sequential fuel delivery for 8 cylinder Audi engine
firing order: 1-5-4-8-6-3-7-2
Bosch fuel pump in the 80/90 is the same part# as A8 and I think fuel pressure is around 2.5 bar (?)
Injectors are stock A8 units with the idle vacuum port plugged but I plan to upgrade to 400cc Delphi in the near future
Did you flow them? My A8 injectors were 200cc@4bar.
that is awful, no wonder they run out of steam with an exhaust and intake :P
Ok, here are the latest panels from megatune that result in the motor starting and idling for a few seconds. Any throttle input kills it and the idle basically just tapers down to nothing after starting... So like I guess the fuel delivery is not happening.
I am going to go hog wild on the megatune site to figure these out but feel free to add your ideas:
This shouldn't matter and is really a wild guess, but change it anyway, set injpwmDC (%) to 100%.
After doing so and making sure that it has been saved in the ECU you need to go to the terminal and type Manmcd, in the output you'll have to find the injpwm=FF (what you just chnaged) and verify that it's really says FF. The real reason of the excercise is to check that the injpwmt=FF that should be right above it also says FF.
