0-30, 0-60, 0-62, 0-100, 0-120, 5-60, 30-50, 50-70.

You'll also capture:

1/8 Mile Time and Speed, and 1/4 Mile Time and Speed.

The best part is this information is *automatically* captured and saved while you drive. No fumbling around with cables and cords, and no starting and stopping the app. Just drive and forget!

Plug the adapter into your cars ODB2 port and connect to it in your Wi-Fi settings. Launch Quarter Mile Pro and you're set!

Couldn’t get it to work at all maybe I miss read the instructions


Chevy Nova

I wanted a way to check on the progress of the mods done to my car. I saw your app and thought it was what I needed.

I didn’t read the comments, mainly the part about the ELM327 adapter and plugging into the ODB2 port. My car is a 1962 and “doesn’t have no stinking ports”.

Is there any way to make this app work with my older model car?

Thanks, CC
