tune ECU shows TPS of 78 at full throttle.

I recently aquired the cable and hooked up to TuneECU. Going thru the paces and notice the TPS gauge shows 0 at no throttle and 78 and full open.

I reset the TPS and let it idle for a while several times. Still at 78 wide open.

Is that normal.

Bike runs okay, mild surging 2500-3500 constant, which from what I gather is quite normal for these.

Any help?

Yep that's normal

If you are confident to change some settings in the 'F' map, the surging can be cured.
