From their website it says..........
If you require technical assistance, this is chargeable at £23.50 per 15 minute intervals (e.g. if 20 minutes is spent, 30 minutes will be charged). Please call 0208 391 0121 stating that you require technical assistance for pin-out & wiring issues. Have your credit card details readily available.
When purchasing second hand ECUs, please note the following;
If the ECU is still a current issue i.e. advertised on our web site, it can be reprogrammed, costs from £90 per unit.
If the ECU is an older model, it is recommended that the ECU be only used for the type of engine it is already programmed for. If you require an older model reprogrammed, costs are from £125 per unit dependant on the age of the ECU. It can cost more for the unit to be reprogrammed than the purchase of new ECU. In addition, if the unit breaks, the older units (e.g. 912-900) are irreparable.
Testing/Repair of Ecus
If your Ecu requires testing and/or repairing, the ecu must be sent to us with full details of the fault.
Testing only costs from £90 + VAT: Testing & Repairs costs from £150 + VAT
