Can someone please school a dumb carburetor guy? There is a VEC, SCT, and PCM reflash. What the heck do they all do and which is the best? Thanks.:dontknow:
I'm a little confused...

Good question,i was too ashamed to ask
They all do the same things (Basically).
They allow the programmer to specify shift points, A/F mixture at different throttle positions/RPMs, regulate the fan on the radiator, and some more fancy stuff. All of the changes are made to the firmware on the PCM/ECM.
The difference is that the VEC and the SCT can change the program anytime by hooking it up to the ECM, the PCM/ECM Flash is a "permanent" program change. (Meaning that you have to send the PCM back to the programmer if you want to change the flash.)
That's it on a basic level.

diffrence is, if your going forced induction at a later date, get the vec3 save you money in the long run.
