[skidlids]

I've had a look through all my nfo and had a search of the web but have failed to find the set up values for the TPS for either a 998R or 998

Unlike many of the later models that use the 5.9 ECU the 998 still uses the adjustable non linear TPS so needs setting manually

The values I need are the readings in millivolts (mV) for both the fully closed butterfly position and then the idle pos'n

Thanks in advance
Kev

Although the 998R is not mentioned in this article by Brad Black on setting up the non-linear TPS, I'd be pretty sure that it will be the same as the ST4s and S4R which use the same TPS and 5.9 ECU. The TPS is still set at 150mV with the throttle fully closed and the idle stop backed off but you will have to "backprobe" the pins at the TPS to get a connection between the black/violet and orange wires.

I have consulted Brads site quite a few times in the past and even had a look yesterday for info on the 998s, I hadn't considered the information regarding the S4R or ST4S. as you say there TPS settings could be the same as not many bikes use the 5.9 ECU and adjustable Non LinearTPS.
I while back I made myself a short patch lead that plugs in between the TPS and its connecting lead that allows me to easily read the voltage.

Job for tomorrow evening I feel as its the local bike night this evening so i'll be off over to that

Remember to note the readings first before you adjust anything. If it turns out wrong you can always set it back to where they were before.

Already done the idle pos'n reading it was in my post on Saturday under the DD section, titled along the lines of I'm ready for Cadwell.
Reading I got was 405mV which should equate to 2.4 degrees

Had a bit of time to play with the 998R again today.
So started off by taking a TPS reading for the current idle/tickover pos'n after adjusting it the other day. The multimeter read 424mV.
I then backed off the throotle stop screw on the front injector body that houes the TPS, meter reading down to 123mv, I then backed out the throttle stop on the rear throttle body and the reading dropped to 96mV. Finally I slackened off the throtle cable and we arrived at a TPS value of 57mV for fully closed.

Its hard to believe this bike has done less than 300 miles since a £4.5K engine refresh and set up of the FIM ECU we I have now removed as the bike just died when the throttle was wound open quickly, as you would when over taking.

So I have now set the TPS to 149mV in the fully closed position and then wound in the front throttle stop until I got a reading of 394mV.

Just about to take for a test ride and then when I have some more time I'll balance the throttles and set the CO2
