I have tuned many a hellcat and many Hemi vehicles on E85 but never a combination of both. Today I decided to try some E85 in an 840 rwhp 15 kitty. I changed the FA stoich to .1027 for E85 and started the car. To my surprise it is pulling out 25-30% fuel and the Dyno wide band is reading 18-20 to 1. So its pulling lots of fuel when its running really lean. In all my other E85 Hemi tunes I have disabled the Neural Network and worked the VE. I left the Neural Network on with the kitty and I assume this is what is playing havoc with my fun. I purchased the tuning school hellcat 1 and 2 a few years back and remembered they left NN on with E85. However I have not watched it in a year or more and its not listed in my account online, they are going to fix the problem but I wont have it until Monday when they open back up. So I placed the stoich back to stock and adjusted the injectors off 30% just to get the car running good and movable for now and the fuel trims are within 5%. So what went so bad when I adjusted the stoich.
