Making a E-85 only truck

Installed 425 pump with 750 cc injectors, new lines and pressure regulator. Need to tune the ecm. The AFR has learned from 10:1 to14.1:1 in 10 warmups cycles. E-85 I heard takes 12.6:1 AFR. Hp. Tuners gave me a stock tune to change. Even I see big Preformance problems with the stock tune. 10 sec. delay on PE.

 

Welcome from LA (Lower Alabama)! Are you asking a question? It sounds like an interesting project.

I think I have most of the problems solved. I want a fuel filter before the injector rails. One day I will get bad gas and I don’t want it to make big problems
