Capristo Lambda Simulator for the Lamborghini SVJ

The Capristo Lambda Simulator is a high-performance engine management accessory designed specifically for the Lamborghini Aventador (including LP700, LP740, LP750 SV and SVJ variants) that have had their catalytic converters removed or replaced with racing components.

• Purpose: A programmable oxygen sensor (Lambda) simulator that maintains correct Lambda (oxygen) value signals to the Aventador’s engine control unit after the catalytic converters have been removed.

• Function: Delivers accurate simulated sensor readings to the ECU to prevent Check Engine Lights (CEL) and unintended limp or emergency modes that occur when the factory sensors detect out-of-range exhaust gas values.

• Compatibility: Works with Aventador models where catalytic converters have been removed or replaced with performance exhaust systems or test pipes (commonly fitted in motorsport or dedicated track builds).

• Installation: Typically installed inline with the aftermarket exhaust system’s oxygen sensor harness; requires programming to match the specific exhaust setup to ensure stable sensor feedback.
