I have a 2nd gen using the AP Engineering PFC and Im trying to figure out the lag time for the stock 550cc's. The FD's are .73 but Im not sure that holds true for the FC. I will be running 680cc primaries and 1000cc secondaries. Ive read the PFC manual and I understand the formula for changing the injector pulse timing. Any help is greatly appreciated.

Thanks
Chris

 

Not that important because when you AFR tune, it corrects the problem.

Here are some close standards.

550cc: 0.73msec
660cc: 0.75msec
850cc: 0.77msec
950cc: 0.80msec
