Hellcat E85 Tuning

[bad383ta]

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.

Don't change the stoich leave it stock, it works just fine.

What injectors are you using? Post the tune file in question, for more help

I was wondernig if anyone had actually see the tuning schools NN stuff- I had a little bit of a learning curve attacking the NN off side of it myself- Did they whole VE over- pretty touchy on the hellcat, more so than any other Mopar Ive done so far - I dont have my files infront of me but I Would love to see how yours looks compared to mine - we stopped at 860 torque and on that pull we shut down at 5500 so I didnt get a high hP reading - 806 hp .

On no FFV ( ethanol sensor cars ) I always leave the commanded AFs pretty much stock - theres so many fuel changing values I find that I always overlook something -

Can you richen up the fuel mixture enough with the stock injectors if the hellcat was stock?
