Ratings and reviews

Replaced my DEF tank heater in my 2015 Duramax but struggled to clear the "service DEF system" warning. Needed to initiate all 3 DEF heaters before the truck would kill the impending speed restriction. My current scan tool wasn't able to command each heater on, but this tool certainly did! I have is a ELM327 BT adapter, but like others have said, its too slow to stay connected reliably but it stayed on long enough to run all 3 commands. Ordering a MX+ today. Best $20 I have spent in a while. TY

This needs a trial for 30 bucks a year. It didn't do more than what I could accomplish with torque outside of accurate tpms sensors. The gear is incorrect, the gas milage is in l/h, you can't use torque widgets with this. Overall, definitely not worth 30/year. I'm very much willing to pay 30/year for torque looks and all gm pids. This isn't that.

I emailed the developer a couple questions regarding my intent to use this app to force my diesel Chevy Colorado to regenerate the DPF. I have very basic knowledge of this stuff and Justin patiently and thoroughly answered my questions even though I emailed him on a Sunday. Bottom line is, I was able to force a regen on my truck and monitor the progress easily. I have had to pay for this to be done by a mechanic three times this year. This app will definitely save me money. Thanks!
