TECHNICAL INFORMATION
The original airflow meter is made redundant when configured for the aftermarket ECU. If the AFM is removed, an alternative intake air temperature sensor is required. A suitable MAP input and wideband oxygen sensing arrangement must be selected to suit the ECU and engine configuration. Additional wiring from the spares connector can be used for boost control applications.
IMPORTANT INFORMATION
Haltech ECU is not included.
Factory immobiliser functionality through the original ECU is not retained.
Original oxygen sensors are not used in the specified Haltech wideband configuration; additional wideband hardware is required. Nexus ECU options may use their integrated wideband capability with compatible sensor hardware.
Final compatibility and supported functions depend on the selected ECU, model year and transmission.
ECU setup and dyno tuning by a competent engine tuner are required. Any provided base map is a starting point only.
