All,

I just installed a DIYPNP in my 1995 miata and I'm running into a closed loop idle issue. I've gotten it idling nice and smooth with stable AFRs (13.0) and 14deg advance from 900rpm (target warm idle) to 1300rpm (target cold idle). With my current settings, it goes into closed loop idle and stabilizes nicely at 900rpm upon startup, but after ANY throttle application, it does not go back into closed loop when it comes back down in RPM. It'll still idle pretty smoothly, but there is definitely no PID action taking place. I have played with all of the closed loop activation settings to no avail. I'm hoping someone can point me in a direction of something I'm missing. MSQ file attached!

Thanks in advance!
Rob

 

Welp, I figured out my bonehead move-

I somewhat misunderstood the load threshold value and had it set above my normal idle MAP *facepalm*

I would've caught it when I was playing with the activation settings but I was too impatient to wait the 2 seconds for CLI to activate. She's idling pretty smoothly now!

As a side note but is it me, or are some of the settings in Tunerstudio named VERY poorly?? For instance, that load threshold is shown in % but is obviously a kPa value. Is there anyone to send suggested tunerstudio changes to?
