I have always used OBDLink MX+ for all my cars. They recently came out with their CARBYTE product to defeat the AFM stuff. I have put a few hundred miles on the car using their device and it works perfect. Most importantly, it is SEMA Compliant. More information is available at carbyte.com and their SEMA Certificate is here: https://www.semagarage.com/CertEmiss...2023.09.19.pdf

Thanks for the recommendation on another AFM Eliminator. I've been using the Range Device for years and never had a problem with it - so no need to swap at this point.
I was one of the Beta testers and I have been using one most of 2024 both in my 2022 Silverado (no AFM - Computer Shortage) for Engine Auto Stop defeat and on my C7 Grand Sport for AFM defeat.
I also have a Range Device but it gives me problems at Inspection time. The car reports NOT READY for State Inspection. I have to remove the device and go through a painful process described by GM to make the car ready for inspection. I don't see that problem with the Carbyte. I now have 2 released products and they work better than my beta test unit and there is a phone App to connect to them.
These are from the same company that manufactures scan tools (scantool.net) that I have been using for years. I currently use the OBDLink MX+ version. Works great with an iPhone. That is the tool that I use to see if the car is ready for inspection before I go to the dealer.

Reason: Fix Typo
Yes, many of the sensors have not completed calibration. Three vehicle cold starts were not enough for me so I had to resort to the GM Process two years running.
It is not clear to me why the Range device needs to do this. I can remove the Carbyte and use the scan tool to check the sensors and they are not disturbed.

what happens when this device/range/etc...... are removed for emissions tests, does the vehicle need to re-learn anything??
Not relearn, I don't think. There are emissions readiness tests that need to be done to have the vehicle ready for testing. If it isn't ready for testing, it's an automatic fail. So you change the battery and then drive to the emissions stations down the block, doesn't matter. You fail. https://www.obdautodoctor.com/tutori...ors-explained/

change the battery?? to reset cel??
not quite as simple as going down the street for another test!! all test facilities are run by the county, tied to azdmv!!
pay the fee, pass or fail....if passed can renew registration!!

You'd be surprised how many people do that to try pass emissions. Friend of mine at one of the stations has often scanned it with his own dongle and found that they have somehow cleared the code 3 miles ago, 0 warm up cycles, etc. etc.
Don't know. We have a couple of Lube shops that do emissions on weekends and some mechanics. All have to be state certified and have state certified equipment. Doesn't cost you a penny to plug it in. They try to talk you into using them for repairs if the CEL comes on.

Milwaukee (don't ask. I don't remember) just installed a couple of stations. Plug in and test and drive off. So here's the deal. You CANNOT register your car until you pass it. It is hooked up to DOT. At the end of your year, you get a renewal notice. Try to renew and it won't work and tells you to go test. Right after you pull out of the station, you can hit the "submit" button and it will know you have passed, assuming you passed.
Where the shops get you is that most people wait till the last minute or last days. This is where you are more likely to sign up with them to fix your car since they are in front if you. Here is your joke for the day. The shop has to spare someone, do the paperwork to get the equipment and pass the class and get to deal with the customer who is pissed that his car didn't pass. $3. That is what they get. Understand that in winter, when they roll up the door to let you in plus use the tech's time, I'm not even sure that the $3 pays for the heat loss.
