Fi2000R settings on my V-Star 950
I know this has kind of been discussed to death, but I'm trying to get the best settings on my Fi2000R O2 for the Caliente Rocket. I've got stock intake and Cobra Speedster Longs.
I did some searching here on this forum and some other sites. Basically what I learned is that there's no magic settings that work for everyone, and that I need to experiment. I've been poking around with my settings a little bit, but sort of random and without much thought into it. Right now I'm at 2.5/7/7. Idle and cruise are fine all the way up to highway speeds, moderate acceleration is usually okay, but sometimes bogs a little bit. But when I really pop the throttle open, it bogs and actually loses power a little. Doesn't stall or anything, just obviously not the right mixture. I'm thinking maybe I'm running too rich, since I don't have a BAK yet.
What I want to do is have some kind of systematic approach to make sure I get the best mixture (or close enough to it). What's the best way to do that? Other than shell out a bunch of coin for a dyno run. Start with the settings high and back them off? Start with the settings low and work my way up?
I'm sure this will take some trial and error, but that's okay as long as I'm not blindly turning pots and hoping for the best. I know this module is supposed to be similar to tuning a carburetor, where green=PMS, yellow=needle jet and red=main, so if any of you carb guys have advice, feel free to chime in.
