Hey all, I am running a NA 99' 5.3 stock 411 PCM with a COMP cam 54-414-11 and a set of 8.1L 34lb injectors on a 255 LPH Holley pump in my 68 Chevelle. I have a Farm Service Station with E85 available 3 blocks from my house, otherwise I have to travel 20+ miles to fuel up with any non blended fuel. I am thinking about converting to a strictly E85 tune for convenience mainly. Right now on the logs I have, at WOT and 6200 RPM I am running 70% duty cycle on the injectors. I originally tuned with a Wide band o2 sensor in Lambda. Is it possible to tune this as is for E85? If so do I just flush out the old fuel and fill with E85 and redo the SD and MAF tuning? I have a tester to confirm the ethanol content and know some guys that run drag cars on E85 from this station who claim "its very clean E85 compared to most". Thanks in advance for any advice and have a great Wednesday!
