I'm trying to fit a EMU to a BMW V8 M62 engine and have experienced some problems. Maybe some here has som ideas ?
First when I received the car the ECU was already fittet, by the owner by my instructions.
The ECU was programmed with FW 1.016 and I updated it to 1.100 - after that update all data and breakpoints was corrupted, so I had to do them all
We are running 8 injectors in 4 pairs (high Z's) and measured resistance on every fuel channel to 6 ohms.
The 8 COP's are driven by 2 x VAG 4 channel drivers in a Wasted spark configuration.
The injectors are 850cc's at 3 bar fuel pressure we are using standard BMW temp sensors on CLT and IAT
I have calibrated the trigger setup and have fired the engine up. The engine idles smoothly.
Problem is there is absolutely no connection between VE map / ACC Enrichment and the dutycycle on the injectors.
I can have the engine idle with 1.3 ms DC but opening throttle does not affect the dc (regardles og setting in ACC enrichment or in VE)
Having the car idling an changing VE to 10% or to 400% does nothing at all.
(it is not caused by a mapswitch also checked on VE2)
Included is my mapping (very coarse, just because of all my testing)
Can anybody see where the fault is ?
Thanks in advance !
