So im here in iraq and i have lots of time on my hands, and i was thinking...

i know this has been brought up before, but not much, if anything came out of it that i could find. Running 2 pcm's in the same car (07 SS S/C), not at the same time, obviously. If you had a Y connector of some sort so that you can plug them both in and then switch between the two with a switch. The only problem i see right now, other than finding/fabricating the Y connector is how to switch between the 2 pcm's. I looked at the pin out that was linked in another thread, but there isn't a power wire or anything like that, at least not that i saw. So my question is, how could it be done? Any help would be appreciated.

 

Not worth it. Just keep the 2nd PCM in the Glovebox and switch them out when needed.

 

Not what i was hoping for, but that was what i was expecting. Thanks

 

Youd have to shut the car off anyways. Could you imagine if you accidentally switched PCMs mid-drive?

 

anyways, switching out PCM's only takes like a minute, disconnecting your battery before doing it would take longer than just swapping them.

 

You could mount them both, splice the wires, then run a seperate switch for each wire into the car, your interior would look like Knight Rider.

It would take you 2 minutes of flipping switches to change over,
