TPS voltage

[duckspeed]

Is it possible to set the TPS voltage using a meter on a 1200 as I have done before on 1150's
The reason I want to check is that at just a whiff of throttle feels like the bike will not run smoothly as if the ECU thinks the throttle is already shut.
I have spent some time setting up the throttle bodies using a carb balancer at 2500 rpm, and general performance is really smooth and progressive.

no

no

Thanks for the extensive reply Jonno, do you think I may be on the right lines?
Can I bring it in for you to have a shufty at ? Will Hobnobs help at all?

To put a bit of flesh on that for you ...
The R1200GS does not need the TPS positioning correctly; it learns where the closed and fully open positions are and works out the bits in between.

To train the ECU, disconnect the battery for 30 seconds, and reconnect - this makes the ECU forget the current settings.

Make sure the engine run switch is in the run positiionn and turn ignition on. Open and close the throttle fully fully slowly 3 times, then turn the ignition off, back on again and start the engine.

The ECU now knows and remembers whatever voltage it saw as the minimum to be the fully closed position, and the maximum voltage will be full throttle. For voltages in between (i.e. partial throttle) it can calculate how open the throttle is.

The short answer to your original question remains though: "No"

I have read about this many times on this forum but this has to be the most thorough explanation I have seen of this simple process. Good one Mag...

Thanks for the reply Magwych, I will give that a try tomorrow, bloody clever those Germans. I am aware that I may be trying to get rid of something the manufacturers often refer to as "characteristic Sir"
