Expert ECU Repair. Specialist diagnostics and postal repair service
ECU failure does not have to mean a £1,000 or more dealer replacement. Our Bournemouth-based specialist team provides comprehensive ECU testing, board-level repair, EEPROM cloning and replacement programming - with postal options for customers across Dorset, Hampshire and nationwide. Whether your engine management unit has suffered water damage, a failed voltage regulator or an immobiliser sync issue, we diagnose accurately and repair cost-effectively. Customers from Poole, Southampton, Wimborne and Ringwood use our workshop and postal service to avoid main dealer lead times.
We also support marine ECUs recovered from outboards, inboards and PWCs — salt-water corrosion and connector faults are common. Pair a repair with a fresh Stage 1 map via our Marine & Powersports hub.
