Jtec jeep turbo e85 tune

I have a 96 Cherokee jtec ecm. I have been turbod now for about 6 months. I had to swap my motor as the old one was tired. I had everything pretty much dialed in. It is running 10lbs of boost.

I have a 340lph fuel pump, and 36lb injectors. Unfortunately I?m guessing I might be on the max side of my injectors with e85, if not then I will be borderline would be my guess so I might have to increase my injector size. I figured I would give it a shot as I have no idea how much power the jeep is actually making. I have never tuned e85 stuff so I?m not entirely sure what I?m doing exactly.

I had figured that theoretically I should be able to increase my fueling by 30% and add some timing to get an e85 tune since I?m pretty much dialed in. I am rich in a few areas in the cruising range that I need to fine tune but other than that I should be there.

What target afr should I be looking for with e85?
