Power Commander V
I have not been a fan of the earlier Power Commander products. Basically because of it's tuning limitations. Click Here for more information.
I just completed factory training from Dynojet, on the Power Commander V. I was very impressed! The Power Commander can now read the data of the bike's computer and now has the capability to manipulate the AFR in areas that they couldn't before on the earlier PCs.
You can now adjust cold start fuel, cold running fuel, Acceleration and decelleration fuel, along with the usual front and rear VE fuel and Timing tables. It also has the capibility to store two maps which can be changed on the fly with an externally mounted switch. The will work great with nitrous applications.
The PC 5 is now much easier and quicker to tune with more accurate results than before.
The only thing that I don't like about the PCV, is that you have to disconnect the O2 sensors (which can cause less fuel mileage) and when you increase the rev limiter, the bike's tach will still only go to 5,300 RPM.
