Hi guys,
I'm running into an issue with my idle tuning. This is on a 2000 Chev Silverado 1500 5.3L with P01 ECU, has a turbo and a moderate cam. I'm running the Enhanced 3 Bar OS if it matters.
I can get the truck to idle fine in Park, Reverse and Neutral. When I put it into drive though, the ECU pulls a bunch of timing causing the truck to idle rough and drop a bunch of RPM. To compensate the Desired Idle Airflow ramps up to its max to try and bring the RPM back up.
I have figured out that it is the torque management that is causing the ECU to pull the timing. If I zero out the torque management table, the truck idles fine in drive, but I'm concerned that it will damage the transmission since the torque management won't be pulling any timing during the shifts.
Is there a way I can disable torque management at idle but still have it active during shifts?
I've made a video to illustrate the problem here: https://youtu.be/mtFgbxQXFug
Let me know if there's a way around this.
Thanks
Randy
