kind of hard to deal with. Adding the Zeitronix gage gives you an analog variable 0-5v output. A/F like you say should be pretty easy with this, but you really want to adjust timing at high torque and loads. Adding timing back under these conditions is a really big advantage of running E-85. Then you want to adjust boost, which I think you can do with an AEM engine management system. There are guys on the EVO forum that have been talking about doing this for seems like about two years. Just found it, two years.
