    DBW pedal voltage adjustment?

    Hey guys.

    I'm starting an LS2/T56 swap into a BMW Z4 and would really like to reuse the BMW gas pedal (it is DBW). Is there a way to adjust the 0%-100% input voltage in HPTuners? I have never done DBW tuning before (had a 2001 Z28 with cable throttle) so I don't recall seeing a table.

    Thanks,
    Chris

    The BMW gas pedal won't work. You will need to match the APP (gas pedal) to the controller you are using. If this is an early LS2 with 24x CKP - then you will probably use a P59 controller - in this case you also require a matching TAC module. If this is a late LS2 with a 58x CKP - you can use an E38 or E67 - as long as the TB (throttle body) and APP are compatible with the controller OS.

    Thanks. Guess I'll just convert to the older BMW cable drive pedal and use the F-body TB.

    You will have to use an LS1 PCM and not an E40.

    Thanks, yeah I'll run just use the older F-body PCM as well. I was only looking at the Vette PCM/TB in order to reuse the BMW gas pedal. If I have to switch pedals I'm actually happier using the F-body PCM as I have unlimited licenses on it.
