I was trawling my way through Ebay the other night and I noticed a company offering a remap with a decent power hike. The only thing was you had to remove your ECU and post it to them. It was fairly cheap, (99 quid) but not so ridiculous it seemed to be untrue. So I was wondering if anyone had any experience of doing similar?
My first concern would be removing the ECU. How big a job is it?
Second concern is if I did remove it and post, would there be a chance I wouldn't get it back and what would I do if this happened? Can you replace the ECU?
