Not that important, but if anyone has an idea on what causes these apparent AACV activations, I would be very interested. It seems to happen when the engine is coming up to temp only and not just once. From what I can see no variable change to make it happen.

Thanks Matt. I tweaked the injection latency up a bit. Lifted the Min Load by 1. Set the idle to 825. But the thing that made the most difference was lowering the AC on AAC duty from 19% to 7.5%. Now it only increases the RPM and decreases the RPM only slightly when going on and off. Still a bit lea...

Not sure how to fix this, but when the A/C is running and the compressor automatically switches to off, the RPMs drop to almost stalling and hunt, finally recovering to normal. When the compressor is engaged, the RPM rises a little then goes back to normal.

Thanks Matt. Good to know. I doubt I will stop fiddling with it.

Thanks for working on the update to see the switches, that's awesome. I made the changes to the 'MAX load (TP) Decel' table, but I don't think it made any difference to what I am looking at, which is the super high AFRs on decel. But from what I have since read, it is normal to be high. Does it look...

Since adjusting the TPS threshold, it seems to run more lean on decel, like off the scale. Is this healthy? Is there a way to give it fuel on decel, or should I? Is it normal to have the TPS Idle on when deceleration? I have attached a log and my bin. The ramp starting at 8.600 is the point of inter...

Thanks Matt. I did not notice the idle indicator was not on. I have adjusted the parameter and now it idles nicely.

Thanks for the tip. I have discovered that if I pinch off the PCV hose (inlet cover to the intake manifold) the idle drops way off. Doesn't seem to make much difference on the other breathers. So I bought a new PCV and the grommet, but that did not help at all. Not sure what is going on.

RB25det with the R32 RB20det ECU. It idles, when warm, at about 1,100RPM. The AAC screw is all the way in, the throttle is closed fully and the TPS reading .45v. AC is not on. I tried playing with the Idle AAC Duty which I could bring the idle down to a nice 850 by adjusting the warm columns down to...
