[QUOTE="decipha, post: 16757306, member: 74327"] stangra, the 11-17 coyotes have a "mechanical returnless" fuel system. It functions exactly the same as a return style system its only called returnless because they mount the fuel pressure regulator in the tank so the return line is inside the tank. There is no fuel pressure sensor thus the ecu has no control of fuel pressure thus it cannot modulate fuel pump voltage like in an actual returnless setup. Before the coyotes existed I used to do the same thing on the older foxbodies so I wouldnt have the run a return line all the way from the front. But yeah you simply write a stock roush e85 cal to it. Before you say there isnt one its just that you arent aware of it. Just like a stock 03/04 cobra automatic tune... just because it wasnt a production cal doesnt mean it doesnt exist. Shoot me an email and we can discuss what all needs to happen and pricing and all that. I need all the specifics. [/QUOTE]
