Updates my old car.

I drive a 1999 Pontiac Bonneville, and can now watch my fuel economy, watch what my O2 sensors are doing, MAF, etc., record all my trip data, create my own dash, troubleshooting codes, and many more. I just recently replaced all upper gaskets on that ole 3800 with 240,000 miles on it, lower intake gaskets, upper plenum and gaskets, valve cover gaskets, new water pump, new radiator, plugs, wires, and was worry free with the OBDLINK connected on startup. Absolutely no errors, and watching the engine basically retune itself was really cool. Highly recommend this device if your a nerd like me and love watching and learning the awesome technology in our vehicles today. It’s truly amazing.

OBD WIFI just works

I wanted to reset the codes and see other OBD info and this device works great. I leave it plugged in and never have issues as it goes to sleep mode automatically. With the WIFI interface I also still have all the Bluetooth functionality of my hands free for phone and streaming music from my iphone over bluetooth. Great addition to my gadget collection and since it saves my settings only have to use one for all my cars. The guage function is very cool. Will buy the extended software to get the additional brand specific codes as well. Thank you for a great purchase!

Works Great, Enhanced Diagnostics are awesome

I have been a Torque Pro user for years and do really love it, but my work uses iPhones and there was really no equivalent for a long time. I just bought an OBDLink MX+ and decided to try this app again after a few years and it’s great. Very similar setup to Torque, but what really differentiates it is the Enhanced PIDs. I downloaded the 2014 Ford add-on for my F150 Ecoboost and the list of Ford specific PIDs just in the PCM section is huge. It can see all sorts of other modules as well.

My only big complaint is that there are no add-ons for Chrysler/Jeep which I would love to have for my diesel Liberty.

Also, if you made this Apple CarPlay/Android Auto compatible it would be EPIC!
