ECMlink Idling at 2000-3000 RPM with AT D pin off

Been wondering about this for the longest time. My DSM is an automatic with a W4A33, and whether it's cold or at operating temp the idle always stays between 2000 to 3000 RPMs when I have the transmission in park or neutral. Is this normal?

No that is not normal, I to have an auto and my is holding the proper rpm , you should check the isc motor .

My car idle around there when I didn’t line up the two prongs into the tps correctly when reinstalling it.

My vote would also be ISC issue or BISS. Can you post a log?

I’m gonna be playing with the BISS/ISC today, I’ll get a log of it and post it here after I’m done

Has ECMTuning added support for automatic transmissions to the idle control in DSMLink? I don't remember them having that so the idle in Park/Neutral should be the same as what you set if the ISC/FIAV/BISS system is working.

As far as I can tell they haven't added that. Maybe they'll add it when they finally come out with V4?

Anyways I figured it out, it was my idle switch not activating properly. Just adjusted my TPS and it's all good now.

I was going to mention I have seen with autos when the TPS is out of adjustment it seems to cause more idle issues but you figured it out!
