Frequently Asked Questions

What’s the difference between Gen IV 58X and earlier LS engine setups?

The main difference is the reluctor wheel signal. Gen IV engines use a 58X signal for more precise timing, while earlier engines use a 24X signal.

What is the 58X signal in LS Gen IV engines?

The 58X refers to the reluctor wheel signal used in 2007-2014 LS Gen IV engines. It allows for more accurate engine timing and is different from earlier 24X setups.

Is custom ECM tuning required for an LS swap?

Custom ECM tuning is highly recommended to optimize engine performance, especially in modified or swapped applications, ensuring proper fuel, timing, and throttle control.

Will the harness work with both drive-by-wire and drive-by-cable throttle setups?

These specific harnesses are designed for drive-by-wire throttle setups. For drive-by-cable applications, a different harness would be required.
