They also ran the engine o= n the new Swift 94 fuel, and while just operating the same 550 in the = standard turbo normalized mode, the engine analyzer displays show= ed alot of detonation taking place, which could be a reason the Univ. of No= rth Dakota blew up a couple engines on their training birds, after swi= tching over to that fuel
