I was working with Greg and a protege of his on a Ford. We got into the discussion of fuel and E content. I started doing some research and found some basic formulas. Then I put them into action on my daily driver. WOW! It was like night and day. Next I started adjusting for it on some other car. Same results.

I still need to figure out a Max Power formula for E content. It looks to be a curve, but I keep missing it. Maybe some of the known figures are wrong.

also if Stoich is 9.0078 or 1.000 Lambda for E100 the WOT EQ ratio need to be 1.27 or .792 lambda.

E0 Stoich is 14.68 or 1.000 lambda and WOT 12.7 and a EQ ratio of 1.15639 or .86476 Lambda

I currently have been checking the fuel content and have found it to be 10% in my area. I switched the Target AFR to 14.4 just as a test and the target WOT EQ ratio to 1.17 and the car runs great. I am still doing some testing.

BTW thanks again Greg
