Individual cylinder fuel trim

Post by 04silverado6.0 »

Has anyone found the table to adjust individual cylinder fueling on a p01? I know it is present in the p59 but never seen it defined for any p01 os.

Are you talking about the "Injector Trim Factor" table?

I compared the 7603 P59 OS to the 2156 P01 OS in HEX. They have the same parameters in the same order, and it appears that the P01 has all the same parameters but skips the "Injector Trim Factor" table. I tried searching for the HEX string that is present in the P59 but it is not anywhere I could find it. In my opinion, that table is not present in the P01 2156 OS.

I appreciate the reply. I guess that is a good reason to swap to the p59 on power adder cars.
