I was told by the people at Dynojet/Power Commander that the PCIII does not, and can not, change settings below 20% throttle openings.

That's right, I heard the same thing, because of the stock ECU being closed loop, only with the open loop DP ECU can the PCIII map the entire RPM range. Aloha Alex

This was one thing that I could never understand. Why someone would pay $500 plus for the DP chip, then almost the same for a PC III just to run a pipe. Some of them even go as far as adding the Fatduc. So they have somewhere around $3,000 for a few extra HP. Now don't get me wrong, I am all about getting the most power from a motorized vehicle but this is crazy.

I think I would rather go the slip on, PC III route before throwing crazy amounts of cash at something just to kill my MPG because I am running super rich.

What is the real reason that people feel the need to run the PC III and the DP chip together? Are they getting bad info from the dealership or just the web? On just about every other bike out there all you need is a PC III a few runs on the dyno. This will get you optimum power and you are good to go. Why is it not this easy for us?

What I learned from some of our Forum members is that the stock ECU starts off as a closed loop ECU and then will change into a open ECU in the higher RPM ranges, The PCIII cannot map the stock ECU when it is in the closed loop mode, but will be able to map the stock after about the 25% mark, and for most people that will be just fine. The DP ECU is a open loop ECU so the entire RPM range can be mapped. Hope this helped, Aloha Alex
