Title: EFI controled timing
Post by: flyinlow on September 25, 2018, 05:59:04 PM
Switched my Fitech injected 440 to ECU controlled timing. For those who have done that, what numbers did you input for:


1100RPM     45PKA______            95KPA______

3000RPM     45KPA______            95KPA______


6000RPM     45KPA_______          95KPA______


My old distributor was 24* idle   36* @2500rpm  plus 8* vacuum above 10" vacuum

does +/- at 6000 rpm help?

Thanks Charlie,

I was thinking of numbers about what you  suggested. I guess the only way to check the "centrifugal advance " is to drive WOT and data log it? Just revving it up with no load gives me the 45 kpa. numbers. (Centrifugal + vacuum)

If I temporarily  set the 45 kpa. numbers to match the 95 kpa. numbers (WOT) . Inputting  24* @1100rpm, 36* @ 3000 rpm, and 36* @6000 rpm. I should be able to confirm this with a timing light  :shruggy:

yes ,you might change the others above & below 45 kpa also, & you should be able to match it with a timing light, you might have to move the dist for it to match. Holley & FAST have a place in the software to correct the timing offset, I am not sure about Fitech.
