the timing up and make use of the boost that’s there and you will have a fast car on stockies
thats me ;)
@@Silent9n54 nice!!!!
I ran that v5 map for a day 💀💀 shit felt crazy I’m on custom tune now at 17 psi running good 🙏🏼
perfect guide 👌 ✨️
Wish we had dragy video of the 6.7s 60-130mph/5.7s 100-200kmh run! Not sure how my car held up so well with no fuel upgrades other than a walbro 450 lpfp and index 12s. Definitely a map I might never run again lol. Was running open downpipes in that second clip of the 0-60 with the boost gauge, we could hear it back at our house a mile away!

Thank you for understanding 🙏
You can also adjust your waste gates to push more if you really want too
Well you can adjust the effect of x amount of wgdc by doing the rod adjustment.
Ali who seems to be a partner with vehicle virals also did the same thing with his 17t car. He made like 580 on a Dino in hot Florida weather.
Yes, spot on!
I'm just curious who has the fastest quarter mile on ots v5.e40 with 17t hybrids? Currently in some hot humid Texas weather i went 10.42@135.

Crikey Andrew, you sure know your shit on this platform. I guess you get that when you live and breath it 👍
Been around that’s for sure. Also speak to more people about n54 setup than anyone else on the planet.
@@ZeroTo60Tube yep I figured as much, I'm super keen to get into the platform but do actually get a bit overwhelmed by all the cambus techo stuff etc, I know the mechanical side of engines and making power etc with turbo systems, have built full custom turbo setups blowing thru carbs back in the early 90's. But I guess I don't need to dive as deep into all that techo stuff as you do, as long as I'm using a decent tuner like Wedge.
what are your thoughts on mhd v10 on 17t turbos ?
Very very nice and informative video. Just one question in case that someone upgrades to bigger turbos, is it safe to drive the car with the stg0 map until he gets a custom one?
It should be ok. Just don’t beat on it too much
Got someone in the U.S ran a 9.9 sec pass on the ots mhd e40. Granted his car is heavily gutted. He just got it down to a 9.6 with tuning from pure evil tuning.
What turbos
Didn't want to believe I'd blow mine up on the v5 e40 and 17t's, but it happened. Cracked ringland on cyl. 5. I did have a 3.5 map sensor though.
It commands huge wgdc for hybrids. Turbos will still be making all the boost and heat. But also fighting throttle closures.
On the flip side people break ringland on stock tunes as well. The joys of old cars.
How was performing before it broke?
Also lost ringland on # 6 it’s mainly a heat thing not detonation as Andrew also lost his motor running a ton of ethanol and enough octane for the tune, Check out the single turbo guys their egtees and aitees are mostly way cooler than the twins and they run unopened 54s for many years and banging hard on them with plenty of boost
Looking at these comments and there seems to be A LOT of people running the China 17T or 19T turbos - I’m looking to upgrade my stock turbos and the VIV V4 turbos is looking like they are worth a pun? Welcome any feedback.
I think the V5 also had the knock tables adjusted. Running the car like that might get good numbers but you're really rolling the dice every time you go WOT.
You are spot on. But we’ll knock reduction for another video. There is a reason it’s an option when you flash any mhd

@@grizzlycali4508 check your throttle on V10, its likely closing. I find the V7, V8 maps don't have throttle closures on my smaller than 17t but larger than stock turbos.

Would be awesome if MHD came out with a hybrid turbo OTS map pack @Wedge performance .. that would be a hot seller 🙌🏼
Well the issue is the variance in setups. An ots won’t work for every car. It’s a no brainer to offer a cheap tune for a hybrid setup, but the issue is it won’t be right for everyone and he will still need to put the work in to get it right for the specific car.
Once you have base wgdc sorted, it’s then on to timing and fueling to suit. And a mediocre effort on the tuning side isn’t good enough for hybrids pumping 25psi.

@@HDGnvrsleep no break in required. but you may break them on OTS maps. :P

Would you be able to run v5 e40 while running port injection?
No, the problem being the di will be trying to do all of the fuel. With port injection you need a better blend between di and pi as the car starts to make power. With v5 she’s making all the power with out looking for pi
Damn. That's crazy...the fastest I've ever run was 124.5mph in the 1/4 mile at 21psi and 13* of timing...I've never been able to get a 60ft below 1.9...this run is insane and makes me want more power.
That's identical to my trap speed at 21psi, but on pump gas with 7.9 timing, there has to be more in it.
Every 10th in the 60ft is 2 10ths on the 1/4 time. Apparantly.
@@ZeroTo60Tube well shit, if I can match that 60ft then I'm into the 10s...I've got work to do
@@17t135i I'd have to guess your rwd? I can't see why I'd be down on power with more timing...none the less, impressive trapspeed on your end

Very interesting, I got a pair of 17T eBay turbos and running 3.5map sensor and MHD Stage 2+ for 91oct, am I going to blow my engine? Also have stage 2 fuel pump.
Probabaly but not because of those item’s specifically they just all blow at some point. Be ready.
However your setup will absolutely wear out the turbos prematurely. The turbos will be overboost long and fighting throttle closures continually.
@@ZeroTo60Tube I hope mine last a tad bit longer, car only got 110k miles. I did all the preventives as far as I know (index 12 fuel injectors, colder plugs, new OEM coils, new HPFP, new stage 2 LPFP, OCF gasket, FBO, Inlets, walnut blast, oil catch can) anything else I should consider to keep my motor from blowing up?
I read about the throttle closure on the V10 MHD map, not sure if I've experienced this yet. But I am running stock DVs and still get some flutter between gear shifting.
Is the V5 E40 map with stock turbos riskier to run for the motor than V10?
Or is it just more likely to wear out old stock turbos quicker?
I’ve read some comments saying V5 has desensitized knock tables
I hope someone answers this…
@@hazel8689 I have ran v5 93 or e40 on all my stock twins cars, cars with over 200k miles on stock twins. It's the best map... v10 isn't as fast, verified by many nights in mexico with identical cars... same mods same ish weight, we would run v5 on one and v8/9 (back in the day before v10 came out) on the other. The v5 car would win every time, then when we retuned in the parking lot and reran, suddenly the other car on v5 would be faster. A couple car lengths 60-130.
The knock tables definitely are not as desensitized as that forum post says, and certainly not enough to be dangerous. The "old stock turbos" will go 250k+ with proper maintenance.

Is there anyway to diagnose a bad torque converter on the ZF6HP21?
I’m having terrible vibration and vehicle shake usually when I’m taking off from the start around 25 - 30km it’s quite random.
There are a few symptoms of bad converters but it’s normally hesitations or loss of drive. No vibration. Vibration like that can often be drive shaft bearing
@@ZeroTo60Tube Ahh easy man essential my gearbox had a issue so I replaced it with a donor gearbox & now it has massive vibrations around 25km when going from a stand still, it happens all of a sudden and scares the shit out of you & then goes back not normal so issues on the hwy or any other driving.
Mechanic did a scan no codes are coming up he thinks it’s the torque converter.
Just wanted to get your opinion on this as I trust your opinion more.
Essentially to sum it up shift from 2nd to 3rd is extremely harsh and it doesn’t occur everything time.
@@bhaskarakovvuri707 its very hard to diagnose with a breif description, so please dont take my word over the mechanics. I have never had a comverter fail so i could be wrong,.
don't the v5 maps also have desensitized knock tables?
Yes that’s for another video tho.
Wow. Ive been fighting Over Boost trouble since I've put in the 3.5 sensor and the 17't turbos. I've been looking for info on this and finding very little on the net. There are quite a few of us out there trying to find help all fighting codes like
2D33 - DME: Absolute-pressure sensor, intake manifold: signal.
2F0C - Intake air temperature sensor.
30FE - DME: Turbocharger, charge-air pressure too high.
3100 - DME: Boost-pressure control, deactivation.
2D2E - DME: Throttle-valve angle - intake-manifold vacuum, correlation.
One thing also is that I'm still running a 5' stepped intercooler as are a lot of those that get these codes. As well a lot of people having these codes often it's the Boost Solenoids that are giving troubles. But there are even some pros that have been fighting with them. Trying to figure out WGDC and Boost targets etc. As well we seem to have all replaced both our Map sensors trying to stop the codes with no luck. But until I can put in a 7.5 intercooler I will try to check out the v5 MHD map and switch back to my old sensor and see what I get. I LOVE THIS CHANNEL!! Andrew you have your finger on the pulse of it all!! Thank you.
You are making too much boost and the dme cant automatically correct it. Now you know. It will prematurely wear the turbos fyi
I actually installed a 3.5 bar sensor for a while, and when running ots maps the car would cut power, throw an engine light, and was throwing some of the same codes. Actually reinstalled the oem sensor and it runs much better. On v10 stage 2+ 93oct it only runs about 19-20psi it seems. Keeping the 3.5 bar sensor on hand for whenever I decide to bite the bullet and get a custom map.
@@ZeroTo60Tube But how do I stop it from doing that? I've tried the lesser maps on MHD but the same thing keeps happening even at only 15lbs boost. I'm believing at this point I need the larger intercooler to match the boost readings the DME keeps getting?
The 30fe is “over-boost”. The 3100 is just “we have a boost problem activate limo mode”
The correct answer is go a custom tune so base wgdc suits your setup. However as Christian mentioned stock tmap and it will run better. Not safer. But less codes.
Do u think stage to stage can beat on roll race an Audi s3 ??
Unlikely. The audis are properly quick.
Is there a similar china 17t like option for N55s?
There are some hybrid options for the N55, however they dont make the power of the n54 17ts.
@@ZeroTo60Tube Thanks. I guess I'll keep saving Pure Stage 2
I’m new to bmw but why not just put a aftermarket boost controller on and boost gauge? Also my buddies 18 mustang gt runs 8.7 in the 1/4 with stock internal engine, bolts ons shot of nos and e85 tune.
You can. But those cars are not smooth to driver and a flash only car.
I tried this map on my 17t with the 3.5 bar and was only making about 19 psi.. do you think if I swapped back to the 2.5 bar it might make a difference ?
So the 3.5bar sensor sees the high boost and closes the throttle. If you run the 2.5bar sensor the DME wont see the high boost. MHD wont show any higherboost but you will be making over 25psi real boost
@@ZeroTo60Tube I’m only hitting 19 on the 3.5 bar.. you think the boost will go up that much with the 2.5 ??
That’s a lotttt more boost
QUESTION when you say KILL MAP at 9:30 does that mean it will kill you motor?
No no. Well it won’t if the hardware is in good condition. You’ll be “killing it” racing others. But if you have a dodgey injector, or ignition issues the v5 e40 map just won’t work properly.
V5 E40 19t loading😂😂 is it then safe to run the v5 e40 on the 3.5 tmap ?
No point on the 3.5tmap. It will just close the throttle
I just finished the install of my 19t v4s. It was fun but challenging on jack stands.
Currently limping the car on MHD stage 2v5 93. The car flies but I am being very careful until I get a custom tune. It’s doable but I would try to go out racing like this.
My brain hurts 😀
Ahhh it’s all full on first.
my 2010 135i seems to like the v7 93 stage 2+
To be brutally honest, if the hardware is on point V10 should be the best. or if you are doing trickery with hyrbids like this v5 e40

@@ZeroTo60Tube tuner recommendations ?
@@HDGnvrsleep Ken from wedge hands down! But be ready to have the car tuned. Make sure hardware is on point. He gets the cars running through the entire range so well. Its easy to make peak power, or dyno figure. But not easy to make them work in the real world through the entre rev range and gears. Ken is also still very passionate about N54s, he has 3 or 4 perosnal n54 cars.
Pretty sure NHRA requires parachutes, and other safety gear once one hits 10sec 1/4”. Or at least tracks I’ve been to in my life
Even with a 3.5 BAR TMAP and hybrid twins, is an OTS map still going to have the same negative effects or is it safer?
Pointless. It will hurt the turbos. Wgdc should make 18psi on stock but making its 25+ on hybrids so throttle closes and turbos fight it.
@@ZeroTo60Tube out of interest is there a chance the car is closing throttle even if it doesn't show up on the logs? i.e throttle stays at 81% all the time?
@@dextershumba7262 not, if it shows 81% the throttle blade will be open all the way.

It’s definitely possible. But a huge task to understand how to make it all work. Easiest way is swap all the modules with the drive train. However you will have mismatched vins in the cas to the chassis.
It will take hours to explain everything you need to do.
Good info, but let's make sure people understand that running an incorrect tmap just means you have no clue what is REALLY happening by the logs. This is akin to using an FMU on a turbo car instead of a proper tuning methodology. Fox body guys used to crank the distributor and lock it so it ran super high timing the whole time. Made it a bitch to crank but would do good at the track. Get a real tuner and not just throw parts at something to see what happens.
Nahhhh what better way to learn than blowing something up…….. jokes aside I tried to make it obvious. But people won’t care. Hopefully it raises awareness for the need of a custom tune with hybrids
Wow. Shows you the improvements in engines. On BM3 E50 maps on my B58 car, it targets 17.5 degrees of timing. I get no corrections at that as well. 98 map (93) targets 12.5 degrees of timing - i dont think 13.5 degrees is a "lot" on an ethanol map.
It's not quite as simple as that, my N55 ran 14 degrees on only E30 fuel with hybrid turbo, custom tuned, but my N54 with 17T with 8 degrees is a much faster car. 600whp 17T cars typically 12 to 13degree with 26psi plus
I haven’t looked in to it, but is the n54 higher comp?
@@ZeroTo60Tube N54 is 10.2:1 B58 is 11:1 but as vtecnet suggested it is a combo of boost pressure and timing for power so if you make a shitload of boost you often cant run as much timing. Ideally want the turbo in the meat of the efficiency curve and then work on timing there
In regards to the times etc....how trustworthy are these app/GPS timings? Personally id take anything being recorded in that fashion with a grain of salt.
More accurate than you can imagine. Generally with 1 100th of a time slip.
Was his fuel rail ported?
No stock hpfp system
@@ZeroTo60Tube no way that's crazy! Now I'm tempted lol. Btw I messaged you on another platform. I drive a 535i
@@grizzlycali4508 I won’t reply on any other platform, just so you know. Insta and Facebook have 1000s of messages I’ll never to. CZcams is where you contact me for questions.
@@ZeroTo60Tube so I filled up e40 and flashed to that map today. The car seems to like it. Did a pull here n there and no limp mode or anything
@@ZeroTo60Tube in your opinion for a tuner to go with... jsr or cd919 and asking based on my set up being a 535i fbo 19t's? I think from what I've read/heard about they both would be good.
Mine closed throttle horribly it was so violent
Got to hide the overboost from the dme
In my ECU I have N75 Base 1, N75 Base 2, N75 Lift 1, N75 Lift 2 and N75 Max. Then there is Turbo map 1, Turbo map 2, Turbo map 3, Boost Limit at Altitude and SVBL. It's really, REALLY difficult to set these up on a new turbo setup without any base maps. This is on a BMW diesel btw, but that's how most factory ECU's control boost. I am having so much fun! 🤡
Sounds about right!
First
if you aint first you're Viktor!
I wonder how the MHD V5 93 map would do on these
The 93 map doesnt target as much boost as the e40, so the turbos cant run beyond the scope of the stock tmap, so power is down a lot on the 93 map when used this way.
@@ZeroTo60Tube I'm currently on Mhd 1+ V10 and the car pulls great on 17ts ,6+6 blades
@@chriscee546 as explained in this video it will it be pushing the 17ts much harder than a custom tune. Just remember it will be fighting throttle closures and prematurely wearing out the turbos.
@@ZeroTo60Tube I am getting a custom tune shortly
@@ZeroTo60Tube I ended up getting custom maps from CD919 and the car is running amazing with almost 0 timing corrections during wot 10 second pulls etc also mixing in E85 made a huge difference
why havent MHD released a tune for 17/19ts?
I'm all over that question too. What's up MHD??
I think there's too many variables, ie there are 6+6 and 11 blade versions of both that behave differently, the wastegate adjustment can vary, other supporting modifications vary such as stock location inlets, relocation inlets, lpfp upgrade is required at minimum, an ots map wouldn't unleash the full potential.
@@17t135i yeah but the stage 2 etc requires cats etc, I'm sure they have had lots of time with the types of hybrids
@BMW1M everything comes from there, mhd don't endorse anything by offering alternative tunes
My take is the setups vary so much. And when you can flow this much air, there are too many variables for a “close enough” wgdc to work as an ots.
its all in the 60 foot, nothing fake about that pass. If i managed a 10.88@125 on stock turbos with wedge on the sauce, no reason why you cant run even deeper 10s when trapping 130s . czcams.com/video/CYPZEw1PC4c/video.html
I will give everybody some free advice use ken from wedge
He knows how to make them not only fast, but smooth. Oh and cool cracks on the shift
