Default Can I adjust for moving idle speed?

When I have the clutch disengaged and am moving faster than 30MPH the idle will stay around 2000 RPM's. As soon as I get to about 10 MPH it will drop back to the normal 1000 RPM's. I plan on getting HP Tuners in the near future. What would I adjust to get it to idle lower in that situation?

log your STITs and LTITs, your base airflow is likely too high, though it can come from the throttle cracker table as well.

No link that I know of, the link posted earlier in this thread has airflow descriptions though. Just log them at hot idle and see what they are right now. Make a change to your airflow at current temperature that reflects the % of the two combined trims. Sometimes I will take the % change and just apply it across the board as a starting point as well for the other temps. Remember after changes that idle trims learn very slowly, so give them some time.
