$OD Lean Cruise
From what I understand lean cruise works with the EGR coding,
Is it possaible to run the code with out the EGR valve in place
and still make lean cruise work?
How does it know when the valve is open or closed or even there?
Please fill me in on what makes lean cruise tick.

Re: $OD Lean Cruise
The EGR is not necessary for lean cruise although I recomeend it to be. $0D lean cruise simply returns the PCM to a semi open loop state, in that the PCM will adjust the long term fuel trims, but command the air/fuel ratio from the a/f ratio vs. coolant vs vac table.
