If you have a WJ 2.7 you NEED this app. Only runs on android which is a bit of a pain being an Apple user, but you can get cheap android devices/phones to run it. After five years of pulling my hair out at not being able to diagnose issues, beyond doing the "old three key dash routine" (which tells you very little). And very few workshops (in Australia at least) have software to diagnose 2.7's. Get it! You won't regret it. Faults, live data across every key function you are likely to need. And great support.

Hello! I have alredy purchased this app, it's a really great thing. Just have some questions - is it possible with the app to learn new keys (immo) and remote? And I can't found the option "brake bleeding". Where us it in menu? Maybe I have not the original ELM.

Very good app, works excellent. Do make sure to buy a real ELM device, it saves a lot of headache (and money, on the long run).

great app perfect for the 2.7 crd gives me access to all the information I needed on the gearbox and being able to reset the codes after installing my new conductor plate as other apps do not connect to the jeep

The only real alternative to a DRB III for the Jeep GC 2.7 CRD. Developer support is first class. Thank you for continued improvements. App has paid for itself many times already.

It's an amazing tool to have, the actuator tests update is another big leap forward
