Works great, with a noticeable difference in performance. Great adjustability and continually updated firmware. Installation was pretty straightforward.

After install my app will not find the device. Only works on old OTB cord and old JB4 app. Not pro

A JB4PRO BT adapter is required to use the new JB4PRO free app. This app is not compatible with JB4 Mobile adapters.

So far so good. Had a few hiccups but was remedied by the developers within a day or so with a new update with exactly what I needed.

What’s new

1) Changed firmware download to internal BMS database
2) Changed Trims/Trims2/Timing to Fuel Trims/Fuel Trims2/Ign1. Adjust gauge templates as needed.
3) Adjusted Fuel Trims scaling to reflect -34 to +34. CSV will still store previous 0-50 format for legacy compatibility.
