New Demon center stack $570 plus shipping.
You would have to get the car programmed to use it but yes you could use it for fuel swaps between regular fuel and E85. The Demon has the stock PCM and the crate performance PCM once it's installed you don't have swap back and forth you can use 93 octane and race fuel just hit the high octane button when you add the race fuel.I'm curious..... What does changing a regular tuned hellcat to this stack actually do? Could you use the fuel button to swap tunes to e85 just as with a demon, of course after having your PCM tuned to accept it, or is there more involved getting it to work? The Demon uses two different PCM's to swap back and forth with on different fuels, doesn't it? I'm unfamiliar on if the stock PCM can be used like a nice standalone and can hold separate tunes to swap between.
