Its not really nec. The ecm in our bike willl adjust to maintain factory AF settings. If the bike did run for what ever reason excessively lean, IE leaking intake gasket then youd just pull a lean code. But swapping pipes your good.
I figured as much. Just thought I would make the learning process a little quicker by pulling the fuse. No biggie, I'll just ride it and let it learn. Not sure how much of a difference there will be between the 2 set of pipes to the ECM.
Theres prolly not much difference. Pulling that fuse just clears memory it doesnt do anything for ecm adjustments while driving. That will operate the same weather you pull that fuse or not. ride that biatch! lol
