Ive got a techedge kit ive been using for this sort of thing for years, and it uses a honda item for the actual wideband sensor.

Dan, cheers for the offer mate, might take you up on that as sadly if i jump in it and say to cally "give it death" i will end up trying to map it while she does donuts as she has an obsession with doing them

Last time i let her loose in the rwd nova in an open space i had to get the RAC to take it home cause she popped both the rear tyres
