Hey guys I've been searching to see if anyone has made some external usb/another external source car gauges such as a tach, speed, and fuel. The computer could use the GPS to find the speed and have some input devices for fuel and tach.
Has anyone heard of such a thing?

Dead recking GPS would be good. Plus, dead reckining GPS adjust themselves based on the speed sensors in your car.
OBDII for tach and other stuff (temps). I don't know if OBDII supports fuel % left.
I did. My pic-based circuit is measuring the rpm, speed, accu, distance, temp in/out and so...then passitng the results to the PC via parallel port.
I use the digital signal that goes to the instruments, eg: speedometer or tachometer.
confused, then what are you asking?
or u could just tap into the ecu and display it on your screen......
Just think about how cluttered that would be. And plus gauges look better.Originally Posted by SmoL

well you could write a program to get the signal from the ECU and output it into a "gauge"
Ya, it's called a stack display, and it AINT CHEAP, and not really a straight OBD.
With a car, you have evertything you need IN YOUR DASH. Why would you need a speedometer, or tach, or fuel when that is already there.

because some people want to replace stock gauges with a display driven by a pc
