Is it possible that the ECU is encrypted ? Any suggestion in this case ?

Thank you !
I can encrypt it, but then it will only read nonsense which you definately can save. Make shure to save in a location the current user has rights to write in or start it as admin.

So... trying to run MS42 on alpha N. I know for a fact you can run ms43 without a maf.
Ms42 should be able to do the same.
M52tub25.
With maf unplugged, it struggles to start, when it does, it stalls quickly after.

Anyone know what the process is or what can be wrong thatís preventing the car going into maf fail safe mode and using alpha N.

Iím using RomRaider to edit ms42.

Without a real alpha/n code mod you will always get stalling or imperfect engine running. Thats part of the decision BMW took to make you aware thereīs something wrong ;-) However, alpha/n is just a single byte flip on both DMEs.

Has anyone figured out how to code out a brake pad sensor dash light?
I came from older cars so manually checking my pads visually isn't a big deal so
it doesn't really bother me. I'm running a full front and rear set of E82 brembo brakes and haven't gotten the chance to get to the wiring to trick the system.
I have the software so why not flash it out? lol.

Also curious on how to code out the airbag light if possible, since I'm running a NRG steering wheel.

Just guessing, but shouldnt that be on the cluster module? i remember that we could code the temperature gauge to show more realistic values, so maybe we can find the hex string of the brake light check?

Thanks for confirming that it also saves if encrypted .

Kind regards,

Has anyone experienced their parking sensors not working after flashing the ecu? I've tried to read the pdc module with ncsexpert but no luck, anyone know how to reactivate them?

Hello,

So i am gonna try the Wiki launch control today , however i dont have an issue , on the Wiki page there is Launch RPM Hysteresis , which i suppose it's " c_n_max_hys_max " in my TunerPro , even if it's not showing up in the LC folder .

But i also have Configuration Launch Control and i dont know what the value should be there . Could anyone tell me ?

Ill attach a picture of my tuner pro

Also , i dont want to make two posts , another question : My friends eBay ECU pops even when he changes the gears , it sounds like a turbo now lol , any table i should look at regarding that ?

Good day!

On the wiki in the community patch list page it explains the launch control config switch also I think the hysteresis values are taken from the main rpm limiter values, but I also think I saw a post a while back saying launch control hysteresis isn't properly implemented but I'm not 100% on that, and with the pops between gear changes I would assume that is done by going into the main ignition tables and retarding the low load tables

So i tried with the above settings , and it didnt worked . Then i decided to lower the hard limiter for the Neutral gear to 3200 and voila , if i keep the pedal pressed up to 50% the launch is there , if i press more , it goes over the limiter .. Not sure how legit this is , but it works for me lol .

I need some help on cloning my MS43 to one spare.

I did a full reading (512Kb) of my original ECU in bootmode with JMGarageFlasher, then I write in the spare ECU (it was from an X5), make a read again from it to verify if the file was write correctly and it is.

I installed it in the car and I can hear one click of the relay 3 or 4 times on passenger side that's not usual, and the car won't start. I cleaned all the adaptations in INPA, all errors and nothing.
After that, with the original ECU, the car works well. I don't maked any change on file.

You can test the dme outputs in inpa, just to see if they are working. Maybe its a pin. Did the temp gauge works fine or does it go to red?

Did you boot mode flash the spare ecu? Sounds like the immobiliser is preventing it from starting as if the ews delete is not functioning properly, I had the same issue

I didn't see that point.
but I connect the ECU with the INPA and see the vin number was correct with my car and some other parameters.

yes, in bootmode.
I want have the EWS working, because that I read the original ECU to try clone it. but will the full read not clone the EWS correctly?


after clean the adaptations i always had the error of TPS adaptations. it's needed do something else?
on stock ecu don't have any error.

Have you tried syncing the ews with inpa? Might be needed as it's a different ecu even if the vin matches up

if I do that i will lose the sync with my stock ECU, because that I make a clone to have a backup.

Im not sure so maybe someone else can confirm, but it's possible that the ews can only be synced to one ecu at a time, so if you have to use your backup ecu for whatever reason it maybe necessary to resync the ews

I think you need to resync it every time you change it, except it has the EWS delete file

I test today and the problem it's the EWS.

D1[209] EWS signal is wrong, EWS code implausible

resync EWS it's only press the button on INPA or I need to virginalize the file?
