The Edelbrock (35893) Pro-Flo 4 XT Sequential EFI System for Chevrolet LS Gen III/IV engines makes doing an LS swap an even easier decision to make. With hardware that supports up to 675 horsepower and software which lets you tune your engine anywhere, Edelbrock has got your LS covered.

Features and Benefits:
- Sequential Fuel Injection system
- Capable of 550 horsepower
- Complete tuning control
- App based tuner connects to ECU wirelessly
- Waterproof, compact, and self-learning ECU

The black Pro Flo XT rectangle port intake manifold houses 35 Lb/Hr injectors which are capable of 550 HP with 58 psi of fuel pressure. An all-new compact and waterproof ECU measures half the depth of the previous version. The ECU houses a faster processor, and a faster Bluetooth chip that is more reliable and will not drop the connection. For plug and play convenience, the ECU is easily programmed with one of several dyno-proven base tunes, and is self-learning, offering no-fuss drivability out of the box. For the advanced tuner, this system can also give you complete control over air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, and rev limiter while retaining Pro-Flo simplicity.

The key to the system is Edelbrock’s exclusive E-Tuner 4 app. Your mobile device can also now talk directly to your LS’ ECU, offering on-the-go tuning possibilities. The E-Tuner 4 features an easy-to-use setup wizard to help you get started, as well as multiple dash displays for monitoring engine vitals and performance. Best of all, the system arrives with a QR code to download the free E-Tuner 4 app from the Google Play Store or Apple Store for IOS and android devices. With an XT style intake, high flow injectors and convenient tuning options, this Edelbrock (35893) EFI system will make engine management on your LS swapped project car a breeze.

Tech Tip: This kit will require a high-pressure EFI fuel delivery system. Fuel delivery systems are available and sold separately. This LS kit also requires a coil harness which is sold separately; your LS’ crank trigger will determine which harness you'll need. Gen III engines have the 24X reluctor design, while newer Gen IV engines have the 58X.
