Put in a new exhaust a while back, and it just occurred to me that I never reset the ecu. I know that you have to unplug the negative terminal for a while, but is there an ideal time to leave it unplugged? I googled it and couldn't get a definitive answer.

 

You don't have to reset the ecu man or disconect the battery as your ecu will relearn on its own. I would suggest you get a tune though as it will alow you to get the most out of your mods.
