I messed with the suction cup on the windshield and could not find a place I liked the location and the damn thing would come unstuck at random times.

I ended up putting it between the center vents using four small round velcro buttons mounted to the outside rim of the suction cup (and the dash of course).

Working good so far.

 

are those things accurate? I hate the idea of driving ~80 miles each away to Moroso in West Palm only to get in one run an hour while all the damn hondas clog up the track with their 16.5 dial-ins...

All the experiences I've read say they are providing you have a straight/level piece of pavement (and your weight is input accurately for the hp/tq calculations if you care about that part).

I purchased it more to work on my 0-60 than anything else. The few runs I've done, the G-Tech figures seemed reasonable.
