Just wanna see if anyone has any insight. Have a 16 stock axys 800 that started not pulling rpms a few weeks ago. Will rev very good to 7500 and just stay there. Its like its rev limited to 7500. No check engine lights, no codes. Clutching is all new and in very good shape. Here are the other things I've tried.
Pulled the EV and cleaned
EV cable good shape
EV recalibrated at dealer
Replaced all 3 relays. They were in very bad shape.
Adjusted TPS by myself and the dealer
Tried the EV actuator out of a good running sled
Tried exhaust temp probe out of good running sled.
Tried EV PWM converter out of good running sled.
Tried ECU out of good running sled.
Ground wires on bumper bolt cleaned and good connection.
Nothing fixes or changes the 7500 rev limit. While I was trying the EV actuator out of the other sled, i noticed sled revs great with the EV actuator wiring unplugged and EV held wide open. Weird! So i can plug everything back in, all 100% stock and rev on track stand and rev limited to 7500rpm. Unplug wiring to EV actuator and hold EV open and it revs as high as you wanna go, 8400+ easily.
The only thing I can think of is a main harness problem/short/broken wire somewhere. Anyone else have any ideas?
