My tacho appears to have gone a bit crazy. For the journey home it was on the end-stop. It did eventually settle down. When I fired it back up in Morrison's car park, it wound up to 8.5k again.
Anyone know what feeds the tacho? Is it the same as the ecu feed? The ecu is clearly seeing the correct revs, otherwise it would cut the fuel if it thought it was pulling those sort of revs.
