For instance running E85 with a wideband setup for gasoline, when it is showing 14.7 you are actually at E85 stoich of 9.76 or lambda 1 all the way around. The gauge is just converting lambda 1 from the sensor to AFR so you have something relatable to read on the gauge. Your stock narrowband works the same way. AFR is just a way to read stoich for different fuels.

Either way all I needed to do is change the injector tables from stock to 60's then the 30% for e85. Ran the tank dry with the pump on and a fuel line off then filled with E85. Fired right up with no other changes, no pump, no rewire, no injector o-rings, not even a filter change, only took 20 minutes. After that I set the timing from stock to 22* and dropped from my 3.4" pulley to my 3.1" picked up probably 30 hp.
Excellent info and detail. Thanks!! Where exactly is the injector table?? Maybe I just have to jump back into the tune this evening and take a look. I also understand what you're saying about the wideband and AFRs, Lambda = 1, etc. That makes sense.. Does the computer always target lambda = 1, and then target a percentage of lambda based on what the PE table/mode is targeting? (when you are on the throttle enough to enter PE mode).
