Well idealy reprogrammed ECUs are the way to go, the problem is, getting a program that is for your exact application, and was tunned specifically for your car can be very expensive, assumung you can even find someone willing and knowledgable, with the software and hardware to do it.
As far as generic programs, with a stock car, they'll probably work fine, but when it comes to more heavily moded cars, there have just been too many variables changed, specific to that application, and the generic computers, no longer take into account the specific mos that have been made. In more simple terms, you can't stick a square peg in a round hole.
Hey Trey, is Kenji still working over in Tampa?????? If so, do you have a number for the shop he's at. I lost touch a long time ago when my friend Jesse stopped working with him. Thanks!!
Later!
