Close Delay set at 1 sec; Leave Valve Closed Above 1000 RPM; For the # of sec = 3
So, 1 second after you leave CL idle plus about 200 RPM, your idle valve will close. Then, as in during a shift, you go back to closed throttle, then, after 3 seconds OR RPM falls below 1000 RPM, the idle valve opens to the target value. This is needed to hold RPM up until CL can be activated.
In this case, it looks like you *EDIT* hit the 3 seconds.
i.e. it is doing this because you told it to.
*EDIT* 1000 RPM seems low, as it is real close to idle.
Closed-Loop TS indicator = (MLV status2=128) ?
Closed-Loop MLV status2=128 only when PID starts?
Closed-Loop Idle Valve Settings can take effect when PID is not active ? (TS indicator off / MLV status2=0)
I don't know about your first 2 questions, but they are good ones, and I too would like to know what all of those status and port values mean.
But to the third, yes, and that is what I tried to convey in my first response. If you set the Closed Delay to "0" in the section I referred to (Leave Closed.... etc) then the Idle Valve will stay open all of the time to exactly where your target table tells it to be. Cycle the ignition off and back on for this to be stabilized.
Then there is no, why is it open, why is it closed. It will always be open and ready.
I think your issue has to do with the max decel load% value.
on your log screenshot, you're idling well below 29 MAP (most people idle closer to 30-32MAP). That value should be tuned to be just a few points below what you typically idle at. It appears once your vacuum drops below that threshold it finally enters PID momentarily, after the 5sec delay you have set. Otherwise the car wont enter into PID unless you've breached the max load, and then come back above it.
I'd tune the max load value better, and try a delay of only 1sec. That's what I always used with much success.
and then I'd actually close my TB screw so the car actually enters RPMs in which the MS will control idle at. Right now your idle valve isn't doing a damn thing at 20%PWM or 60%PWM.
