The JB4 will clear the limp mode off the dash but the ECU still keeps itself in limp mode until you turn the engine off/on cycle.
I did some experimenting by logging in limp mode and it seems like the ECU keeps the car from boosting at all ... JB4 still asks for correct targets just get no boost - There has to be some way to reset completely but I haven't found out how yet.
JB4 is defiantly worth it ... I have been running around on the E30 map and am quite pleased
