cheers for the responces guys
Unfortunately mine reads just under half for everything,cold,hot,volcanic.....its the second sender aswell, i know of 3 other guys with V8 and they all have this problem.
Its not that expensive at £25 and claims to be within 1 degree of accurate from mcgill motorsports, its a digital readout plus voltage(which is handy after a alty change and dual batteries upgrade)
What adapter did you use, i cant find one small enought (19mm i think)
I know what you mean but its gonna be better than what ive got at the moment lol
cheers again for the help
