Rich, it also struck me that rather than truely wanting my opinion Christian was just engaging in some sort of childish "get internet revenge" thing with this thread by trying to show I dont know everything (which would be pretty pointless as if he wants to show that he only needs to ask me if I know everything and I'll reply "no I dont" as ive never claimed that anyway)

But I decided to instead just take it at face value that he wants my help, so I think you should do the same.
If he does want my help then its just a shame I cant give him any beyond a few guesswork suggestions as I have never been in the situation he is now so have no experience of how to find the pinout on a map sensor sadly which is a shame as I would of course help him out if I could.
