firstly (and off topic straight away) we need a non-make/model/engine-specific car-related section!! Mods feel free to move this if I've put it in the wrong place but I can't think of anywhere better to put it
anyway, to the point.
More and more people are fitting gauges to their cars these days, and fair enough IMO. But for the benefit of those like me who've never had the urge or the need, can we have a guide of some sort covering the following..?
What gauges are there on the market ?(eg types boost/water temp/volts etc)
What does each gauge tell you/indicate about your car/engine? (eg if oil temp is high/low then...)
Why do you need it/Benefits of having it?
What/Who is it suitable for? (eg boost gauges only for petrol turbo models etc)
i think this could prove really useful for people to understand exactly why they'd want/need certain gauges, rather than the how I feel it is at the moment whee people just fit them because others do (particularly boost gauge on turbo engines) without knowing the "how what & why" etc.
