Is it possible to socket some sort of Y into the pcm then have 2 chips in order to store 2 pcm programs on the car, and have the ability to switch them over when the car is off?

This would be badass if it could be done, have a daily driven program and a program for race gas with more timing, boost, etc....

Lemme know guys!!!!

 

I dont see why you would want to do this when you can just have reprogram it for racegas, then after the track, put pump back in, and take another 3 minutes to reprogram. Or am I missing the point

 

Is it possible? I suppose it is possible, but the difficultly in doing so would be not worth it. Since you would actually need to have two Y sockets and 4 chips (there are 2 FLASH chips on the PCM) and then something to switch between chips made so you can easily change them (from the inside of the car, I'm assuming). A lot of work, if you ask me, and it would take a lot of custom work. Just reprogram the PCM when you need to, it only takes 3 to 5 minutes to switch programs.
