Ok, who can help with some basic tuning ? Just picked up a Pro Com ECU at a good price, and want to try it out. I’m not trying to turn this thing into a race machine, just trying to see if I can get a little more out of it than using a stock ECU and fuel programmer. Basically, looking to increase the rev limiter slightly (500 rpm) and lean it out slightly on the top end. I’d like to have a little more top end, and top end "kick", BUT definitely not trying to run this thing 90mph. I think I can figure out how to change the rev limiter. It seems pretty straight forward. What I don’t know is whether to decrease fuel at certain rpms v/s decrease fuel at a certain TPS voltage v/s change timing, etc, etc. And to what values to change them to. I do know enough not to make more than 1 change at a time, and very small increments.

I don’t have access to a dyno so this is strictly "advice tuning". But I do have access to fuel/air ratio gauge. I just need to weld in a bung for it. It’s a stock 08 800 with snorkels and RZR S exhaust. If this works decent, I might put my dual Trinity’s back on. If it doesn’t I’ll go back to the stock ECU and Dobeck controller.
