Ok think i might understand this?

the CPS is on the exhaust lobe on bank 2 is used as the trigger right?


0 starts the exhaust stroke and its measured in degrees on a circle, so if I had cams withs 334 degrees of exhaust duration, id just punch 334 in the graph?

No. The value is where the injector finishes firing at.

But no need in wasting your time with it. You simply set the entire table to 500 and your done.

Ok, setting this to 500 across the board helped.


However, it did not eradicate it.


Could you walk me a little further here so I can see if fine tuning it helps that last little 10%?


If my cams had 262 degrees of advertised exhaust duration, what would I punch into this table to match that specifically?

There is no fine tuning you simply just set it to 500 and done.

If you have issues its elsewhere not injection timing.

This has worked for me in the past on Injector Delay

Example Increase inj timing to % of cam overlap vs stock cam.
NEW LIFT * OLD LIFT * 100 = FACTOR DIFFERENCE
CURRENT DELAY VALUE + FACTOR DIFFERENCE = NEW BASE VALUE.

This should give you a good starting point to allow idle control with a larger camshaft.

Im running a megasquirt nowadays, but spend a lot of time chasing after the eec v setup lol.


Could anyone happen to tell me how the ford pcm times the injector pules?


and by that I mean do the injectors come on at the beginning, middle, or end of the CPS sine wave?

the injector timing could be set for either the start edge or leading edge of the signal

typically you set the injector timing to 500 so the pulse ends at 500 degree.
