im a fan of the power commander owner of my tuning shop uses is it and its a great software. I havent personally used it yet but i did tune a harley using the screaming eagle software and im told there close to the same software.

This sounds like a terrible idea.


Anyway to the op. I used a Yoshimura box and a begi fmu to tune my bike and I got 160 on 3 psi. My build thread is on here somewhere. You can get a pretty good tune if you play with all three. Shoot for 11.5 to 11.7 afr in boost or you will be sorry, If you even think you might see the a/f go leaner than 12.0 in boost you better shut her down. These motors are extremely efficient and resist knock because of the heads. Thats why we can usually rune 6-7 psi on the bikes and still run the stock 12:1 ratio. Good luck with it.

LOL i know what you guys are thinking but bikes are a whole different animal.. my bikes ran at 16.3 WOT stock.

Adam Hopkins

No, its not really a different animal. Its still an internal combustion engine, and its still gasoline. I would not run over 13.5 to 1 on any all motor gasoline engine. I would say that the w/b you were using was off in some way. Either that or you could pull your plugs out and I bet that they are chalky white mixed with small signs of aluminum. Thats just me, what do I know?

Running leaner than stoich means you are not using all available air, and therefore not making best power. See also: lack of thermal cooling.

Try the FMU and see how the AFR's are? Post some pictures of this up!

havnt posted on this for a bit but give you guys an update. Progress is slow since been working close to 70 hours a week. Is what I did was take an old fuel rail out of one of my maxima motors made a new plenum and put them into it so added 4 185cc injectors so bike now has 8 injectors.(There went the 40mpg). I plan on using a power comander to controll the injectors once the money is available.

Adam Hopkins

Unless power commander has had some HUGE technological advancements that I do not know about then it will not have the adjust ability you are looking for. The PC I am familiar with are only able to modify the current injector pulse being used by a maximum of 20 percent. So at idle if your running 2% injector ducy cycle, you can only adjust the injector to a minimum of 1.6% or a max of 2.4%. If you have some questions shoot me your number via pm and I will call you.

thanks for the advice. I did find on some sight awhile back a injection multiblie controller. Was made to controll the extra injectors in the intake. Just to find it again. But that still don't help me controlling my timing.
