You measure the TPS with a couple of pins and a good DVOM. The input voltage and output voltages are listed on this page. Injectors clogged? Again, where is he getting this from? If the tps were really at 90% the engine would flood and that would be the end of that. I suspect he doesn't really know what he's talking about. This is a mapped/open loop system. There is no feedback, just a cell map for each situation.

- May 09, 2022, 09:41:17 AMi recently completed the following upgrades (if they would work right) on my 99 VN1500j:
+6" throttle cables
Barons Big Air KIt
Hardkrome 2-1 Sideburner Exhaust.
I took the bike in to get custom mapped and dyno tuned and the mechanic said that he couldnt do it because the Throttle Position Sensor is telling the ECU that it is at 90%. I followed the manuals instructions on testing the resistance across the 2 pins on the ecu (resistance or voltage, i dont recall...) and it is supposed to be within a range of 4.(something)-5.(something) and it read 6.4. Could i have inadvertently bumped something whilst changing cables? is there a way to adjust the tps? (i found the gadget adjustment technique, however not for this exact problem. will that work to zero the tps back out?)
the mechanic also said that the injectors may be clogged. now i put 600mi on the bike before the new equipment was installed... could the tank removal have dislodged some material that clogged the injectors? To me it sounds like the mechanic just doesnt want the work... as he says hes a month out to work on it. I wanna ride this thing so bad but it wont run right as is. PLEASE HELP!
