Accurate within 0.1-0.2 seconds I road &drag race my modified 370Z race car. Its equipped with a Stillen Supercharger & plenty of other goodies. At our local drag strip my Z ran 10.09 at 132mph.I have another 370Z as my daily driver. The only mods it has is Nismo R-Tune, long tube style CAI's, Stillen 3 into 1 headers, CNT hi-flo cats, an Ark Grip cat-back exhaust,& last I had the ECU UpRev tuned. My daily driver runs low 12s.Ive compared track times to the app times,very close,within .1-.2 seconds.A nice device is helpful.
Good app but needs work. I also get "must be at s standstill" even when sitting on a pile of paving slabs. Did get 1 measured time but Measured the same time for 0-60 as 330' but had me at 67mph at the 330' ! (same run)
Stupid AF!! This thing can't even keep up wit my modded grand am gt. I was at 60mph and it said I was doing 25mph. I don't see how it can keep up with Zondas, Veyrons, or even GTis that I've seen in other comments. People should get a friend with a stop watch to time their 0-60s
No communication? Done every possible combination, phone attached just below winshield, this is SO far off, great sat connection and still get horrible lag. Sent email, no response in return to simple program questions. I'll use others available, shame there aren't more that keep true "multiple real track" results.
Slow response, but it will provide a picture of performance. To be able to start the test, the vehicle must be at a complete stop. But the problem is that the vehicle's complete stop position could also be misread by the app and/or GPS satellites. There is a compensation feature within the app, but I don't know if it really improves on anything.
Works fine This app only works as good as the GPS on your device. I've gone through a lot of custom roms and have done a lot of testing with GPS and I know that getting good GPS reception is hit and miss especially with stock roms (I guarantee 90% of the commenters are running stock). This app works great, but most commenters don't know what they're doing
