vw 1.8t 20v sequential injection

Post by maxf31 »

Running a p8pro with vag cop.
I don't know how to properly setup the cam sensor angle position.

Engine don't start, I see fire only in cyl. 2 and 4.

any help would be great !

thanks

I suggest starting initially in batch fire mode to sort any issues out first. Select twin spark mode in general engine settings and sequential injection off.

Batch fire mode didn't worked. my wiring is made to run sequential inj and individual cop...

It started once tonight with the following settings:

I'm getting closer but I'm sure it's still not right.
Someone must know this one !

coil + Injector wiring looks like you need to use op1,2 and 5,6 so just swap the ecu connectors over to test in batch mode with twin spark.
Dont get hung up on sequential right now, just get it running,

Sequential doesn't make much odds anyway unless you want to save a little fuel on cruse.

Got it working !
I had the firing order messed up and forgot to double the cam sensor position since it's on a 720 degree range...

Injector angle at -300deg
Cam position sensor at -90 deg

I'll double check theses settings with a scope but the engine seems the run well!

Thanks
