the instant economy would be effected by the # of cylinders

thanks to paul (1997chevydriver)i will try to wire mine up tomorrow and find out i guess

Also I'm not so sure that there are any "calibrations" in the DIC unit. Mileage, Range, Ave milage Gals used are all relayed from the computer on the truck.

That's what I was thinking to. Its just a display I figured. If you guys are showing around 15 mpg on there it should be right. I can't wait to get mine hooked up, but its gonna be after I get this car finished :(

Looking thru the OP I realized I had missed what wires did what on the DIC so I added wiring pinout pictures to the end of the OP to include radio plugins, OBD II connector, and DIC connector.

the wire colors for this unit are a little different, #15 is purple instead of yellow, #12 is brown instead of purple/white,#7 is yellow instead of dk green, it must have come from a bravada since that is what i have seen on the net to have these color wires in those locations

Are the functions of the wires the same though? or are they different than what I had posted?
