I pulled the trigger on one of these yesterday, (Scangauge II)
and all I can say is these should be standard equipment! For ALL cars!

Mine is new so it has the newer firmware.
So far I've adjusted the speed % to within 1mph to the GPS.
I hope to fine tune it more.

Has anyone programed the Transmission temp gauge AND made it work?
I've just added the monster size tranny cooler so I want to monitor temps.
I do tow with mine.

Anyone have some easy mounting locations?
Looks like I'm going to make a bracket mount near the ashtray opening.
I'm not a fan of Velcro tape...
