I think that before singing the praises of something like this, you should make sure you've already used it yourself. Yes, I agree that ECU+ is a good tool, and I even have a local friend who rips it down the 1/4-mile at every opportunity (Ivan_C), but it is a self-tuning device. Like any self-tuning device, there is inherent danger, and you have to do a lot of research so that you understand AFRs, timing, boost, EGTs, detonation, and how all of that inter-relates. Of course, we aren't all born with that knowledge, and you certainly can learn all that, but it's not something you just slap in and go on your merry way.

 

Fair enough, I'm just offering possible alternatives, that's all.
