    Can I put 2014 GPEC2 Challenger Tune in 2014 GPEC2 Jeep PCM

    Hello,

    Installed 5.7L crate engine in a 2014 Jeep Wrangler 3.6L. Wanting to tune original GPEC2 PCM with Challenger Stock tune file. Both engines are for manual transmission vehicles. If this won't work, does anyone know the best PCM or tune for this?

    Well, I programmed it and no start! Got to thinking and decided it will not work because the 3.6L and 5.7L use different Reluctor Rings (Tone Ring) on the crankshaft. Purchased a 2014 Challenger ECM (PCM) with a manual transmission (Auto Trans has diff O.S.). Changed VIN using Autel MS906TS and changed Comm. values using Editor and it started up. On the road now! The major pain with the Jeep JK swap was exhaust and changing all the engine wiring from firewall to Left front fender mount.
