BiScan for GM

Surreal Development LLC

About this app

BiScan is a plugin for the Torque Pro app, and thus having the Torque Pro app is a requirement for using this application. BiScan adds PIDs (Parameter IDs) to Torque Pro which can be used just like any other PID. It also has the ability to perform diagnostics, such as a Service Regeneration, or adjusting the idle speed.


--- Supported Vehicles for PIDs ---

2010-2016 LML Duramax Silverado/Sierra

--- Supported Vehicles for Vehicle Controls ---

--- Disclaimer ---

This app requires advanced functionality which may not be present in all OBD2 adapters. As such, some adapters which work flawlessly with Torque Pro may not work with this application.

This app is targeted to only work with vehicles in the supported lists.

Due to the high volume of clone Elm327s out there. Please use another app to verify your adapter, such as "ELM327 Identifier" before purchasing. Green up to 1.3 is preferred.

Warning: BiScan is maintenance only thus no features will be added. We highly recommend using the “Gretio” app instead. BiScan will still remain here for legacy users.

Ratings and reviews

Need help 2014 Duramax 8 vin# everytime I try to connect it says do not have permissions bitscan off? For anyone else that has this problem the team over that got back to me in a timely manner and just open your torque app go to settings and enable the bitscan working great thanks,

Does as described on the tin, great work. Used on my 2016 gmc canyon diesel. Have had to take to dealer twice to get regens done, at 180 bucks each time. The 37 for the app (on top of torque pro and obd 2 reader) well worth it.

Did exactly what I needed, thank you very much. Doing service regens helped me clear my dpf and pin point my emission problems with the built in pids and scanner which is set up nicely.
