By far the best repair business by a mile, I've used ECU Testing pretty much from when they started I have never had a single problem with any repair they have carried out, I have been in the motor trade for 55 years and in the diagnostic business for 50 years I wouldn't hesitate to recommend their work to anyone, they are my first choice whenever I need a ECU repair of any description.
