Edelbrock Pro-Flo 4 Engine Management Systems for LS Engines Now Available

Edelbrock’s Pro-Flo 4 EFI Systems are a great way to add a tunable multi-port EFI system to bring your GM LS, Chevy, Ford, Mopar, or Pontiac V8 into the 21st century.

But you can save some money on your GM LS swap by keeping the factory intake manifold and EFI hardware and get the tuning advantages of the Pro-Flo 4 system with Edelbrock’s Pro-Flo 4 Engine Management System. It features the Pro-Flo’s self-learning ECU—just link it to Edelbrock’s free E-Tuner app and you can adjust air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, rev limiter, and other parameters using an Android-based smartphone or tablet. The E-Tuner comes with dyno-tested baseline calibrations and an easy to use setup wizard to get you started.

The Edelbrock Pro-Flo 4 Engine Management System is available with or without a tablet that has the E-Tuner app already installed. Summit Racing has versions for LS engines with 24X or 58X reluctor wheels. A wiring harness is included.
