If you’re swapping an LS into your project, the Edelbrock (35730) Pro-Flo 4 XT Sequential EFI System for Chevrolet LS Gen III/IV engines offers convenience and modularity. With a host of tuning options, this kit will get your LS motor running how you want it to.

Features and Benefits:

- Complete tuning control
- App based tuner connects to ECU wirelessly
- Waterproof, compact, and self-learning ECU

The satin Pro Flo XT cathedral 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 connection. For plug and play convenience, the ECU 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. With dyno-proven base tunes, 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. The E-Tuner 4 app is free and can be downloaded from the Google Play Store or Apple app Store for IOS and andriod devices. With an XT style intake, high flow injectors and convenient tuning options, this Edelbrock (35730) EFI system will take your LS swapped project car to a whole other level.

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.
