My recently modified LS1 was built with a Fast92, 90mm LS2 TB, Comp Cam (231/242 .617/.593 112 LSA (14 deg. overlap). It made 450 rwhp on a loaded Mustang Dyno (92 degree ambient temp day). It runs like a beast on the track. It drove like ass in a parking lot. By reading every related post by mowton and Chris@HPTuners (Thank you Gentlemen), I was able to eliminate the return to Idle hang by reducing the low RPM Cracker air. I was able to slow the return to Idle with the Follower. Rolling Idle RPM set to 950. Rolling Airflow adder is .2 g/S across the board.
All is good until I depress the clutch. Then the RPM dips to ~600, or it just dies. I understand the TC and TF are disabled when clutch is engaged.
I noticed the the RAF table was zeroed in the P/N row. As a "shot in the dark" I populated that row with the airflow numbers that were in the In-Gear row.
and... VIOLA! Now when I depress the clutch, the RPM's drop to my Rolling Idle RPM and does not dip!!!
This leads me to a few questions...
Chris@HPTuners stated that the Rolling Idle "was a mode of the TC". Is the Rolling Idle and it's associated airflow adder also disabled with clutch in?
Is the RAF (P/N) used when the clutch is depressed until the RPM's drop to a point that Adaptive Idle takes over?
Does this tuning S/W consider P/N (Automatic) values the same as Clutch-in (Manual)?
Looking forward to any wisdom you gurus can share. Thanks for reading.
See my last post for fix.
