Before i start, i just want to say that I've always been against diy mapping and loading free/cheap files obtained from the internet but..... I got talking to a fellow a3 owner today and mentioned that i was thinking about getting my car remapped. he said (as most of you guys have) that i wouldn't regret it and how it completely unlock the power of the car. He then went on to say that he did his one himself, I gave him my views on diy remapping but he explained that he didn't just buy as lead and download i file off the internet. What he said he did was.... he bought a lead for about £30 that he used to read and save the files on the ecu. he then sent these files to a professional car remap company that tuned the files and sent them back to him. All he had to do then was load the tuned files back on to the ecu. He said the good thing is that he can still load his original files (as well as the tuned files) whenever he wants. I know this wouldn't be good if you wanted a custom stage-1/2 map but would this be good for someone that was just going for a generic stage 1 ? I mean there's been a few posts about people send their ecuâs off to get remapped so surely this you be the same sort of thing and you would still have your original files should things go wrong? What do you guys think ?
