2023+ C8 Corvette Z06 LT6 LS9 3-Bar MAP Sensor Adapter Harness

This harness is designed for C8 Corvette Z06 LT6 applications that are being converted to forced induction, including twin-turbo setups. The factory configuration is not designed to accurately measure the higher manifold pressures seen under boost. Converting to an LS9 3-bar MAP sensor allows the OEM ECU to properly read positive manifold pressure and provides the accurate data needed for fueling, boost control, and calibration.

SOLD IN PAIRS

Our conversion harness provides a clean, plug-and-play solution for integrating an LS9-style 3-bar MAP sensor into the C8 Z06 LT6 engine harness without cutting or modifying the factory wiring.

Features

• Converts the factory MAP sensor connection for use with an LS9 3-bar MAP sensor

• Ideal for twin-turbo and other forced-induction LT6 builds

• Allows the OEM ECU to accurately read boost pressure

• Provides critical manifold pressure data for proper fueling and tuning

• Plug-and-play installation

• No cutting or splicing of the factory engine harness

• Developed specifically for boosted C8 Z06 applications

Why You Need a 3-Bar MAP Sensor

When adding twin turbos or other forced induction to the LT6 engine, accurate manifold pressure data becomes essential. The ECU relies on MAP sensor information to determine engine load and make the appropriate fueling and calibration adjustments.

An LS9 3-bar MAP sensor provides the additional pressure range required for boosted applications, allowing your tuner to properly calibrate the factory ECU throughout vacuum and positive boost pressure.

Many C8 Z06s reports "Reduced Engine Power" mode when tuning with the OEM LT6 MAP sensor. Best to replace it with a boost specific MAP sensor.

Recommended For

• C8 Z06 twin-turbo builds

• Boosted LT6 engines

• Custom forced-induction C8 Z06 applications

• OEM ECU tuning and calibration

• High-horsepower street and race builds

Note: ECU calibration is required when converting to a different MAP sensor. This product is intended for use with an LS9-style 3-bar MAP sensor and should be installed and calibrated by a qualified tuner.
