Hello guys, I don't know if my post should go in this section, I apologize in advance if not. I was a little bored at home because I am convalescing due to a recent unimportant surgery and I started analyzing the run logs that I had stored. Using the graphs that Dynojet WinPEP8 offers us, I have realized that although my motorcycle runs well, the graphs indicate that there is a certain imbalance in the richness of the air/fuel mixture. It seems that cylinder number 2 has excess fuel and, on the other hand, cylinder number 1 demands a little more fuel. Although the trim values are within the limits, (-60/60) I wonder if I should work accordingly by checking cylinder 2 vacuum leaks, dirty cylinder 1 injector or synchronization of the throttle bodies. Or it's just normal... although it doesn't seem that way to me.
What is your opinion?
Thanks in advance everyone.final fuel trim.jpgtotal trims.jpg

Anybody point me in the direction of V2 of PV3? They have a version 3. something out now on their website and I cannot find the V2 so that I may have more parameters. The V3 doesn't include all parameters discussed above unfortunately.

Thank You!

Well like the bank heist movie, I'm in! Thanks to pooh and xtine (Mark) who sent me the v2 of the pv3 and my fumbling around till I found what buttons I wasn't pushing correctly, I finally got to where I wanted. The v2 has quite a bit more than v3 available. After looking again at the hulk tune I decided that there really wasn't a whole lot to do, and the bike is running pretty good. I did notice there was a little miss rough running off idle when cracking open the throttle but the bike was at 140-150f temp and that might have contributed, otherwise it idles good. I think the steady spark table at idle contributes to a better idle quality vs. the stock tune where the low rpm spark moves around and confuses everything. Probably a lot of extra in v2 that will never be used but v2 includes some valuable parameters that are useable like engine decel.

And I will add I think there is power to be had via the spark table. At the higher rpm they drop the spark advance from 34 down to 27 range for some reason. But the thing runs so well and longevity is there to change it would be questionable.

Thanks to everyone and Mark
