How to get AC idle up to work on an NB
Can someone point me to where I can find how to get the AC to work on a 99 Miata with MSPNP Gen 2. I’ve searched and I couldn’t find anything from recent years.All I found was for older Mega Squirts and older versions of tuner studio. The only reason I got the MS over the others was because they said it had AC control and no AC is not an option for me.

My car is weird about idle pwm duties. I wouldn't advise copying the settings. Just showing you where it is. You can also always search in the top right of Tuner Studio if you are unsure where something is.

This are all the options I have there
And I already tried every option there. I even went to the IAC settings to see if changing it to Closed-Loop would help but it didn’t
Thank you for the input that still helps because I'm completely new to this. It'll help me get started when I find where to turn up the idle.

TunerStudio MS v.6.19
Innovate MTX-L Wideband O2
I want to install a Turbo in the future and I’m beginning to learn about it in this site. And from what I read people advise to get the MS up and running before starting the actual build. And that’s what I’m trying to do. I Installed the MSPNP2 and the wideband and adjusted the timing as the instructions said and even with the base map the car ran better than ever. I never thought it would make such a difference. This is the only problem I've had so far.

from the MSPNP G2 manual:
Air Conditioner Idle-Up:
The AC Idle up feature allows the engine idle speed to be increased when the AC compressor is engaged...The input to be used is jumper selectable and is set by default to Table Switch (PE1).
...
Idle up input: The default setting is Table Switch, and while most users will never need to change it, this setting allows advanced users reassignment capability of the MSPNP's I/O as to better suit their vehicle if needed. The input pin selected here must correspond to the position of jumper set 3, as shown in the jumper selection table below. This allows the user flexibility in choosing the I/O needs for their application.

I tried Open and closed loop. But I’m a complete Noob about this. I tried the CL values that came with the basemap.
And the MS has a green board. And if I remember well it also had a smaller white board to the right of arrows 10,13,16 of the picture above. I just ordered lake 2 weeks ago.

Ok. I just realized I haven't used any of the optional ports on the MS. Since it is a MSPNP as I mentioned before. I thought it would was supposed to recognize the signal from the stock harness. Do I have to wire a signal input to the optional port "Table Switch" or "Launch"? If so how or where can I find the proper wire to tap? I've read people say something about using the compressor clutch and others the fan relay. Sorry for all the questions but as I mentioned before I'm a total noob.

Try enabling Port Status under Project Properties, then make a data log of trying to activate the A/C idle up and post it along with your MSQ. This will show if you're actually getting the signal into the unit.

Got it to work. (Kind of)
***Now I just need to find the “Compressor Delay” on TunerStudioMS v3.0.05 to adjust it. Does anyone knows where to find it?
