My 03 Fatboy FLSTSI idles a bit high. I have a power commmander USB on it but dont see where I can adjust idle speed. Any help would be appreciated

 

Did this just start or did you just install the PCIII? Did you calibrate the throttle on the PCIII? Has the bike been dyno'd?

If it was running fine for a long time in all seasons and just started, then you may need to check the Engine Temperature Senor or the Intake Air Temperature sensor (I'm not sure that '03's have these).

If you didn't do the PCIII installation then I would assume that the throttle was calibrated.

Has the bike been dyno'd? If not, you may need to adjust the air/fuel ratio in the lower rpm ranges, especially if the idle is always high, not just some of the time.

It has always been slightly high, but since installing the PCiii USB it seems a bit higher. It has not been dyno'd but I have the feeling for the fine tuning it is better sent to a Tuning shop to avaoid damage.
Thanks for your reply

 

Have you zero'd the throttle since the commander was installed?
