Did a throttle body synch on the Stelvio this morning. Up to now, I've always done it the "official" way, ie, close the bleed screw(s), high speed synch with the screw, low speed synch with the bleed screw, tps reset. That's fine if you have understanding neighbors.
This time I did it the other way round.
1) close the bleed screw(s) (they were both closed anyway).
2) synch the idle with the high speed screw
3) tps reset.
Checked the high speed synch and it was spot on.
Much quicker, less engine stress and happy neighbours.
By the way, I used a CarbMate that I bought 2 years ago for the first time. Up to now I always used a set of mechanical vacuum gauges that I've had for over 30 years. They're nice, but the CarbMate is less fuss and quicker.
