CL idle IAC, following CL idle init table ?
Can you please just point this one out for me ?
If I use CL idle init table, the CL idle target RPM will use this table always ? or just as init value after throttle lift ?
Example:
On a normal drive when I leave the throttle paddle and CLITR is 900, will the CLI take the IAC value from this table or will it adjust the IAC until CLITR reached ?
Does it change the IAC value until CLITR is reached or does it uses the table in order to "know" what IAC value to use in order to get to a specific rpm.
Hope I'm clear enough.
Thanks !

Re: CL idle IAC, following CL idle init table ?
The "initial value" table is just that - when the code detects that you want to idle it will grab the value from the table and then use PID closed loop to achieve your target RPM.
You get to tune the initial value table to give you a valve position that is the best guess of what you need.

They are two different things.
The initial value table sets the valve duty (or steps) for a given target RPM and temperature.
The target RPM curve sets the target RPM against engine temperature.

Re: CL idle IAC, following CL idle init table ?
Thank you for your answer James but you I think maybe I don't explain myself good enough, let me try again.
If CLITR is 1000rpm, in order to get there the CL needs to change the valve position - right ?
If so, will it just change the valve position independently and will "find" the right duty value in order to get 1000rpm ? or does it follow anything else ?
The init table say that for 1000rpm you need lets say 40% valve duty(@ 90C), does CLITR will "find" this value on its own or does it use anything in order to "know" what duty it needs for 1000rpm...

Once you enter idle mode, the code grabs your 40% from the table. It then adjusts the valve duty as needed to achieve your target RPM - that's what closed-loop means.

Thanks James, I guess I got it all tangled in my head...
