I have a ESP data logger, based on a hp palm top pc "included". it can tell you your 0-60 times, tells u your bhp, can read and delete fault codes and data logs. does tons of other stuff, i bought it from here a few week ago for £150 but ive had a new battery fitted. so looking for £175 ish ono. i would swop for any thing of interest. i'll post some pics in a bit. cheers paddy
