Viper,
I am an Electrical Engineer and an Arduino enthusiast. I would be happy to help in any way I can, as I only have one key for my Crossfire and am deathly afraid of losing it haha. I don't have ECM programming equipment - unless the USB-OBDII communications cable provided by Eurocharged counts...
From my perspective, the highest value of this product would be a bypass of the immobilizer so that we could use any keys that fit, combined with a simpler "kill switch" that we could hide somewhere to replace the fancy immobilizer.
