Hi guys
Having a massive problem here with an engine setup using ID850 injectors on an early model e38 pcm and getting around the 63lb injector coded limit
Have tried tuning the car numerous ways, but run into the same hurdle regardless
The car will tune up, drive and behave perfectly at all times EXCEPT initial cold start and post start enrichment
IF you can get the car started and to stay alive past the first 30 seconds or so she is fine - but this first part is the problem. Warm, or even semi warm she is perfect
My latest attempt has involved trying the "stoich" trick, but doubling stoic far and halving injector flow rate. Also tried, on advice from hptau, o try tuning it and just "wear" the injector coded limit in the ve table - which surprisingly worked out ok despite the same cold start issue I'm having using other methods
One of the biggest issues seems noticed when scanning is that getting the car to kick and fire isn't the big issue, but once she does she will want to die. If you tap the throttle etc to try to keep her alive, the injection time will max out to some ridiculous number like 200-300ms +, flood the thing, and kill the car
The car only really dies when this happens, but for the life of me can't work out why it is doing it
Mods are
20007 Australian VE CLUBSPORT
LSX376 crate engine
233/238 lsa 114 camshaft
YELLA TERRA 3.4L whipple supercharger kit
upgraded fuel pump (fuel system is still return less)
ID850 injectors
a few variations of tune file and log of the injection time going spastic post crank attached
any thoughts here guys?
