Phenomenal for 16 LML Duramax
I bought the lml rpo pack and have been using gretio with the obdlink mx+ to work on my 2016 Chevrolet Duramax LML and it’s been great. From the egr cooler bypass valve to the reductsnt tank heaters to the NOX2 sensor, this has proven to be invaluable and helped save me thousands of dollars doing things myself. Highly recommended!

Connection problems with obdlink mx+
I bought the lml rpo pack and have been using gretio with the obdlink mx+ to monitor my 2016 lml duramax while driving. There are connection problems. I connect the obdlink mx+ to my iphone 11 pro running iOS 18.5, but when i then try to connect gretio, it doesn’t connect and the obdlink also disconnects and then has problems reconnecting. Ultimately , after factory resetting the obdlink and reconnecting from scratch, gretio will connect. But not always. Sometimes gretio still won’t connect and still disconnects the obdlink. Very frustrating. Sometimes it works and sometimes not. Something is not right.

Extremely powerful for the cost
Worth every penny considering a dedicated scan tool with the same capabilities would cost you over a thousand bucks. I downloaded this app just for the service bay test function to clear the dreaded “poor DEF quality” countdown to limp mode on my diesel Colorado. Highly recommend!
Incredibly Capable
Though not super slick and sometimes crashes, this app is an absolute powerhouse for dealing with complex, intermittent sensor issues in modern diesels. Without question, I would not have been able to resolve my issue without it. Be sure to track down their troubleshooting guide if you are chasing diesel emissions issues. The guide brings context to the data and maps a path to resolution.

2017 GMC Canyon with 19 miles before limp
Found a forum where the author said he had a truck like ours with similar issues, and that he had an app for that! Bought the OBD link mentioned for $138 on Amazon and paid the $20 for the app. We also replaced the Nox sensor 1 to start fresh(er). Hooked the OBDlink up to Bluetooth, used the Gretio app to run the DPF Service Regen, (so cool to watch the soot percentage come down)then the DPF Reset, then the Reductant System Malfunction Warning Service Bay Test and all is right in the world again.
