[Gmecm] Closed loop

[David Haggard]

Thanks, Steve.
 
And by the way, regarding the first half of my questions--
With more digging and searching I found an article on '747 fueling logic Lo and behold! There is a set of O2 sensor "window" settings that _MIGHT_ control how much and how fast the ECM makes fuel corrections in closed loop. One setting in particular is said to help smooth out the idle of a "rumpty-rump" engine. Notice, I emphasize "might." We shall see.
 
I'll try it, and let the list know how it works.

David
I don't think I have ever seen a hiway mode ever documented for the 747 anywhere (unlike many others) but "I could be wrong" 
 

Bob Rauscher wrote a highway cruise patch for the 747.  It's on the FTP site, look for something like 747hwy.zip.  It might be linked from the gmecm page under projects also.
