[quote][i]Originally posted by Dave A[/i] ed, you are missing the point. yes, all cars come with a generic map from the factory which is very safe (hence the gains you see from remapping) but as soon as you start pushing more power through the engine and ancilliaries then you need to monitor what exactly is going on, more so on petrols. sending an ecu away for a remap is a bad idea, before you remap an ecu you MUST check the outputs from each engine sensor and check for fault codes, without doing so you are mapping over various possible problems, if these problems ever result in a light on the dash and they get repaired then the map wont compensate for these changes. I have used flash remaps, not yet have I been exited by one, they simply cannot take real life driving into account in the same way as a custom remap that is written on the dyno and finalised on the road and mapped live. many flash remaps are simply written on a laptop and boost and fuelling is increased throughout the rev range, with no changes made that take throttle position or load into account, this can ruin drivability and fuel economy. I have used about 30-40 flash generic maps on cars from various manufacturers and some are good, especially those written by Revo and Angel Tuning, but most are just rubbish. If I could charge £150 for a flash remap, no dyno, no work gone into it (apart from plugging a laptop into a diagnostic port and uploading an unkown file) that takes 10-15 mins, I would do so all day everyday. Fact is though, nothing beats a live remap that is written on a dyno and then road tested. its not all about how much peak power it makes over standard, its about what happens between 1000rpm and peak rpm. why risk a car worth thousands for the sake of saving £200?
