Enabling Lean cruise in the '746 ecm
Im running the bin AXKW in tunerpro, mask is 61v2. Wondering if lean cruise needs to be enabled or if its already on? If it needs to be enabled, how do i go about turning it on? I thought there was a flag for open loop afr but i don't see anything like that.

Re: Enabling Lean cruise in the '746 ecm
The qualifiers for lean cruise are scattered about. And, some of them have a dual purpose. The easiest way to see if the ECM goes into lean cruise mode is with a WB. If the AFR increases into the 15 - 16 to 1 range, then it is in lean cruise.
Note that the qualifiers look at CCP DC%, EGR, CTS, VAC, MPH, MAP errors, and closed loop active.
