    Idle switch always 0 in evoscan

    I've been going through the chromedecu getting started guides and got to the idle section. I noticed at idle that my idle switch was always reported as 0 by evoscan.

    I've performed the following tests:
    - rotated the throttle position sensor fully forward, and fully backward without seeing the idle switch change state in evoscan
    - measured the resistance between pins 3+4 and found that the switch opens correctly when i rotate it clockwise (see here)
    - manually shorted pins 3+4 on the harness side without seeing the idle switch change states in evo scan
    - measured 5v between pins 3+4 (so its connected to the ecu probably)
    - the tps reports a value of 13% for the throttle position at idle

    I haven't tracked the wires down to the ecu yet to verify, but does anyone have a guess?

    It's going to be Evoscan... Set your idle switch to request BA, X bit 1.

    I bet it's set to X bit 128...

    You're right, it was. Is that an error in the xml? I just downloaded it from the chromedecu site recently.

    I guess... Seen it several times. Greg pointed it out and gave the fix in this thread:
