Ultragauge data

[HollywoodTurbo]

anyone else notice a difference in the RPMs between the ultra gauge and the cars tachometer? I start to notice a significant difference for anything above 1500. The car says 1500 but my ultra gauge says 17-1800. While cruising at 65mph, my car says 17-1800, the ultra gauge says 20-2100.

We have long known the UG updates it self every several duty cycles not real time.

The tach is slow in the car. The ulttagauge could be correct if accelorating. If maintaining speed and you see a difference. That could be odd

Yeah, Preloader has a video somewhere showing his aftermarket tach next to the built-in tach and the aftermarket one is WAY more responsive.

^ Yeah, but I believe that's also with modifications like a lighter flywheel.

Test the UG vs the stock tach with the cruise control on while on a flat road. Let it stabilize and see if there really is much difference or just the 1Hz (seemingly) rate of the UG.
