BMW M3 E36
(previously tuned by DA motorsport - unsuccesful)
Files:
curent MSQ and log a few engine crashes at 2500 rpm hence the 3.01ms dwell, at 1ms runs but i doubt the spark is good at 1.2bar boost...
- Wait for the lambda to heat up before datalogging to tell us more.
- I would run 1.0.x firmware on this engine.
- Update your story below to be more comprehensive, remove information that has become irrelevant.
- Did your problem exist both with 1.0.73 and 1.1.27? Post MSQ from both situations.
Progress report:
Engine running, no trigger errors, occasional missfire, very rough idle, BUT
At 2500rpm it just cuts the fuel, or spark (could not establish whitch one) and just dies (does not respond to gas pedal at all.
Today i upgraded it to 1.1.27 (dont know why) and started the config from the beginning, including the VE and Spark tables...
Now it manages to reach 3700rpm and again just drop dead.
[SOLVED] coil charging time was too long, shortened and engine now runs fine to the redline...
Also i have issues with terminal communication, could not manage to get "normal" respond to mll command, just some unrecognizable raw data )}}}}}@@@@ etc... [SOLVED] seems that terminal commands are case sensitive :(
NEW problem, after some tests with running engine, map sensor reading started to act funny, it reads 11kpa and if gas peddal pushed it reads 247kpa at WOT.
Did we fry something or it is just playing dead again ?
[solved] Alpha-N was active by mistake...
i am going to try with another v3.3 board, and 1.0.73 :)
[no need for that now]
Test drive ended with fried exhaust manifold gasket. but after several repeated 300km/h runs...
New problem is that engine would not rev over 2500rpm when it crashes, with anything else than 1ms in dwell time :( dont know the answer for that since the coils are standard m3 cop-s that require a little longer dwell...
firmware is still 1.1.27beta4 !
Engine:
- S50 3.2l inline six
- CP Pistons 87mm 8,5:1
- Garrett GT3582R
- stock cams, vanos removed
- DA exhaust manifold, M50 intake manifold
Genboard v3.3 1.1.26 firmware
- 60-2 crank wheel, VR sensor
- hall camsync not used
- 1000cc rochester injectors (lowZ series resistors 30v flyback)
- 4bar map
- Dual out COP ignition
Special hanks to Jason Voytilla for His msq file :) it helped me start it... [and reach 300km/h]
