Would it be possible to install and use Aftermarket guages?

oh yea and i need an ac compressor just in case any one dident ceatch my other post about the ac compressor

1982 to 1992 Camaro's and Firebirds would be about the easiest, since they have a very flat area for the insturment panel.... I know I could get something wo work on them after the hardware and the software I/O problems get figured out...... thats something else I just thought about..... how to get the info to the brain box to display all this.... would it be better to splice into factory wiring, using factory sensors (after finding out their parameters) or just getting all aftermarket parts and making my own sub-system for the display by having redundant sensors?

Very true. I don't dispute your point. Just basically all of the speedo's I have seen are 160mph..... and if I were to get an aftermarket, I might as well get it. My main reason for posting though was how or what would be involved with getting like an electric AutoMeter speedo to read corectly on our cars? If they make any marked out slower than 160, atleast in the styles I like, I am unaware of them (which is possible.)

An autometer or other electronic speedo *should* work fine with the 4000 pulse/mile signal... I was looking through the summit catalog the other day and they had some interesting digital gauge panels

Cool. If I can find all the electric parameters on the stock sensors, I'll just use the ones that are on the car. For now, I'll try to use a lap top. How am I going to get the lap top to interperate the signals from the car? I need some help on designing a custom made box to take all the signals from the outputs going from the ECM to the Instrument Cluster, and turn them into a serial input for the computer. Once/if that can be done, I'd just have to write the program to make sense of the inputs..... after thats done then I can try to get the guages to work and design a GUI. After all thats done, then its time to simplyfy the program down as much as possible, so as to get it to run on a non-boot all intergrated circuit board. This could be fun..... lol
