User reviews

Tracking

Give your location or else app won’t work :/

Needs improvement

This app needs improvement, things like the gauges in screen rotation, data logging, and extra gauges. Gauges in the home menu go from being a 8k rpm layout to a 16k limit when the screen is rotated to landscape and back to portrait. Data logging is real time only there’s no saving the data is displays, it also stops recording when throttle is off(deceleration) and continues when throttle is applied but has a tendency to not record anything even when you apply throttle or just idle. Extra gauges can be things like individual injector duty cycle, amount of extra fuel it applies when on E, and the ability to maybe use a external obd2 dongle to gather more data and record in app for data logging.

temps are off

I’ve been using the app for a while to track ethanol and temps. It’s been off on the temps. Showing that my car only ever reaches 50degrees celsius (122 degrees Fahrenheit). Just a bit worried some of the other gages being off as well.
