[Gmecm] DFCO and EGR elimination

[Dig]

A group of us  (don't know how many of them are reading here)  started a project to update/fix things we didn't like in $58. $59 was the most clever name we could come up with.

Bruce had started a similar project years back ($60), but it never really caught hold. This is different from his effort.

One of the features, as Bill brings up, is WB o2 control of non PE/AE/DE fueling. It works pretty good, thanks to Don's hard work, although it does require you to have a *fairly* close tune. (WB control loop kinda freaks, otherwise)

You may download/join for free at www.code59.org. The xdf files and other tools are there as well.

The only thing that we ask, per the license, is that if you use it, you must post your tune back to the board. The idea being, that somewhere along the line, someone will need something similar, and can use your tune as a starting point. It's intended to be free for all.

Last big disclaimer, since it seems to offend some:  The xdfs and code is set up for a 3 bar map. A number of people seem to have concerns about the driveability of the 3 bar sensor, but we don't have any problems with it in the field. To each their own.

Really last big disclaimer:  This is a work in progess. We haven't observed any major bugs, but that doesn't mean there aren't any.

Later,

Is $59 similar to $58?
