Gen3 Idle Control with low vacuum
I am working on a 2019 Gen3 with a large cam, VCT lockout, and more. My question pertains to my ignorance of how the idle control systems REALLY work on the platform. This car in particular has much lower vacuum than a factory engine. It holds about -6 psi at 850RPM, which makes the car idle at a much higher "load" point in the torque reserve table. I've been struggling with this for quite some time, by "bending" the torque reserve at certain load points (.2 - .35) I can "force it" but it causes other problems in the torque calculations once it's off idle.
Is there a way to "offset" the torque idle? It appears that the idle torque reserve table may be what I want. Is there a good explanation of how this or other tables work or a flowchart on how the idle circuit functions on the platform with the available tables?
Thank you all for your time!
