Very cool app, no nonsense, no ads, just served purpose, easy to know all DTCs even TCM and can read live stream data of transmission shaft speed too

Very good and quick to connect unlike others. But need to upgrade more functions for Asian made vehicles. Nissan, Toyota , Mazda Isuzu and Ford Just to name a few.

KONNWEI has three apps for their BT scan tool! KDIG and MAXOBD2 require the BT dongle to be plugged into the vehicle's OBD2 port. Both apps require permissions to be set manually within the app settings menu to work. KDIG app instructions say user should not connect BT dongle to phone BT and should use function to connect BT within the app!

Does NOT DO EPB RESET ON NISSAN. Developer does not reply. At almost every menu it prompts for an update, some can take over an hour to load. Many selections give an error. Useless. Returning adapter for refund

Most functions do not work with KDIG scanner.

Glad I didn't buy the obd2 connector! The KDIG OBD2 on AliExpress had pictures of it having holden protocols, it doesn't even have holden in it.

Had a lot of hope for KDIG, but it can read neither of my cars. It only shows basic info like every cheap obd does. Unfortunately KDIG OBD is useless, same as the app.

I bought this device and still can't connect via Bluetooth and the app.I called the konnwei dealer and can't resolve the issue. For me its jst useless and I don't encourage anyone to buy it. Konnwei 903 wireless 5 Bluetooth
