Great work man, the video is very detailed and gives the right amount of information that makes it useful and not intimidating for beginners.
Ayee thanks for being #1000!
Yesss🙌🏼🤙🏼 been waiting for this bro!
Thanks! I might do a part 3 as well take a dive into logging
@@CanyonTuned for sure! Looking forward to that, also… I realllly want the launch control but I’m on MS41.1 how do I convert to MS41.2?!?!
You are a legend!!
Part III logging is here! czcams.com/video/Rdc3O5Pjyw4/video.html
thanks dawg, very good info
Burble tune works!
Great info bro.
Hell Yeah bro!
Your a G brother thanks for the info
great video..
Thank you 👍🏻
thanks very much for many advices!!!
My pleasure!
Awesomeeeeeeee
Thanks Bro!😁
Hello. I have two questions: is there any major difference between ms41 and ms42 when it comes to tuning them? Second one: Im installing a bigger intake (m54b25) to my e46 323. Is there any parameter that you recommend that i tune other than fueling? Have a nice day and thank you for the awesome videos!!
Not much of a difference besides loading different rom Raider definitions. Just remember to log fuel trims to see what fueling adjustments need to be made. Idle fueling may change as well. You should see tables for that too
I know the ECU can be switched from an auto to a manual , bimmerforums has a pretty good description of how to do it , but it requires a pc with a serial port . Is this something you can do with the software you’re using and the USB cable ?
See part 1, you just need USB. Manual conversion can be done through rom Raider as well
so when it comes to the launch control option, would that include most e36's or just the m3?
It's technically not launch control, it's just a lower rev limit set when the car isn't moving. But you'll need to switch to ms41.2. If you're on 41.1 it won't work, but there's guides on how to switch in the romraider forums
Hi @canyontuned, do you do custome tunes as a service? I'm in Phoenix and would like to find a local tuner.
Message me on Instagram, same username
I know that you are probably tired of me 😂 but I finally got everything to work but when I do the LC I followed your section on it but now i can’t get it to rev over 3000rpm how to I change it so I can still have LC but when I’m not using it still let me go above 3000rpm if that makes sense.
You need to set the the RPM limiter only for low speed less then 5mph, above that set your normal rev limiter
When you say across the board on the ignition timing and fuel do you mean all the way across the board or just the 50 column down
Timing I add a few degrees in every single cell, fuel I don't usually touch unless some of the fuel trims are way off. Do some logging before you touch that table
Hello. I have one question:
Why I don’t have diagnostic trouble codes options and at folder limiters, engine speed limiter (mt) or (at).
I have latest rom raider from may 2022.
Thanks
What vehicle and dme version? Make sure you have the right definitions for your specific car
I have a 96 E36 328i which has been mapped like this but I think it's off as it runs really rich. Is there an easy way to flash it all back to factory?
The romraider forums have all the stock bins. You need an account first to see them.
It is the same for e46 320i or i need to see another tutorial for E46?
Basic tuning process is the same, but the affected tables are completely different. Also your MS42 flashing tool is different
I appreciate the vid! What definition file did you use? I tried with the latest 45.9 and iam missing the engine speed limiter setting... Any ideas? Thanks
Definitions can be found in the first video (ms41 wiki page) one of the first pages will have a link to the definitions. Depending on your ms version you may not have certain features available. Also make sure you get your definitions from a reliable source
make sure that ur MS41 version is the same.. His is MS41.2.. mine is MS41.0 so i dont have the engine speed limiter (AT) and (MT)
Is there anyway to program an on off switch based on throttle position with a stock ecu? I have a supercharger with a magnetic clutch and I want to have it turn on when the throttle body reaches a certain point. If not, do you suggest any way around this?
There's WOT logic in the ecu but I don't think you can trigger custom events, you may want to look at the wiring pin out on the pedal itself and see if there's a wot wire. Tapping off that signal and running it to a relay then to your supercharger might work
In ms 41.2 there is map for muffler flap solenoid, that should work to control supercharger with magnetic clutch?
Can you tell what exactly i need with the EEPROM etc. ?
I have another video covering this
hii! thanks for all this videos! I appreciated it a lot. One question: Is it possible to tune fuel map (for instance) without a wideband? only with the narrowband that is installed in a standard car (e36 325i for instance again jjjj)? I was wondering if it is a good idea, tune it by myself, car and PC. :D Thankkksss
Yes, very easily. I think one of my other videos covers this but you'll need megalog viewer and make table with the same axis as your fuel table. Then log fuel trims and plot long term + short term and make your corrections based on that. Fuel trims are based on your stock narrow bands. So as long as their in working condition you should be good. Try to get your trims within 5%
@@CanyonTuned I will try it! Yeesss I watched your next video about this perfecttt
🥳🥳🥳🥳
any video showing the burbles?
Check out my pov driving videos. I have one with an external mic at the exhaust
My BIN file (partial from my ECU) does not have the "Engine Speed Limiter" (AT or MT), nor Speed Correction, so no rev limit limited by speed, then no Launch Control possible 🙁
Yeah so you probably have ms41.1, there's a way to update to ms41.2 but I've never done it personally
Can i follow the burbles feature setting value to my ecu? Or thats just example number on the video?
You should be able to copy my values
I keep getting checksums corrections when I try
Yo on the LC part I don’t have that section I have everything but the manual and auto settings what kind of read did you do ?
It was just a 24kb read, not a full. You could have old definitions files or your specific DME doesn't have those tables. Sometimes those NV motors or 4 cylinder versions don't have a lot of the same tables
@@CanyonTuned I have a 328i motor in my m3 and the ecu is a MS41.1 what MS version do you have?
@@moddingjr7797 Same thing MS 41.1 make sure you have the correct definition files the tables should be there
I wondered if you can flash a 320i m52b20 with the M3 ms41.2 file? would it work? or can i somehow copy the m52b20 map to the ms41.2 version?
You can go from MS41.1 to MS41.2, people do it all the time. Search the romraider forums
@@CanyonTuned i have looked at the forum, but do you know if you can swap the m52b20 file to the ms41.2 flash?
I've never had a reason to look into it, but you can attempt to do a full write (128k file) and see if it works. Just be careful because it could brick your dme. I'd start looking into if the processors and dme pinouts are the same across them first
When doing the 2 step and adjusting the fuel and timing would that also affect driving in those rpm ranges or just when 2 stepping?
The 2 step feature is only a lower rev limit when you're not moving. Timing and fuel can't be changed related to that. Only the main tables
@@CanyonTuned okay thank you! One more question, so when you set the low speed rev limiter and talked of adjusting the main tables for shooting flames like a sort of 2 step, wouldn’t those adjustments affect driving in the 3000 rpm range because it was adjusted on the main table and would not apply only to when you aren’t moving/under the speed you set rev limit too
At 3k rpm you're hitting different airflow cells in the table free revving vs driving. Do some logging in both situations and you'll see which cells are specific to free revving with no load on the engine
@@CanyonTuned okay! Thank you so much! I’m doing pop and bang and decel and gonna try this to hopefully get a flame shooting rev limiter! I’ll let you know how it goes
So educate me whats the difference with what my tuner does?
They should be following a similar process
Hey man, can you tell me if there is any index explaining what each option on the map means?
Yes every table has "table properties". Right click and choose table properties. At the bottom of the window it will give you a brief description. Also the ms41 development rom Raider forum section has everything defined
Thanks!
One more thing, in ms41.0 it doesn't have the rom limiter for speed. Is there any alternative to be able to launch?
@@gustavopaschoal7882 I'm not too familiar with ms41.0 but you might be able to wire in an auxiliary input to the dme that would trigger it
@@MikeP41 Could you tell me where I can find some information about it?
I don’t have the option for engine speed limiter “AT”
It depends on what MS41 version you have
Damn I just spend 160€ for getting this programmed... could have saved a lot of money by just watching this
Maybe you can charge other people now 😎
For the pops and bangs are those values only for m3 or can i use those for my 328 ?
There are a number of people who are reporting missing tables that are in this video but don't show up on their 328 tunes. Some of the values might be slightly different but the overall process should be the same
@@CanyonTuned Thank you for all the help seriously you’re the best for this ! It worked haha 😆 with no cats should I be worried about adding too much fuel on those first cells not sure what too much fuel would look like ?
It's going to heat up your exhaust valves with too much fuel and negative timing so moderation is good
Hey i dont have the map you used in limiters what protocol do you use?
What definition are you using ?
P.S. GreT video !
I don't know what you mean by "protocol"
@@CanyonTuned sory i mean what ecu definition file are you using ?
Go to the romraider forums and under ms41 development the first sticky post should have the definition files. I think you need an account first to see them
Im here in Mesa. Do you actually do tuning for other people?
It depends on what you need done. Message me on instagram
@@CanyonTuned whats your IG
@@davinsrandom3142 same as my youtube channel
anyway to flash an ecu from auto to manual on an e36?
Yes please follow the instructions in this video: czcams.com/video/-dFAqbgDHqk/video.html
@@CanyonTuned thank you!
Hello!! I have one question about logging, i have take a log looking for knock degree values, it was a wot pull at 2-3 gears. Always reading 0 so no knock. But i looked for LTV values (F6 at romraider logger) and it is showing some knock retard at certain rpm and load ... What values i should care about?
Clear out the long terms and see if they come back. If so, subtract that from your main ignition table, clear it again and see if it's fixed. You could have bad knock sensors, wiring or just a resonance at that specfic rpm the sensor is picking up
@@CanyonTuned Is it valid to clear the values with ms4x? I did it last weekend... I dont find a reason to getting absolutelty anything of knock at logging but the LTV menu show a little... Also a little difference between each 6 tables (cilinders). Maybe a bad coil/injector? Thank you!!
@@agdwhite5421 Clear the values in the LTV menu, and each table represents different load areas not individual cylinders. Look at the x-axis of the table, it's load. Y-axis is RPM. So just match that up to your main ignition table
@@CanyonTuned Nice! But i had clear the adaptation values with ms4x because my romraider logget doesnt have that option. I looked to the ltv tables after i did a short and chill drive with wots just up to 3500rpm. The 6 tables have the exact same load areas between them. How are they different? Thank you!!
Is there any way to do that in MS41 launch control ? Do not have that option… vehicle speed limiter in rpm and also don’t have dtc codes like you have
If it's ms41.0 or.1 you may not have certain features
@@CanyonTuned ahh, so basically not able to do launch control? Anyway to convert for ms41.2 ?
@@workout3389 You can convert from MS41.1 to MS41.2 but not MS41.0. You just need to flash a full bin from an M3, then copy over all your 328 specific values over like the fuel and timing tables. I think there's a guide on the romraider forums
@@CanyonTuned actually I have ms41.0 so nothing can do :c
I love the idea of you wanting to teach how to tunne but should do it step by step be open then all the world will talk about you
I can only do so much step-by-step. Some people need more hand holding then others. The video would be 3 hours long if I explained every little thing lol
@@CanyonTuned I think he means step by step on the important parts everyone should know like logging. Like how are you doing that with a laptop or tablet when the port is under the hood? Take us through a log session
@@gixxerhoff7502 Most of that is covered in my advanced tuning video: czcams.com/video/Rdc3O5Pjyw4/video.htmlsi=b7Oe5KoZzAjLFZs_ but for logging you just have to use the romraider logger. If you want to log through the OBD port you just need to jump pins 2 and 17 in the x20 connector under the hood. You can find more information here: sites.google.com/site/openms41/read-write-ms41/enable-write
once you turn off some of the emission stuff , do you think the emissions people will detect it being turned off , asking for a friend , also this friend lives in California , this is also hypothetical of course 😂
When I say "turn off" I mean the ECU no longer checks to see if there's errors against certain conditions. Or the thresholds are much higher. I heard California is eventually going to compare your ECU against a stock checksum to see if it's been modified but I don't think that's going to happen anytime soon
@@CanyonTuned thank you for your input , appreciate it !
Has anyone done any tuning for SC/Turbo with romraider yet?
I actually ended up switching to a vems standalone ecu, much easier tuning process on speed density. You can literally just drive around and have auto tune dial in a VE table for you
@@CanyonTuned Stand alone ecu seems to be where most self tuners end up if they stay at it long enough. Still it is really nice to see that you took the project to its intended completion. There were so many gaps back when we were looking at this a few years ago.
Is it possible make a single video how to do a cat delete step by step ?
Just get headers or cut your cats out, but honestly there's almost no benefit

How do i log aem wide band?
Wire up a serial to usb plug, then there's a drop down in rom raider to log it
@@CanyonTuned got it
The launch control did not work for me
Log your speed and see if your speed sensor is working
@@CanyonTuned also my pops didn’t work either
Honestly doesn't seem like the changes got written to the car
@@CanyonTuned nah it did cause launch control worked it just never turned off so it would reach a brick wall as I was driving
@@Awesomevideos51 Sounds like your speed sensor is bad then or you typed in a setting wrong. Rev limiter above 1 kmh should go back to normal
Makes me wonder how Kassel charges 250$ for this..
It's really not rocket science
