No, I specifically asked them that, which is why I removed it from my car. It is compatible with the Stage 1 JB3 because it does not rely on the CanBus for its information. However, the JB4 does and although I did not notice any problems while using both the folks at BMS assured me that the two are not compatible. Which is why I am selling it. I will take any reasonable offers and it is in great condition.
