I just saw a few movies onver the web about the R34 skyline. http://www.youtube.com/watch?v...earch=

there is a computer inside and showing all the parameters in BAR graph graphics. I already have ECU Control on my Carputer and i'm wondering if there is anything else that exists that shows (do not need to modify) real time parameters of the car ?

 

Bad link and gredy and apexi both make infometers. I think the greddy is a newer design and the apexi is a rev-speed meter which is more or less a vafc/safc with no ecu modification controls.

 

Take a look at this http://www.brockwayengineering.com/.
