Low gps signal.

No matter if im in the middle of town or at the track the app always says low gps signal. Full service and LTE internet gps is turned on for very accurate. Just doesn’t want to get good signal no matter what. Find a friend can pin point my exactly location but this can’t.

Old one was better

The older version was more accurate. This version has trouble acquiring GPS signal and I know my car is a mid 15sec to high 15sec 1/4mile car but app kept showing me 17sec 1/4mile at 89mph. I believe there’s a delay time when the app is trying to acquire the GPS signal and it throws off the 1/4mile time, since the GPS signal was having difficulty acquiring it. Mph speed seems ok though! Think might just bust out the old fashion G-Tech meter that’s more accurate!

Horrible GPS

It’s an hour drive to the track and I have to do my testing on back roads. 60” and 1/8 mile. It doesn’t help when I get crappy GPS although my signal on my phone shows 100% the app can’t seem to get it straight. Two seconds into my run and GPS drops out. Seems like a common complaint on here. 95 mustang GT built engine, supercharged around 500hp. # No crowds were injured in any of my test hits.
