Range TechnologyRA005B GM Start/Stop-Blue

I use it all the time

The idiots who came up with auto shut off are completely clueless and need slapped. It’s hard on your engine and engines use more fuel to start than to just idle for short periods of time. Seems like the newer “technology” is garbage and we need to go back to 2006 with the lbz duramax and 6.0 vortec with ecm’s that actually work and engines that actually run good. Except for the scrapyard junk ford was producing and is still producing. This product did a great job of fixing the blooper of auto shut off.

Easy install

Plugged it into the OBD2 port of my 2020 Traverse and the annoying Auto Stop was gone. Has not affected operation of anything else as far as I can tell. Remote start functions normally as does everything else. It is an LS, so it doesn't have any fancy stuff. It will drain your battery if it is plugged in and the car is not driven for a couple weeks. Pull it out if you will not be driving the car or use the remote start to charge up the battery. Auto Stop gave me the willies when trying to pull into traffic quickly. They say the starter is designed for it, but you can't cycle something 20 time the normal usage and not wear it out faster.

Whe buying from "Range Technology" this unit comes with the LATEST updates. The unit I recieved from Amazon it would NOT work at all on my Late model 2019 Chev Silverado. I would have given 0 stars but that was not an option!!

2019 Silverado 5.3 LTSuper excited to utilize this module, it did disable DFM. However, it did not disable Auto Start/Stop. I still have to hit the button to turn it off whenever I start my truck. Not sure if my module is defective or if Range's software cannot override a physical push button. Met half of my expectations.

Does NOT allow auto fuel management (AFM) to switch to V4 mode, as it is suppose to.Used to switch to V4 a lot during city driving, SAVING FUEL!V4 mode on the highway constantly switching to V8.1-2 mpg loss with this installed but has positive potential to avoid very expensive valve train repairs from poorly designed system.Additionally, has reduced my oil consumption associated with this AFM POORLY DESIGNED SYSTEM.Such a shame GM couldn’t make this fuel saving system work properly without ruining your engine.

Does exactly what it is supposed to. It seems like the shift points changed a bit with the 6 speed transmission also. My MPG increased slightly but I do a lot of highway and have a CAI and exhaust.

Works great auto stop start gone, and remote start features work properly. The only thing I noticed is that the my Chevy app will not update for diagnostic report it says something is plugged into obd2 port witch it is, other than that it's great.
