FOXWELL NT710 Fit for GM Chevrolet Buick GMC Cadillac Car Scanner Diagnostic Tool, Bi-Directional Scan Tool with Full System Diagnosis All Resets Vehicle Code Reader, Crank Sensor Relearn OBD2 Scanner

Work good ,nice data screens, works for C8 trans flush procedure.

If you turn wrenches every other weekend and are always helping friends work on stuff this is for you, if you’re full time shop tech I’m sure you could get by but this only comes with gm programmed first you can buy each vehicle you need for 80$ which isn’t hateful

The biggest thing I did NOT like was that I had to go online and register this scan tool. Once I got past that, everything was pretty much wonderful, lol. Touch screen. Lifetime free updates. GM only. This tool accessed I think about every option I could find for my 2003 2500HD Duramax. You can record and save live data. I really like how I could check and record my injector balance rates before and after I installed my FASS lift pump. I think my lift pump combined with fuel additive really cleaned up my injectors. My worst injector was -3.70, and after about 200 miles +/-, I checked the balance rates (can show 4 on screen at once), and my worst balance rate was now -1.70. So, I was very happy to know that I didn't need to spend about $2500 plus labor replacing injectors (for now). I paid about $300 for this scanner, and it was worth every penny. Do so at your own risk, but I will recommend you get a usb cigarette lighter plug and keep the scan tool plugged in while your vehicle is RUNNING. It does pull a lot of juice, and if you use it for a long time, you will need to recharge almost every day. I sat there in my truck with the usb plugged in charging and the OBD2 plugged in for over an hour just looking at all the stats for powertrain, fuel system, transmission, etc, and the truck charged the tool up to 100% while in use. Again, this is for GM vehicles only. 5 stars for now

Diagnostics worked very well on the L18 in my Workhorse W24. Could 2-way communicate with the ECM and TCM. The Datalogging feature was useless, cannot scroll though the time series, cannot export the data in a functional way as it is encrypted. Useless for troubleshooting. I returned this product for that reason.

This is a decent tool to add to your toolbox for diagnostics. It can be a little confusing to navigate through. Maybe with prolong usage you could find all the features it has to offer. The company claims you can operate individual modules in your vehicle but I have yet to figure out how to do that. They come pre programmed for one make of cars, if you want to diagnose other makes then you will need to buy the programming and download it on the scanner. Each one is around 80 dollars. Getting them to download on the scanner was a little confusing as well. If you are just a home mechanic working on your own vehicle this may not be the scanner for you. If you are a mobile mechanic or a shop mechanic and have extra money to download all the makes of vehicles and have time to figure out all the functions this scanner has then this may benefit you.
