Thankyou guys for the replys, done a lot of research on these lately and they seem very good old skool ecu's not after big power, just enough to know everything's safe, Daniel mate if Scotland was a last resort I would be up there 👍🏻 Amjad thanks for telling me that Essex isn't too far from me being in sussex, I'm trying to find out prices aswell, as it needs hardwiring in too, (shame you can't get a harness for this) it apparently has a 400bhp map on at the moment, so if I did get it hard wired in, would the car last till I got to the mappers if driving off boost of course (also got a wideband in to) to keep an eye on things
