my god, you my friend have completed my senior design project, sort of..
but yeah, I wanted to take a 20x4 lcd and interface it with obdII on a GM truck, to display information..
does your setup use a computer? or is it just wired up to the connector itself..
please more info!
its been awhile since I've been around here, but I think im gonna have to get back into this.. my 95 blazer has one of the first obdII systems.. computer in the engine comparment, and obdII connector under the dash, hopefully this will work, or else ill be force to work on the pops blazer.
