[QUOTE="big23daddy, post: 5283391, member: 53648"] If your A/F was 12.3 the computer will pull up to 4 degrees timing out of the computer. It monitors Oil Temp, ITA 1 and ITA 2, Coolant Temp and Cylinder Head Temp. The Shelby ECU is very unique and also easy to tweak for extra hp numbers. 1 of the most important factors of the GT500 during dyno pulls is to monitor the timing during the pulls and also ITA 1/2 plus ECT....Oil temp, and Load, this will aid in the proper tuning of the GT500. You will be able graphed the timing modifiers vs. temps to see where the timing graph starts from once WOT is reached. On the flip side, the GT500's ECU has a target A/F of 12.0 or richer and will also add timing if it feels ITA, OIL Temps and ECT are in a safe levels which will add as much as 2/4 degrees...on the stock ecu if all other parameters haven't been touched. One of the first mistakes about the 5.4 4v engine is that it is very efficient and likes 11.2 to 11.4 A/F range instead of the 12.0 to 12.5 that some believe. Hope this helps you. BD [/QUOTE]
