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

if I can please get in touch with the developer. it was working before I purchased and now I'm having difficulties. mc vlinker. 3.0. Please help or refund. literally just want to enable one feature on 21 blazer. After blow. pairs, reads vin, but doesn't say connected to vehicle.

Must have for any GM owner looking to work in their own vehicle. Dev is super active at adding and improving features that makes any routine maintenance tasks much easier without having to have a dealership involved. Make sure you get a proper OBDLink as well, their website makes it real simple to pick out the correct one.
