Got it hooked up but the readings make no sense. At idle it's telling me that the MAF is 0, the LV8 is 30 ish, volts are 0, INT is 0, BLM's are 0, speed is 72 mph (I'm sitting still), coolant is -40 (it's 80f outside), air temp is 0, rpm is 1625 (more like 800), tops is 5V, IAC is 0, 02cc is 0, and no codes.
