Getting Closed Loop To Work?

Postby CMac89 » Sat Sep 01, 2012 6:46 am

I've been trying to figure out how to get closed loop to operate correctly. The idle and AFR changes between 16.x AFR and 14.x in a nice, smooth, oscillation. It idles steadily in warmup mode, though.

Is this a common thing? If so, what do you guys recommend I do to fix it? It would be great to have it working correctly.

Before trying CL idle or CL EGO, you need to be sure that your idle is quite stable at a constant PWM idle duty and the VE at idle shouldn't vary. Post a datalog and your msq file.
