For years, I haven't been able to achieve the idle RPMs like I wanted in my truck. Finally, I spent a couple hours this evening playing with the tune. No matter what I do, something is commanding the idle RPM to be 150 RPMs higher than I have commanded in the Desired Idle Speeds table. This is true for the RPMs in all four columns. I played with every table under Idle -> General. I finally gave up and lowered all numbers in that table by 150 and it finally idles where I want it to. In other words, I have to command an In P/N A/C Off RPM of 500 in order for it to idle at 650 RPMs. What gives?
On another note, I've had issues with the A/C not wanting to run at idle ever since I put this mildly cammed LQ4 in here years ago. That's why you see all my A/C on RPMs as high as they are. Even at 1100 RPMs, it still sometimes doesn't want to keep the compressor on. I can't find anything in the tune that would cause this. Any ideas?
