is it possible that a tps would function as the book says it should and still be bad?runs fine unplugged.........yeh its been reset and have checked voltage while twisting throtle and its within range 0.5-1.5 volts closed throttle and 3.9-4.9 volts wide open and no voltage spikes in between. | ||

What sort of trouble are you having? | ||

it is running rough and popping through the injection i unplug the tps and it runs normal until i twist the throttle about half way...................thanks in advance | ||

What do you mean by "popping through the injection"? And so what happens when you turn the throttle half way?? And finally, are you checking the voltages via ECMSPY or regular voltmeter? The main difference is the knowledge of knowing whether or not the ECM is working properly. | ||

I presume that is the spy readings, Ok Tps appears ok what else has been changed? I take Popping through the injecton to mean spitting back out of the intake lean mixture ( filter off ) skewed sensor etc please post the following If you can at idle, air temp indication the actual air temp head temp tps position in %, deg and volts idle speed STOP MOTOR what are the % deg and volts at FULL THROTTLE ( on the stop ) what condition is the fuel and filter what condition is the vent check the cable adjust and stop adjust } | ||

Dog, this is the same guy with the timing tread, he didn't "run in" the new settings on a new ECM. When I did mine Al told me I had to ride the bike for 15-20 miles @ 30-35 mph to "run in" the new ECM. And he's using ECMSpy without a dyno. | ||

Fun I reset the TPS on my race ecm and took it out and rode it too. it was wonky at first too. I wonder if SA just reset the AFV and the TPS or if he went mucking about. whats wierd is the unplug the tps and it runs ok to 1/2 throttle, need to prove that the TPS is functioning and reasonabley close to correct. then other tests to see what may be amiss my 02 zero it and like you suggest ride it for a while then re-check it. | ||

+1 on that, and if it still is wonkey, GET HELP! If the thing ran ok till you started mucking with it then you need to have someone un-muck it up who knows Spyware, they're proper values and can diagnose the issues. |
