Ok, I got to have some questions answered here
Does anybody have the stock a/f ratio chart on a dyno sheet or what have you. Yamaha is notorious for running their bikes very rich at idle to very lean at top end. You just cant fix it without a PC aftermarket piggybacked on the ecu. Reboot or not it just doesn't have enough parameter area to cover the addition of a K&N filter or an exhaust.
So Honda has 3D mapping. Ok I looked it up and it doesn't say how much it will repair in the a/f mixture, so how much will it repair?
Plus, how would you know if you are or not in the stoic area of a/f mix ? Wouldn't one need a sniffer done on a dyno throughout the rev range ?
Not trying to stir the pot, just curious of the a/f mix across the board after adding a very breathable air filter and exhaust, is it realy safe, has anybody an a/f map so I can see it?
Is this ecu reprogrammable by a Honda Rep ?
Extremely concerned here with this 20k motor.
