LSX Closed loop idle

Post by LSXCutty »

I know I have this pretty messed up. I have been playing with this and now when I'm sitting still and tap the throttle a slight bit the rpm increases a bit but takes a little while for it to come back down. Also when driving down the road the stepper will fully close and if I get on the brakes enough to a complete stop it will almost want to stall until the stepper starts opening. They attached datalog is the sitting still and a slight rev.

I see a few things you can change that may help.

Under Idle Control set Power Between Steps to always on.

Under Closed-Loop Idle Settings set Idle Valve Minimum Steps to 40, also set Max Decel Load (%) to 40.

I would also turn off Idle Advance for now, it is not set correctly.
