So this is my experience of ECU Express. I first entered a search for ecu repair in my local city. They appeared and their website looked very professional, a clever use of search keywords as there is no ecu express in my city. I messaged them and got a text reply with the service they offered. I telephoned them and the gentleman said I needed to get it to him before Tuesday as he is going abroad on Holiday for two weeks. I sent it immediately and it arrived the Friday before. Payment of £60 was requested, I paid immediately. I got a call on the Monday saying that my ecu was not repairable and he suggested I buy another one to clone. I decided to look into that. So it soon became apparent that these are upwards of £200 with no assurance that they are in good order, then there would be further unknown costs to clone. It was all too risky for me. I decided to wait till after he returned from holiday and have him return my ecu. I texted him asking him to contact me when he is next available. He returned from Holiday on the 5th Oct. I waited till the 16th Oct as I thought he would have to quarantine returning from this country. I then rang asking him to return the ECU. It then took a further 5 calls and 3 texts to finally get the man to return my ECU, I received it on the 28th Oct. My assessment of events is that; I received no test report. I received no invoice I have no way of knowing if the ecu was ever tested or even opened up. I feel a service should be offered where they source and supply a unit to clone and quote for that accordingly, not to put the responsibility on the customer. He told me he doesn't do the testing but he has to pay another firm to do the testing. I hope this helps you make a decision before sending your money into this gentleman's holiday fund.
