High Idle Condition Log

[RevGTO]

Hey All,

i'm seeking someone to check out this log file and give me any thoughts you may have about what could be happening? The backstory is in this thread: https://ls1tech.com/forums/pcm-diagn...e-control.html

in the log I'm cruising at about 40mph @ 1600 or so rpm with my foot off the throttle. As approach a stop, i shift into neutral to be able to slow down, (at about frame 25) and the rpms spike to about 2600, all with my foot off the throttle. As the car comes to rest, the idle slowly settles down to about 900 (setting is at 650).

This intermittent problem is continuing to vex me, and maybe someone who is a more expert tuner can see something in the log I don't see.

Check out B4309 and B4310, as well as B4332

Check out B4309 and B4310, as well as B4332All those PIDs are stock in the tune. As far as the log goes, the TC airflow is around .30lbs/min when the car is manifesting the "cruise control" effect at 0 throttle and about 1600 rpm. As soon as i shift into neutral and the rpms start to climb, it rapidly descends to zero.

The TF airflow is zero across the board.
