I'm not sure how long the Dinantronics X has been out but I can't find any good comparisons between it and the JB4. It looks like it's intended to compete directly based on features and price.

Has anyone tried it? Tried both? I'm interested in any general comparison. Specifically though I'm targetting a stage 2 tune on a B48 (330i xDrive).

Dinantronics advantages:
-easier install
-ability to change maps from the module directly without having to buy any additional hardware

Jb4 Advantages
-more power
-compatible with all stages, fuels, and turbos
-safety failsafes that kick the car back to the stock map
-datalog
-read and delete codes

I haven’t tried either one but it appears Dinan (aka Holly) has outsourced this module to Racechip and slapped a Dinan sticker on it. Would probably be a better choice to just go with Racechip over Dinan. I’m leaning towards Racechip or BM3.

The hardware is the same, but the maps can be different.

Unfortunately, neither company share any details on their maps so its we can't know for sure
