Default LS2 Throttle Body--88% open = max?

Question regarding the drive-by-wire throttle bodies:

When logging I noticed that when I go WOT, the scanner is detecting the throttle at 88% open. Additionally, when I let off the gas, 'closed' position is interpreted as 19%. Is there any way to calibrate the ETC?

TIA...

-Jason

from what i understand GM interperts TPS position differently...as far as close position goes you have ETC and no IAC so the TP is partially open to keep your car idling as far as I know.

Ahh...good call on the IAC thing. I would assume that it needs to be somewhat cracked then.

Sounds good. Just get with me when you have the extra time. I see you have upgraded the TA to a nice new GTO.

Just a question. If the plate is 88% done with its complete rotation doesn't that allow almost all of the possible airflow?
