    What are the units Row ETC Driver Demand Engine RPM vs. Pedal

    Hey I'm trying to work out a surge in a 2012 GT500 that I believe is caused by a little bit of roughness in the driver demand table.

    I'm trying to log the right accelerator pedal pid but none match the numbers in this table. I assume they are ADC counts but what is the conversion? 0-5v = 0-1024?

    I can confirm it's counts, but I could't say if the 1024 conversion is accurate. Technically is looks right, but I would look for a more knowledgeable source to confirm it.

    pedal WOP enable 1026 bypass the driver demand and goes to the inverse and torque tables under torque management

    Your conversion is pretty close.

    I'll get the channels added for logging this in A/D Count ASAP

    I've been multiplying my Accelerator Pedal Position voltage by 204.8 to get the AD Counts. On my SHO, the pedal at WOT is about 4.10 VDC so it converts to about 840 AD Counts. It's actually 816, but if I jam my foot down even more, I can squeeze out a few more AD counts.
