This service will enable engine start if the May & Scofield alarm module fails. Prior to refitting your bypassed ECU, disconnect the May & Scofield alarm module and create a bypass to the starter motor relay to allow the engine to crank. We will carry out some basic DRB3 tests on your ECU, including correct power-up and main relay control, prior to processing your ECU. Turnaround will normally be within two working days.

After you have made the payment, please send us your ECU, vehicle details, and a copy of this purchase receipt. Alternatively, if you need to know more, please start a ticket and include as much information about the problem you have. This makes more sense than making a purchase without knowing if it will help you.
