Ebay GT45 + 5.9 Magnum + E85 blow thru

Failure on the unit itself. The ECU failed apparently and had to be replaced at FiTech. Fortunately I was at home and not broken down on the side of the road. I got the unit back and am now working through a couple of other, less major, issues with it including a binding throttle linkage and a screen that goes grey on the handheld.
Good to hear, I definitely like your build and look forward to seeing your progress!
