Tried to reset my tps. The idle set cable does not contact the butterfly stop until it is screwed all the way tight against the spring that is supposed to mantain tension on the cable, as such I can only achieve about 2.4 volts on ecmspy without turning the throttle manually. I need some help here guys, the throttle and idle cables appear to be correctly adjusted.

Difficult to say without pics but I was attempting to reset mine once and the flex spring had broken the ziptie holding it and worked it's way in between the frame so that it was binding. Needless to say I cussed at the friggin thing for half an hour before I found the problem. GL

try this as your situation is quite common: remove air box cover and airbox lid and filter exposing base plate and throttle body butterfly. examine it with flashlight for any crud, grit, or debris. spray some quality carb cleaner down around the butterfly and areas where it meets interior throttle body. you want it sparkling clean. then replace filter element, box lid, and box cover. now reconnect ecmspy and activate, get bike talking to computer properly. give the front most throttle cable (the puller cable) a bit of slack, leave the rear most cable (return safety cable) alone. have the idle speed screw turned out fully but not so far that it comes out of its threaded post. now blip the throttle several times and let the butterfly more or less slam fully shut. that should give you a reading of 0. keep playing with it until you achieve 0 but if following these steps you should. then do the tps reset procedure. post back if that works or not.
I took my bike to New Castle Harley/Buell and the mechanic ther was ablew to sort out my problem, The throttle was not snapping back closed. The culprit was a zip-tie pinching the cables. cut the offender and reset TPS. quick, efficient and honest highly recommended.
