Now that the ignition wire from the key to the ECU is hooked up, it actually stays powered up for more than 2 seconds. I can look at values in the ECU in RomRaider Logger. I was able to test the accelerator pedal, coolant probe (heat gun), IAT (heat gun), secondary air pressure (blow baby blow), and a few other things. One thing I'm curious if you guys have any ideas on is my throttle body, it buzzes. I know it's the throttle body because I can unplug it, and the buzzing stops. I homed all of the wires out, they all go where they are supposed to, and the only one that has continuity to ground is PIN3, which according to the wiring diagram just daisy chains to a bunch of other connectors, but Bob's drawings have it going to signal ground. Is it possible the unit is just bad, or maybe just dirty and stuck trying to return to zero? Possibly it's wired up wrong? See video for buzz.
