Next step is to introduce timing control. I've had a helluva time trying to get E85 to run good at idle and off-idle and just figured out the other day I'm not giving it enough timing at idle which was causing a huge bog/flooding condition when going off idle. I bumped up the timing to 18* at idle on my HEI ready-to-run distro and it's a whole new beast! Problem is, that puts me at close to 40* total timing when the mechanical advance kicks in. That will be way too much under boost. So, I'm looking at converting an old 2 wire distributor I had lying around to a locked advance, installing the old ballast and coil and trying to control the timing from the Fitech. We'll see how it goes.
