Frequently asked questions
What does it do?
The SAP Simulator allows removal of the secondary air pump without triggering the check engine light.
Why would I want to remove my secondary air pump?
Most aftermarket headers have no provision for the secondary air pump tubes.
Is it difficult to install?
Installation should be easy for most people familiar with working on their car. Once the secondary air pump is removed, the SAP Simulator mounts with a single screw and plugs into the OEM connectors: the SAP power connector and the pre-cat oxygen sensor connectors under the fuel rail cover. Nothing to cut or splice.
Is it emissions legal to remove my secondary air pump?
No. The SAP Simulator is for off-road use only, not intended for highway vehicles.
BMW E36 M3 post-cat O2 simulator
Eliminates the check engine light when you run without cats (track pipe or custom exhaust). It simulates the stock O2 heaters and signal, and one black box covers both post-cat sensors, so you need just one per car.
