OBDLinkMX+ OBD2 Bluetooth Scanner for iPhone, Android, and Windows

I bought this to debug the TPMS lights on my 2019 Promaster using the AlfaOBD software on a latptop PC. This did require the yellow low speed adapter cable to communicate with TPMS on Promaster. I also used the MX+ to clear an evap code on my Honda Odyssey using OBDLink Android app. Previously, I've had $15ish ELM327 bluetooth adapters with different Android apps such as Torque Pro. 1 from 12 years ago. 1 from 4 years ago. The ELM327 stuff worked some, but they were always difficult to use, flaky connection, and would not access the modules I needed to access. The MX+ connected right away to both my laptop and my tablet. OBDLink company has email support that responded. The MX+ plus has firmware can be updated and indicator lights so you know when it's doing somethng. ODBLink's Android app worked well for debugging, but I have a Scanguage 3, so I did not use it for gauges while driving. I was skeptical about the $140 price for a bluetooth anything. If you are considering buying a dedicated mid-range scantool, this could be a good option with the right software for your make of car. Comes in a nice zipper pouch, but glossy box with magnetic closure is way over packaged.

10/10. Love that I can change DRL lights from high beam to turn signal lights. Looks awesome. Plus I can lower the voltage. Also awesome. The App itself (AlfaObd) costed me $52. The one I chose for changing DRL lights. Connects really fast. Good quality. Has its nice little case where the obd2 kept in. Reads even the codes for BCM. You can change literally so many things. But I recommend first to upload a backup file to Google drive if you want to do something with it. Eazy to mess your car up. Also, when you change stuff, you don't have to wait at all. You can change for example the voltage of high beam live. You don't have to turn it off or do anything. If something is weird. Just turn it off and start the car again. I was doing changes right when the car engine was running. Only one issue so far when driver side led didn't light up at all when I was changing its voltage. I thought I killed it but no, it was just an internal error so restarted the car and the led worked again. Watch some videos before using the App. But if you come across the guy who says you have to wait for 5 minutes.. no you don't. Like I said I was changing stuff live, so I could monitor love what I am doing. Originally I bought it bc I have a van that has high beam daylight running lights. It was fine with halogen bulbs. But once I swapped to LED it was just blasting them like I had them on, blinding other drivers in the front of me. And when I turn them on it didn't seem to make any difference because it was almost full power applied. Sometimes I got some drivers blink at me lol. I was thinking to change it physically to rewire stuff. But decided to go easier way. Get it now !! It's a game changer.

I use this on my 2020 Tundra, I added a transmission cooler and wanted to make sure my temps are low. The unit connects quickly and performs flawlessly offering very detailed sensor readouts that I needed .Transmission fluidTemp, Trannsmission pan temp, oil temp, coolant temp and literally hundreds to choose from. You design the dashboard and put the gauges in the spot you want on your phone or stereo if it has that capability. On the Tundras 2019-2021 Toyota didn’t continue adding transmission coolers, so if you have a transmission warning light appear on your stock dash, the trans temp is already at 302 degrees. Heat breaks down fluids and will cause premature clutch plate wear. Smart to add a transmission cooler if you plan on towing or driving in mountainous terrain, may not have problems if you don’t, but if you do it’s now a 7,000 dollar problem, this OBD reader monitors in real time and will save you money and alert you to issues before it’s too late.

Bought this to diagnose Airbag dash light issues on a Tacoma. Customer service was contacted and quickly respite help to get the device looking at the SRS system for the truck. It was able to read and pinpoint the sensor correctly for a home diagnosis and easy repair. Very nice features for monitoring car PIDS. I would highly recommend.
