Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

The BMS JB4 Failsafe Box (FSB) Water/Methanol Injection (WMI) controller allows the JB4 to control your WMI pump and solenoid for dynamic progressive flow mapping. It also allows the JB4 to monitor pump current to overlay it with CANbus feedback for tuning parameters such as fuel trims and fuel pressure to provide a comprehensive flow-based safety system.
