No-hassle Hemi Swap with Holley Self-Learning EFI

Self-adjusting programming no matter how your Hemi is built

The Gen III Hemi engine holds a lot of potential, but ease of swapping into non-factory applications has never been a strong suite. Holley has made it much easier to put a stock or modified Gen III Hemi in your project with its self-learning Holley EFI system for these engines. The system includes a plug and play wiring harness, self-learning computer, and controls for ignition, fuel, and the drive-by-wire throttle. Just plug the system into your stock or modded Hemi and let the Holley System do the rest.
