    Electronic throttle on 2003 express van?

    I have a customer who's doing a 5.3 swap into something and dropped off his ECU for a bench flash to get it going. On the notes left with it one of the items says he has as drive by cable throttle body.

    Looking at ECU I see electronic throttle control options. However I know those options often exist in the ECU even if the car wasn't ETC from the factory. So how do I know if it was in use in stock form or what to change? if anything? I'm not exactly up on my Chevy Express Vans lol

    2003 Chevrolet Express 3500, 6.0 L, 8 Cyl
    P59, GM Gen3 V8, 4.3L V6
    OS 12579405

    Thanks

    A 2003 van is going to be cable throttle body.

    You can click the system tab, then system options and the ETC row should be a zero on the VAN platform.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Thanks for the tip. Strangely every column there is a zero. I can't tell if this is stock or been modified as the tune repository on HPT home page is gone with no ETA of coming back

    See attached screen shot.

    Looks normal for a 2003 VAN calibration. From what I know they didn't start using the ETC until like 2005-2006 in the vans.

    2003-2007 trucks used drive by wire though.
