Hey Jason,

do you have some '01-'05 good crank vs cam signal scopes with the cam most advanced and most retarded.

I want to see where the cam sync teeth move vs the crank ones and is it possible by cutting 2 of the 3 teeth from the cam mounted wheel (leaving it with just one tooth) make it work along a 12 tooth crank wheel (the single cam tooth not crossing over a crank tooth)

Warning

Be warned that if you are >= 20* (crank degrees) retarded on the intake cam (mistimed timing belt), the AEM won't be able to sync.

If the cam is advanced even 1 tooth, it will lose sync when you go to full advance on the VVT.

Where coil output #1 goes to coils that fire cyls 1,4
coil output #2 goes to coils that fire cyls 2,3
Question.
What would the injection settings be for a setup with batch fuel?

I am just trying to get running with my current wiring. I will do the sequential wiring later when i have time to redo the fuel map.

To further this: my settings for fuel are:
inj tooth #02 @ 2.00
inj tooth #10 @ 2.00


This would squirt all 4 injectors at the same time?

Just going from the cal i was working off last year...
