Does anybody know what the stock 256.76 number in the power enrichment blend rate represents? I want to be able to set the air fuel ratio the the computer tries to get too to be 13.5:1. I have been programming the computer with the O2 sensors unplugged so that I do not get the computer trying to adjust automatically.
Please let me know what you have done to get your 4.0 to run in the 13.5:1 ratio?
