PCV Tune With M4 GP Slip on
My friend currently got his 2009 zx6r dyno tuned and sent me a screenshot of his map (unfortunately only from 0-7500rpms). I have noticed that his map has a lot of fuel cuts, making it run more lean that it was with the off the shelf map for his bike from Dyno Jet. I took a quick look at the off the shelf Dyno Jet map and a lot of the 0% fuel has been leaned out to -3% fuel in the lower RPM range.
Not sure if the person who tuned his bike knew what he was doing, or is his bike was running so rich, the fuel needed to be cut in the lower rpms.
He said his bike does run much better, and he is getting better fuel economy. But the map thatís on his bike now is just so much different than the off the shelf map from Dyno JetÖ.super leaned out in certain spots. The thing that concerns me is that alot of the time when riding in town/city you only use 2%-5% of the throttle at 4000-6000 rpms...and its leaned out throughout the majority of that range, where the off the shelf dyno jet map is zero'd out. I'd just hate to see anything happen to his bike...I know running rich is better than lean, but to find the happy medium is what we all want.
What do you guys think? I will ask him for another screenshot of the #ís from 7500rpm and up.
He's not an active member on any forums and asked me if I could ask the zx6r community as neither of us really know too much about tuning bikes.
