So I'm fixing the tuning on a 408 Texas Speed combo for a customer.
Previously would die coming to every stop light.

Anyway, before I go nuts, am I going to need to mess with the IAC steps vs Idle effective area?

It's an auto trans car. I added some follower, which works but is a nuisance.

The whole tune was whacked, so I haven't got to go through Base Running Airflow yet. Or a cold start.

Just a side note, IAC is now near 0 hot idle.
When the IAC opens via the follower, it makes a tremendous noise through the air filter.....like it whistles........
Throttle volts is .45....that seems really low.

I figured this out.
Started right up cold this AM without touching the gas. A first for this car since it was built.
I was able to get good proper BRAF data.

On to the rest of the tuning.
