The Daytona Twin Tec FI to Carburetor Conversion Kit moves a '01-'11 Delphi EFI Twin Cam back to a carbureted fuel system using the existing wiring harness. There are good reasons to go backward. Carburetors are simpler to diagnose on the side of the road, cheaper to rebuild, and easier to tune without a laptop. Daytona Twin Tec built this kit so that swap does not turn into a wiring project, and so the turn signal and security module keeps working exactly as it did before. How the Conversion Kit Works The kit converts a Delphi EFI system to carburetor while retaining every function of the turn signal and security module, which is the part most improvised conversions get wrong. It uses the existing wiring harness with no modifications. Required software and detailed instructions are included. Made in the USA.
