If you're installing a Gen IV Chevy LS engine into a hot rod, street machine or any non-EFI vehicle and want to retain the LS engine's OEM electronic fuel injection system, the new Pro-Flo 4 LS ECU & Harness Kit w/o Tablet #357120 is what you'll need to complete the installation and get your Gen IV LS up and running to its full potential. This kit is designed specifically for the Gen IV LS engine with a 58X reluctor identified by the gray camshaft sensor mounted in the timing cover. The compact ECU and harness integrate seamlessly with the existing LS injectors, coils, camshaft/crank sensors and other factory intake manifold connections to greatly simplify the installation, start-up and performance tuning processes. This kit provides the perfect solution for those "junkyard" LS engine swaps where the factory ECU and wiring harness may be missing or damaged. The Gen IV LS ECU & Harness Kit #357120 can be used for any level of LS performance, and what makes this kit so unique and easy to use is the Edelbrock E-Tuner application, which eliminates the need for laptop tuning or costly dyno sessions. The E-Tuner is a user-friendly app that uses Bluetooth connectivity to communicate with the ECU can be downloaded free of charge in the Google Play Store to use with your Android-based tablet or smartphone. (Edelbrock ECU & Harness Kit #35712 includes a 7-inch Android tablet with E-Tuner app preinstalled.) The key to the E-Tuner's simplicity is a Setup Wizard that guides you step by step through the initial programming for your particular engine. Once you provide the Setup Wizard with basic data (type of engine, cubic inches, firing order, cam profile), the E-Tuner then selects the most appropriate base calibration for your engine. As you drive the vehicle, the self-learning E-Tuner continually maximizes the fuel map according to the environment and your driving style so that your engine is always performing at its best.

Edelbrock Pro-Flo 4 ECU & Harness Kit w/o Tablet #357120 is for use with Chevrolet Gen IV 58X LS engine installations into non-EFI vehicles. Allows you to retain the LS engine's OEM electronic fuel injection system.

Do you offer wholesale or jobber pricing?

Yes. Wholesale pricing is available for legitimate businesses that provide a valid business number or equivalent proof. Ongoing purchase volume is required to maintain discount eligibility. One-time personal buyers aren’t eligible.

Will this part fit my vehicle?

If a product page clearly lists fitment for your vehicle and the description leaves no reasonable doubt, we’ll cover the cost of return if it doesn’t fit. Exclusions apply if prior modifications cause the issue. When browsing self-serve, you’re responsible for confirming compatibility by checking manufacturer fitment data and notes. If unsure, contact us before ordering and we’ll verify it for you.

Do you offer technical support or installation advice?

We help where possible on a case-by-case basis. Most manufacturers include detailed instructions and tech support contacts. Because our catalog spans hundreds of brands, we can’t provide every torque spec or procedure, but we’ll connect you with the manufacturer if needed.

Do you offer price matching?

We don’t guarantee price matching, but we’re happy to review a legitimate in-stock offer from another Canadian retailer. The comparison must include all costs such as product price, shipping, taxes, and fees, and the item must be identical and available for immediate purchase. We won’t lose money to match unsustainable or out-of-stock pricing.

Can I exchange an item?

Yes. In-store exchanges happen on the spot when stock is available. For shipped orders, the original item must be returned first. Once received and inspected, we can issue a store credit toward the correct part or replacement. We can’t send a second item while the first is still in your possession without payment for both.

Are prices shown before or after tax?

All prices on the site are before tax. GST, HST, or PST is calculated at checkout based on your shipping address..
