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.

For 2014+ BMW motors that have an (EWG) electronic wastegate. This add-on patch allows your JB4 to directly control your electronic wastegate raising the boost ceiling and tuning flexibility.

The new EWG harness has two long wires coming from it. Purple and blue. Each will have a gold DSUB pin which is to be inserted in the JB4 harness similar to how the FlexFuel connector is added. Put these wires inside the rubber wire grommet going to the large DB25 connector on the JB4.

3) The purple wire (going to the male pin on the wastegate harness) connects to position #9 on the DB25 connector. Carefully push in until it clicks.

4) The blue wire (going to the female pin on the wastegate harness) connects to position #16 on the DB25 connector. Carefully push in until it clicks.
