Hi not to put to finer point to this, why would anyone buy a fifteen year old car thats been mapped, I can only assume that it must have been an attractive proposition to you at the time, have you any idea how much extra power that map produced, do you know the original mapping agent as most companies that do this process properly cost a lot of money because they do things like delete the original map but back it up in case of future problems and use one of the other map paths in the ECU, I have even seen case in point one of my neighbours sons with a year old Vauxhall Corsa that his dad had bought him so he could commute back and forth to university, tops up one of his computer sciences mates had lifted a remap off the internet and installed that, junior mentioned none of this until a rather irate engineer who had diagnosed the vehicle came out and informed his dad that they can't fix the car under warranty because it had been interfered with which voided the warranty, end result was a new ECU £2000 plus fitting, there are so many John Wayne mappers out there it makes me cry, why do you think most automotive software writers are on about two hundred grand a year, anything outside that and the people are just playing at it as they don't get two years testing and a Dyno set up to fine tune what they have written.
Steve.
