Pretty cool vid. Would be awesome to make a quick vid on dual vanos tuning and maybe showing a full example with the entire process.
Dual vanos you're doing the same thing, just tuning Intake first, then exhaust. One at a time, on/off
@@CanyonTuned that makes sense. Elegant and easy. Perhaps pin your answer for the dumbasses like me that couldn't figure it out hahahah.
Thank you and keep on the good work, this series rules!!
Actually for future reference, it seems that dual VANOS (M54 and later) is not on/off like VTEC or single VANOS, but adjustable by angle. First intake, then exhaust is a good approach for tuning it, but it's not going to be setting an engagement point like is shown in the video, but actually setting cam offset angle by RPM/load in a 3D table.
Also, this means that it's much more important for the seals to be in good condition as much more control over small changes in hydraulic pressure is required for dual VANOS.
@@carloschip Hey. To my knowledge this doesn't really make sense on a mechanical level. Vanos is actuated by a solenoid that lets oil pressure build. This solenoid doesn't seem to work by duty cycling or anything like that (you can actually hear it click when you cross the rpm threshold). So, if the solenoid is an on/off switch. How could you adjust it by angle?
This is just my intuition and of course I could be wrong. As such I'm absolutely open to get corrected here! :D
@@XabiIglesias it has a helical screw i think? But all I know is that you can tune 3d vanos tables (exhaust and intake) for the e46 with angle offsets per rpm and load. They don't quite look like the 2D table he presents in this vid.
Thanks for all the great tuning videos! I'm always coming back to them as I slowly buy parts. I saw a similar video from Crank about VANOS tuning and he said it takes about 1200 RPM to switch VANOS on and off, but this video you say it only takes 2-300. I couldn't find any other info on it so I was hoping you had some extra input!
Honestly it depends on the condition of your vanos. If your internal seals are good it will hold oil pressure and switch the cam angle faster. If you have a worn out unit, or old parts it could take that long sure. There's some programs out there to manually engage vanos like INPA you could trigger it, and look at your cam angle/vanos angle real time and observe how long the move takes
Thanks sir CZcams training course
Great job, thank you for this videos, now I'm closer to tun my car
Great sequence here from beginner to advanced tuning. I think you teased it in the intermediate video, but did you ever cover MAF scaling?
Yeah I'm pretty sure either the intermediate or advanced covers maf scaling and a link to the spreadsheet I use
I know this is an old video, but I am in need of some help I did a m50 manifold swap trying to get the tune dialed in, I am trying to log engine load to dial in fuel but it is at 0 load I don’t want to have to manually calculate load. I am a bit confused why load just isn’t logging any ideas?
You need to make sure it's actually checked in the list in romraider logger. Are you seeing a live readout of it? If not, you could have an issue with your wheel speed sensor, crank signal, or maf
Awesomee! 🎉🎉from Spain
Thanks! 😃
@@CanyonTuned just one question: which gear should be choosen just to test (street not dyno🤣) the fuel base map or ignition map?
@@amadiurs For part-throttle/cruise fuel and spark tuning you'll want to cycle through every gear and as many driving conditions as you can (up or down hills), brake boosting, etc to hit as many load/RPM cells as you can. For WOT tuning with a wideband, I'd pick 3rd. But again, the more data the better
Great video mate! Is it possible to do a bigger video about Fueling and long term lambda corrections?
The process is pretty rinse and repeat If you follow the steps in this video. You'll be able to dial the car in better if you have a wideband logged at the same time. Cuts the fuel tuning time/logging by a lot
Hey man good work! So if i do a direct exhaust with no cat i have to tune the fuel right?
Not really, the stock ecu can add or subtract up to 25% automatically. Take a look at your fuel trims. If it's pegged after the modifications it might be time to update your fuel table
Awesome !
Thanks for sharing. Useful information.
In order to remove pops and bangs, do I just do opposite what you’ve showed?
I hate that noise during deceleration, especially with my new straight through exhaust.
I would suggest finding a stock bin in the rom raider forums and use the compare feature
@@CanyonTuned mine is basically a stock tune.
@@tiitsaul9036 Stock tune doesn't have pops and bangs, idk what you mean. If you have "basically a stock tune" and it's doing it....Either you have leaky injectors or a missfire
@@CanyonTuned hmm interesting. Wasn’t noticeable with stock exhaust, but with straight through exhaust it burbles decelerating ( especially down hill when engine is cold)
Is it possible the catalytic converter maps are the cause. I no longer have cats and no need for cat warmer tables.
Hello again!! I want to ask you something because i finded different kind of opinions. Yesterday i logged mine. (Catless headers with O2 deactivated via romraider and CAI) i found that during a WOT in 3rd (800rpm to 6500) a constant knock exist (0.2 to 0.5) but during 3000-6500 aprox y find random cells with values between 1 and 1.9... what do you think? Thank you!
Try to pull 2 degrees of timing across the board and see if it clears up. If not, you may actually have a faulty knock sensor or possibly a damaged section of shielded wire that protects from electrical signal noise
@@CanyonTuned Thank you so much!! Yesterday i made a good log across 2-3-4 and 5 gears at wot (knock between 0.8 and 1.3) and cruissing (0.2 and 0.8). This week i will make a good thread at romraider or ms42 forum showing the logs and triying different solutions.
Can u show how to change ms41 to ms41.2?
Nice work dude!
Not many people do that so I probably won't make a video. Just search the romraider forums I believe there's a post on it
Thanks bro !
Please for the next do vid about romraider dyno. How to edit cars_def.xml for bmw's how to dyno and etc.
Follow this tutorial to get the dyno working: www.romraider.com/forum/viewtopic.php?f=58&t=15385&p=140867
Hey would u sell a tune i can’t do all that
There's plenty of companies that sell tunes. I don't sell stuff due to liability
Hello, will this work for a MS45.1? I have an 05 530i that I just did the M50 manifold swap on. I want to now dial it in.
Tables will be different but your general steps will be the same
Hi ,can i log from x20 ? If i can't how can i made my own obd2 port ? Thanks..
You can log from the x20 just get a obd extension cable to run it inside the car
One question: My car limits itself to 5500rpm (maybe VSS error) sometimes and im wondering can I fix that and change the value to 6500rpm? Its a 316i 1996 swaped to the m44, 318ti 1999(has 318ti ecu)
Sounds like a crank position sensor issue, nothing related to the tune
@@CanyonTuned crank position sensor was failing and was replaced but not with an oem one :/
Cam and crank position sensors, oem only!!! The dme doesn't like anything else
since the ms41.1 and ms41.2 are the same ecu but have a different software is it possible to throw a m3 rom onto a 41.1 and then upgrade to the custom 41.3?
Follow the guide in the rom raider forums first to convert to ms41.2, then do a full write with the m3 code. Also the ms41.3 has not been released yet
@@CanyonTuned the files are on the open ms41 page wym?
@@JakeW50 they give you some bin files, but not the definitions. I reached out to the creators and they told me it's still in a closed beta test
@@CanyonTuned gotcha gotcha, as for the 41.1 to 41.2 conversion, do you happen to have a link to the forum were they discuss convrting it?
im having an isse where i tried to read my full, it said error connecting to ecu for a bit and once it finally identified it it rear it like 5% said there was an error with the data and now my e36 wont turn on
did my ecu shit itself?
I would try a different cable or its possible your checksum isn't correct
@@CanyonTuned brand new ms41.1 and cable, i hook everythig up and plug in the cable, flashtool sees the cable, identifys it the first time and then once i start reading it says packet response error, followed by an error communicating with the ecu, when i try to write it also says error communicating with ecu
@@JakeW50 are you using the round connector or obd port?
@@CanyonTuned i figured it out now, everything reads and writes goos now but to answer your question i was using the round 20 pin port
20:00 10% wouldnt be 1.10* ? 1.01 would be 1%, or im wrong?
That's correct
Hello, it is a great video!
But i have installad romraider the same version you have. Romraider ecu setup works perfect! I can see the tables and changes some values an flash to my ecu.
But one problem, i can t run romraider logger. The logger definities i have. That s ok. But i can t find out wich car def.xml is need?
www.romraider.com/forum/viewtopic.php?t=10695 you need to make a romraider account to see the links.
@@CanyonTuned ok. So i need a specific logger definitions for ms42? Is also on the romraider forum?
@@AK-pm6nu Is this for MS41 or MS42? There's a different section in the forum for MS42. All my tutorials are for MS41.
Is for ms42 ecu
It is for ms42 ecu but i think there is no big difference between ms41 or ms42 for logging on romraider, the value s are different but logging it self is same. I want to run romraider logger for logging my ms42.
hi if i have a turbo where do i modify my turbo psi ?
You would need to run the ms41.3 custom software. It has boost control
@@CanyonTuned okay thx u
hey mate, having some trouble doing partial read on siemens flash tool. says cable is connected and have bridged pin 14 to 18 on 20 pin adapter and have cable with correct chip. when trying to read nothing will happen. any ideas? ta
What ecu? And have you tried with the 20pin round connector adapter?
@@CanyonTuned yep am using the 20 pin adapter as car doesn’t have the other port inside. Unsure what ecu, it’s a 98 323i. Is it only pins 14 and 18 on the adapter that I needed to connect together? Ta
@@josephpalumbo9705 323 ecu is different, it may require a different flashing application.
Try this one: www.ms4x.net/index.php?title=Flashing_Tools
@@CanyonTuned gave this one a go but is coming up with ‘could not write the date to the serial device’. I’m using the 20 pin adapter and have bridged pin 14 and 18 inside it. Any other pins need connecting? Ta
The ignition tuning method mentioned at 25:35 is NOT how you tune any engine. You have at that point made no logical reasoning to why adding 5deg makes any sense. More ignition advance is not always going to give positive benefits.
This is literally what every other "tuner" does on these cars. I've looked at RK Tunes, kasle performance, etc. They all just add 3-5 degrees across the board. I agree for proper ignition timing you need a dyno. Torque will fall off if you're too far advanced but these cars really do like a few extra degrees of timing. Also, if you're adding an m50 manifold you want to pull timing up top and add timing down low. Also move the vanos engagement point lower too. I'm not an idiot 🙃
