I've been using the Powerjection PIII for three years and I saw the Atomic at SEMA last year. I wasn't too impressed talking with the engineer's on what it can do. It's a self learn no operator input system. So, if you need to tweak it, good luck. The PIII uses a laptop IF you want to tweak (I advise that) or you can let it learn yourself. It also uses a wideband O2 sensor for tuning.

From what I know and see, both units are easy to connect to an existing system. Biggest thing is getting your fuel pump installed if you have a carburator now. I run an in-tank pump (EFI is pusher, not puller).

As for the CPU in the TB, not a problem. The fuel acutally cools the CPU while passing by. My CPU runs about 100-120 degrees while running. Oh, I can obtain data from my PIII system and not sure if the Atomic can do that. If it can, how would you get it?
