My 2003 Alfa 147 GTA wouldn't start with an 'Immobiliser' fault appearing on the dash. Removed the ECU and sent it to ECU testing. 3 working days later it arrived back to me in Dublin. Fitted back onto my car and the car started straight away. Fantastic quick turnaround service. 10/10.

Top service, very easy to deal with.

Always a great service, fast turn around and delivery. Great business

Always helpful and offers a good honest reliable service

Most websites never respond to a request or questions, but ECU testing did. From beginning to shipping the part to repair and getting it back- was professional every step of the way. I am in California so was even more impressed as some services won't help you if you are not in the UK. Sadly, the "only" possible competitor for my repair was in the USA and never heard back from them. So highly recommend ECU!

very good and quick service.
