In HP Tuners in the engine section (for automatics) there are airflow adder tables for when changing between gears but I cannot seem to find this. How can we get this added?

I'm not quite sure what you are looking for, but....


{B1829} Minimum Idle Airflow: Sets the minimum closed throttle air flow for each gear, set in RPM steps.

{B1827} Shift Into Gear Compensation: Idle airflow compensation when shifting into gear, increment amount. Set in ECT steps.
{B1828} Shift Into Gear Compensation, Ramp Out: Ramp out rate for the Idle airflow compensation when shifting into gear. Set in ECT steps.
{B1858} Shift Into Gear Compensation, Hold: Amount of time to hold the in to gear idle compensation before ramping out the additional idle airflow. Set in ECT steps.

Those parameters appear to only be available on very early E38 and E67 OS ... looks like these may be limited to the 2006 model year.

Pulled the file with HPT and they are available. This is why I asked

{B1829} should be in all OS's

Given I drive a manual, I don't care about the rest :pokey:

So you have worked around the issue?

Yea, tuned it with HP Tuners:wallbash:

At this point, its not worth using EFI as its missing so many ECM and TCM tables

Yes sir it is ... my comment was specific to the original question regarding airflow for gear selection.
