PC III Open Throttle Calibration : V-Twin Forum: Harley Davidson Forums

richjbutler · 09-13-2009, 01:21 PM

I'm still going over the install instructions for the PC and was hoping for some insight on the throttle position calibration. For the fly by wire bikes dynojet says the open calibration can only be done with the engine above 3K rpm. Does this mean hold the throttle full open with the engine running and then make the software adjustments?

you will need to apply a load, such as with a dyno with brake. you could collect data with a twin scan 2 plus and use that data to correct the PC tables also.

BTW, thank you for your service!

You really should not need to adjust anything but closed throttle. It is far more critical to have this set dead on than WOT. If the WOT calibration is off even 5% you will not feel the difference. If the closed throttle is off that much it makes a huge difference. Just set closed and you will be fine.
