Jared's 2015 Challenger Hellcat Build

[Jroc]

Time to update this thread as I've been posting a bunch of stuff in a different thread I had going.

The car is back together and running on the new setup. Since we needed to replace all the harnesses, and I wanted the best of the best factory features that would be available on the car I ordered Demon 170 harnesses and threw those in. With that of course I had to do all new modules, BCM, PCM, etc, even down to door modules and wiring harnesses due to changes between 2015 and 2023. Using a wrecked Demon 170 VIN we programmed the PCM with a Demon 170 calibration, programmed the BCM and everything else to match, and put in a Demon 170 transmission so the car would have the correct TCM. There are a few things I still need to do like buy all new AC/Lines, Redeye/Demon AC Compressor, and the chiller to have functioning AC and Chiller system but we will get that done over the winter. The car now has all Demon 170 features, such as flex fuel capability, transbrake 2.0, user programmable launch profiles, etc. By all accounts it is a full Demon 170 swap.

The new 411 is running great, the car is being tuned by Z and he's killing it on the tune. I had the car out at the track last weekend and couldn't get the thing to hook for the first 330 feet but ended up going 9.42 at 151 MPH which while not representative of the cars capability I am extremely happy with for our initial shakedown trip.

Next up is to upgrade the fuel system since we ran out of pump trying to run full E85 at the track, I need to decide between sticking with a returnless system or move to a return style fuel system.
