resetting ECU

i wouldnt think so.. all it does is resets its mapping.. so technically no, but i wouldnt sudjest doing it alot, because there should be no reason too in the first place. I doubt it would do anything though

I posted this in the general discussions thread. It contains the link to the pinouts.

Any comments especially to my question. I need more feedback before doing it.
