Below is on a 98Z28 A4 using EFILive

Today I played with this table in an effort to correct a warm starting problem and it seemed to work okay. But…
The problem is that when you transition from park to drive or drive to park it seems that the values in {B4343} Startup Friction Airflow Correction table are also added to the {B4703} Desired Airflow table and the IAC counts jump up and as expected the idle increases.
I thought that the values in {B4343} were only applied at startup and for a very short time afterwards as controlled in the {B4344} Startup Friction Airflow Decay and {B4345} Startup Friction Airflow Delay tables.


Does anyone have any experience with the idle start-up tables?

Thanks

Any feedback on this?

What is your startup issue?

 

I am trying to get a little but more air through the IAC on startups without adding it to the running airflow table.

 

Right, but what are you trying to fix? Maybe that's not the best solution.

 

If I set the running airflow (desired airflow) table to a value that is high enough for car to start and run it ends up being too high and when I go to park/neutral from gear the engine races.

John, after porting your TB did you redo your IAC effective area table?
