I bought a copy of VDSTS from a former forum member several years ago. Today, the 1200 Sport decided to go to high idle speed, so when I got back from lunch I decided to balance the TBs and (of course) reset the TPS. I used directions from John Z on GuzziTech, which provides simple to follow directions.
But it seemed to take several tries to do the initial TPS reset (per John's directions) and do the final reset after performing the high speed balance. The first couple of times, I continued to get a reading of 5.2 vs 4.6 or thereabouts, so I'd perform the TPS reset again.
I suppose if I used the VDSTS package weekly, I'd understand it better. But coming back to it after a year or so, it didn't seem intuitive.
I know ..... the answer is GuzziDiag, but I already own this package and have it installed on a garage computer, so I guess I'll live with it.
I've always thought that Guzzi could have included the TPS reset routine in their ECU firmware, vs requiring use of an external software package.
