JB4 Mobile

The new update brings the app to the 21’st century. It’s great and let’s you choose exactly what parameters you want to see and match the colors to your car’s theme. Only thing we need now is Carplay integration! There is an app developer who created exactly that. It’s an app called “OnTrack”. Let’s get his technology unto JB4!

It’s needed the app for my tuner. For the most part it’s great on the fly. I’m able to check my logs, switch my map, change my tune. Love it. Unfortunately I’m missing some parts of monitoring. I’m sure it’s due to availability and car. But I’m unable to get my Trans temp, oil temp, and some other. I also do wish there are more different styling gauges. 5.26.25 - So the update on the app is nice. FYI…the graphs and such can be found in the files folder if you have an iPhone.

Great app for a great product but it really needs to be integrated with Apple Carplay. I’m hoping for the upgrade soon. Then I will switch my rating to 5 stars.

Purchased the app a few years back when I worked for a BMW performance shop and hadn’t used it in quite some time. Downloaded today so I could interface with my wife’s car and I have to pay for an app I’ve already purchased once?! The whole reason I paid for it the first time was so I could use it when I wanted. Honestly you’d think if you bought a $500+ programmer and paid the extra for Bluetooth connectivity bringing the total over $700 the app would come with it.

Please develop car play support so we can monitor gauges on our car screens!
