Alright so I had this great idea today.
I never use my stock headunit I've probably turned it on maybe 3 times. So I was thinking that it would be pretty cool to have a screen in place of the stock headunit that could display data such as boost, egt, a/f ratio etc. Is there any kind of computer set up on the market that does something like this? I looked at some of the carputer threads but most of them seemed to be primarily for music and what not and seemed incredibly complex.
