Well, it's not all that new, Darren Dawes has been making these for the past six or seven years now. He started making them for the Shelby Dodge community back then, and since then sold them to a wide variety of interests.

Check it out. I expect to use this.
You can make the exact same thing with $5 worth of parts from Jameco or Digikey.
Its cool, but he says that it only works at WOT... Most of the driving I will be doing (Once my turbo is in) will not be anything like that. I like to know where everything is at at all times, not just at WOT... Thats my 1.5 cents.
I think then you need an EGT meter with alarm feature.
sorry to burst ya bubble but thats shit eh, narow band o2 sensors output is of very little use it tells you rich or lean side of stoic but the exact amount is not acurate (don't tune with one). You realy need wide band to tell ya any usefull info. The led bar graph like that is easy to make if ya realy want one i'll put a circuit up for ya.
