Keller Performance Tech Control Modules
Engineered to eliminate faults. Designed for full performance freedom.
Our advanced electronic modules are developed to allow seamless integration of aftermarket and race exhaust systems—without triggering check engine lights, hidden fault codes, or limp mode conditions. Each module is precision-engineered to maintain OEM system integrity while unlocking the full potential of your exhaust setup.
1. OPF (Gasoline Particulate Filter) Module
Purpose: Enables the use of aftermarket exhaust systems that retain or interact with OPF sensors.
Modern vehicles equipped with OPF sensors are highly sensitive to exhaust changes. When installing an aftermarket exhaust, these sensors often detect irregularities—triggering hidden fault codes, reduced engine performance, and limp mode activation.
Our Solution:
The Keller Performance OPF Module seamlessly integrates with the factory system, preventing sensor-related faults and maintaining full engine performance.
Key Benefits:
• Eliminates hidden OPF-related fault codes
• Prevents power reduction and limp mode activation
• Fully compatible with aftermarket exhaust systems utilizing OPF sensors
• Maintains factory drivability with enhanced exhaust setups
2. OBD2 Race Pipes ( Cell Free ) Module
Purpose: Required for vehicles running catless downpipes.
Removing catalytic converters significantly improves exhaust flow and performance—but will trigger a check engine light (CEL) and fault codes (commonly associated with catalytic efficiency, such as P040-related issues), often leading to restricted performance.
Our Solution:
The Keller Performance OBD2 Race Pipes Module eliminates these faults at the source, allowing uninterrupted performance with catless configurations.
Key Benefits:
• Removes check engine light caused by catless downpipes
• Eliminates fault codes related to missing catalytic converters
• Prevents limp mode conditions
• Plug-and-play integration with OBD2 system
• Ideal for race and off-road applications
3. Exhaust Flap Regulator Module
Purpose: Enables proper operation when removing factory exhaust valves.
OEM exhaust systems utilize electronically controlled valves (flaps). When these are removed or replaced with a valveless race exhaust, the factory system detects abnormal resistance—triggering fault codes and limp mode.
Our Solution:
The Keller Performance Flap Regulator Module simulates proper valve operation, ensuring the ECU reads normal parameters even with a full race exhaust system.
Key Benefits:
• Eliminates exhaust valve-related fault codes
• Prevents limp mode caused by missing valve actuators
• Allows seamless use of valveless race exhaust systems
• Ensures consistent ECU communication and stability
• Plug-and-play installation
Why Keller Performance Modules?
• OEM-level integration
• No check engine lights or hidden codes
• No power loss or limp mode activation
• Designed specifically for high-performance and exotic vehicles
• Trusted solution for race exhaust compatibility
