cheers fella, i was under the impression it was gona cost about £400 for the ECU then a further £300-£400 for the map, thats just taken a whole lot of worries of my mind!!!
the ecu itself is only something like 150 but you have to add on the extras which is why the unit with all the harneses etc will cost £355 and then you need to add about £300 for fitting and mapping.
