OBD2 Plug-In Check Engine Light Solution for Header Upgrades

The Yonristic Lamborghini Revuelto Header CEL Eliminator Module is designed for owners upgrading to high-flow or free-flow headers who want to avoid header and O2 sensor-related check engine lights. Simply plug the module into the factory OBD2 port, and it communicates with the vehicle to eliminate exhaust header-related warnings, helping prevent limp mode while allowing the Revuelto to perform at its full potential.

The Lamborghini Revuelto is one of the most advanced V12 hybrid supercars ever built, and its ECU closely monitors the exhaust system through multiple sensor channels. When upgrading to aftermarket headers, whether using 200-cell high-flow catted headers or free-flow catless headers, the factory system may detect changes in exhaust flow, catalyst behavior, or O2 sensor readings. This can trigger a check engine light and, in some cases, cause the vehicle to enter limp mode.

The Yonristic Header CEL Eliminator Module is engineered specifically to solve this issue. It is a true OBD2 plug-in solution, designed to connect directly to the vehicle’s OBD2 port with no wiring, cutting, splicing, or ECU flashing required. Once connected, the module helps eliminate check engine lights related to header and O2 sensor changes, allowing the vehicle to operate properly with upgraded exhaust hardware.

This module is compatible with both high-flow catted headers and free-flow catless headers, making it the ideal solution for Revuelto owners seeking maximum exhaust flow, stronger performance, and a more aggressive F1 sound without constantly dealing with warning lights. By preventing header-related CEL and limp mode issues, the system allows drivers to fully enjoy the benefits of their exhaust upgrade.

A key feature of this module is its built-in signal indicator. The module is designed to help identify whether the check engine light is related only to the exhaust header / O2 sensor system or if the vehicle has another unrelated fault. This gives owners added confidence because the module does not simply hide every issue blindly. If the warning is related to the header upgrade, the system handles it. If the car has another issue, the indicator helps make that clear.

This is the perfect companion product for Yonristic Revuelto F1 Race Headers, but it can also be used with other aftermarket header setups where O2 sensor or catalyst-related warnings occur.

Key Features

OBD2 Plug-In Installation

Simply plugs into the factory OBD2 port. No coding, no wiring, no cutting, and no permanent modification required.

Eliminates Header & O2 Sensor-Related CEL

Designed to eliminate check engine lights caused by high-flow or free-flow header upgrades, including O2 sensor and catalyst efficiency-related warnings.

Helps Prevent Limp Mode

By addressing exhaust header-related fault signals, the module helps prevent the vehicle from entering limp mode after header installation.

Works With Both Header Options

Compatible with 200-cell high-flow catted headers and free-flow catless headers, giving customers flexibility based on their build.

Built-In Signal Indicator

The module includes an indicator function that helps show whether the check engine light is caused by the exhaust header / O2 sensor system or another unrelated vehicle issue.

Important Notice

This module is designed specifically for header and O2 sensor-related check engine lights. It does not eliminate valve actuator-related faults.

If you are installing an aftermarket exhaust system that does not use the factory exhaust valves, or if your system uses remote valves or no valves, you may also need the Yonristic Revuelto Exhaust Valve Simulator / Valve Eliminator.

The Header CEL Eliminator Module and the Valve Simulator are two separate products because the Revuelto monitors the headers / O2 sensors and exhaust valves through separate systems.

For a full aftermarket exhaust setup with headers and non-factory valve operation, we recommend using both modules together.
