Update: I figured out why my RPMs were so low and the IAC wasn't adjusting its steps. My TPS in the Closed-Loop Idle PID Activation Settings, was set at 0.8. The actual TPS was 1.1 that day which meant that the CLI would never kick in when I was sitting in the car at idle. I re-calibrated it and decided to play it safe and set at 1.5. Today the car's CLI worked as intended. I am still dealing with wonky IAC which can be at steps 90 and barely allowing any air in. Also, I noticed that even if I select the MAT table to be used for reference, the ECU was still looking up the CLT settings. I posted this question on the msextra site, maybe it is a code glitch or this is how they designed it or I am missing another table. I might just use the CLT reference table and call it a day. I am posting the updated tune and the drive log. 2025-07-03_12.14.29-drive.mlg 2025-07-03-v104.msq

Thanks for Repairing my PassWord Problem. Is there anything that I need to do prevent this problem from occurring again? Toolman

Update: replaced the mustache bar bushings, re-torqued the strut lock nuts. I don't hear any more banging noises now. Still not sure what fixed it though. When I was checking my rear Bilsteins with springs compressed, I didn't feel any extra movements to give me that noise. I also swapped my master, slave clutch cylinders and clutch hydraulic hose. The old ones had some 'brake fluid sludge' inside from the internal leakage. I adjusted the clutch pedal at 8 inches (i have a carpet/sound insulation), the master cylinder rod of the replacement unit was the same length, no need for an extra nut. I could put the pedal at the max height (over 9.5 in) and the rod was still good. The free pedal travel is within specs, 15 mm. I was observing the operation of the slave with my $20 endoscope, 15 mm of the clutch pedal before the slave starts its movement. The clutch fork throw is half an inch (12.5 mm). I could push the slave's rod back towards the front, the rod gets back to its self-adjusting position. I did some searching - it sounds like 15 mm is a better number. My reverse and 5th get engaged without grinding noise and without any difficulty. The clutch operation is smooth. I used Rockauto's Luk's: LMC245 and LSC199 parts. Appreciate your guys' help. After fiddling with my closed-loop idle, I am still chasing my tail. I posted a thread on the msextra.com forum at: https://www.msextra.com/forums/viewtopic.php?t=82151 The RPMs get dropped very low, the ECU is not commanding enough steps for my IAC (or it is telling to give, for ex., 60 steps with not much difference). The car is driveable, but with rpms sometimes hitting low 300-400s, which is not good (CLI is not even running when it happens). Here is my updated tune and drive logs if anyone wants to take a peek.
