My old mini afc died a couple nights ago. Im limping along with my lq4 maf sensor plugged in directly and flashing the table back but I don't dare go above 5k rpm. Im hitting 11250hz at 5k rpm so I really don't have an option other then to get a new afc.

The question is should I go with a standard programmable mini afc like I had before or should I go with the newer afc gauge? Since I run e85 it would be pretty handy to be able to adjust for different blends by just turning a nob (Or run gas in an emergency) but im wondering what you guys think about it? I feel like it would be more reliable as well being in the cabin but im worried someone could bump the nob by accident? Or is it pretty hard to change by accident?
