I have noticed that there are quite a few different EFI controllers for the Raptor 700. Which one is the best Powercommander 111, Trinity Stage 4, Doebeck, or some other? Also where can you order the best one?

 

Dynojet (makers of the powercommander) They've been more involed of tuning EFI for Motorcycles and ATV's longer then anyone. Their reputation is second to none. Just my oppinion (but a wrench who's used them for a long time, even before EFI) Later, Putt

 

I feel it's too early to tell, PCIII is more advanced and gives you more options, the rest pretty much do the same thing, give you the option to increase or decrease fuel in three seperate areas of throttle, I don't think one is really going to be better than any other.

 

I went with the Dobeck

 

Stock ECU doesn't compensate for even a filter change, don't change anything until you get an aftermarket controller.

 

you guys better listen to Larry!
