Anyone speak TPS?

<< < (2/2)

Haakon:
A even more stupid question:
Is there any real reason to calibrate TPS and Iddle actuator?
I have the impression the ECU is self learning and self adapting?
(meaning, that both will read and learn new values real fast, while riding?)
If parts have been exchanged or by other reasons give other values than earlier, the ECU will self adapt?
(For older bikes the easy way to reset the TPS was to turn on the ignition and then turn the throttle slowly from max to min 3 times- adaption done)
Maybe just heresay and superstious....?
Same with the iddle actuator- a working O2 sensor (Lambda sensor)will help the ECU establish and learn the actuator settings. A bit more difficult than TPS but basically thr same thing.

might be a stupid question but as i have learned the hard way the only stupid question is that one that was not asked...
have u re-calibrated  the tps and re calibrated idle actuators

Yeah. I do the idle acuator calibration every service and I did it just a few days ago.

I don't know about the acuators but the TPS seems to learn pretty quick.

I don't know if I will ever figure this out.  I did 200 miles today and it ran perfect.  It is the intermittent nature of the problem that drives me crazy.  Runs /idles perfect for weeks then won't idle at all then magically returns to a perfect tune.  Great fun.
