Plug for the Biscan GM torque pro plugin
I know people have posted about this before, I just wanted to post my short review of the BiScan GM plugin for Torque pro. The app costs $29.95 on Google Play, in addition to the $5 for Torque Pro. I'm using it with an Obdscan MX bluetooth adapter and a Google Pixel 2 phone. I was looking for something that could read back the injector balance, all of the DEF and emmissions specific codes, and perform some of the basic reset functions like force regen and SCR reset and command EGR value. While it doesn't have all of the features of something like a Tech2 (you can't command individual injectors to open or access the Allison transmission controller), it costs a fraction of the price and still gives you great information about things like regen count, injector balance, soot mass, turbo vane position, and injection/fuel pressure status. It also adds those gauges to Torque Pro so you can log the sensors over a trip and post it to the web for later analysis.
I think it's a great tool for the price if you have an LML and want to know the health of your duramax.
