Aidan Duggan Motors

Independent performance and diagnostics garage specialising in ECU mapping, Link ECU and ECU Master standalone management, advanced diagnostics and selected transmission work. ADM has particular experience with Toyota and Japanese performance cars, alongside modern Volkswagen Group vehicles, DSG transmissions and BMW diesels.

Why we recommend Aidan Duggan Motors

Finding someone to map a modified car properly involves more than simply booking dyno time. The condition of the vehicle, supporting modifications and any underlying mechanical or electrical faults all matter before calibration begins.

That approach is one of the reasons we're comfortable recommending Aidan Duggan Motors. Aidan prefers performance cars to arrive properly prepared and mechanically sound before mapping rather than attempting to tune around existing problems.

Toyota is a particular strength on the Japanese side of the business, with ADM regularly mapping Toyota performance cars alongside selected Nissan and other Japanese models. Link ECU and ECU Master are the two standalone ECU platforms Aidan works with most, with stock normally held for both. MaxxECU is also supported on a smaller scale.


Beyond Japanese performance cars, ADM has substantial experience with modern Volkswagen Group vehicles, including diagnostics, ECU/TCU mapping and selected DSG mechatronics work, as well as BMW diesel tuning and automatic gearbox servicing.

For owners looking for proper diagnostics before parts are replaced unnecessarily, ADM also has access to manufacturer-level and professional diagnostic equipment covering a wide range of vehicles.

What stood out to us is the emphasis on having a car mechanically ready before it goes onto the dyno. For owners building or maintaining performance cars, that distinction matters.
