Up for sale is my JB4 G5. The board is only about 2-3 months old. It is loaded with ISO firmware. I did not cut the resistors off totally, so it can be reverted back to regular g5 if you desire. I will include the BMS USB Cable, NLS/2-Step (No lift to shift, and 2 step rev limiter), and SLD (Speed limiter defeat). The harness is all wired up, so all you have to do it plug it in and go.
