now you've mentioned that I do realise my observation that she is smart has been completely undermined by her lack of knowledge of heating systems. that's my new benchmark for smart, meaning my wife who happens to earn x4 what i do is now classed as a thicky pudding! COYH
Im sure your wife wouldnt sit in the cold dressed to go outside in the middle of winter but would actually manage to put the heating on boost/advance or something similar, I wasnt on about reprogramming the whole timming system
