From: Georgia

Car: 77 El Camino

Engine: 355 Converting to TPI

Transmission: Converting to 4L60/4L60E

These are the same ones that Painless is using in their Perfect System. They had posted back this spring on another web site, that they would have a second phase of system which would allow the user to reprogram the ecm. It was suppose to be out sometime this fall. I read last night that they are running way behind with the LS1

Right now I don't know of a prog that can reprogram them. Too bad, I believe that they could become a good all around ecm for most styles of EFI.
