Drivetrain Malfunction-Stalling
Hello all been having an issue with my M235 stalling when i first start the car and after a long sprinted drive. Also i have a-lot of gurgles and pops when in comfort mode (this only used to happen in sport). Terry suggested that i may have a 02 sensor problem, not knowing how flashing the cat readiness affects the 02 sensors is one of my questions. (mods and codes Below logs also linked) Thought it was a fuel rail issue so sensor was replaced as well.
Jb4 EWG connector Enzo Tune Catless DP Chargpipe Hd intercooler Intake NGK 97506 2 step colder plugs gapped to 0.018 Cold Start codded out Readiness codded Codes: 102001 119002 101F01 And 102001 101F01 121530 120408 Logs: Map 5 https://datazap.me/u/wahooooman/map2...log=0&data=1-4 Map 2 : https://datazap.me/u/wahooooman/map2...ata=1-4&mark=1 Any clarification or help would br greatly appreciated Thanks

I'm running BM3 OTS tune with the cold start delete and haven't had any stalling problems , although it runs like crap when it is cold out for about 30 seconds. That should affect the O2 sensors.
Also curious why you are running a JB4 on top of the Enzo tune? Is this an older Enzo tune? Enzo supports BM3 now. With your map 2 log it doesn't look like the JB4 is adding anything. Your map 5 log does have higher targets but you are not hitting them. Note that with the latest JB4 firmware you have to set the duty bias to 50 or you will underboost on absolute maps per the instructions on N54 tech. Do you have the issues running map 0 or with the JB4 disconnected completely?

So far I have the issue with Jb4 on map 0, I will uninstall today and see if I have any issues, but sometimes I need to drive it for a day or two before it happens. what does happen every-time though is the struggle to start and a little RPM fluctuation on idle. I guess my question is i know what the 02 sensors do but does the flash do anything to the normal operating procedure. If i had a bad 02 the car would run like crap even with the flash as it is still looking at mixtures ? sorry bit of a newb with this flash business. Thanks for your help !

If the idle problem remains, you might check with Enzo. It could be he has to adjust something in the idle tables. At any rate it shouldn't be stalling unless you have cold start delete and it is actually very cold. As for the codes are any of these sensor codes? Your AFR values looked OK and I would think these would be messed up if the sensor is bad.

did you have under 1/4 tank of gas and get on it?
This will throw a CEL drivetrain every time for me on track.

So I have been filling my car full since I read a post about this a while ago, I can say though if I have less than 1/4 and go over bumps I do get the same issue.

I have been experiencing the same issue although I have no tunes or chips installed. it only happens when it is hot outside >85 degrees. The warnings have intermittently been: Lighting System malfunction, Cruise control malfunction, Drivetrain malfunction, and Chassis malfunction. Only the last 2 have caused the stalling.

how is your idle and do you smell gasoline on idle? Gas not exaust.
Might aswell just add this to anyone reading. Had the same issue. Car stuttered occasionally and hesitated on cold starts. Once it almost didnt fire up and the light up the DM. After restart it disappeared. Did a couple WOT nothing strange, car pulls hard. Read codes. Nothing. Then I started to notice hard idle and gas smell on idle. Took it to dealer. Valvetronic harness change. Then all codes appeared and pointed to valvetronic servo motor. After they changed that car didnt send codes but new vaules couldnt be coded into the valvetronic ECU(or ecu in valvetronic section). Then they changed the eccentric cam. And now car took in the new values, idles perfect and no stalling. Point is, there could be hard malfunction that cant be read by codes / not saying this is your case. Just a heads up.

For some reason the malfunction stopped once Duty Bias was changed. No more Malfunction no more hard start/Stalling.
