O2 Sensor Simulator
 

Preparing for new exhaust on my 01 S (headers eliminating front cat, CA DOT rear cats) & looking for alternatives to PIWIS found this: https://www.magnumtuning.com/en/detail/ez-cel-fix-oxygen-sensor-simulator

As an ancient software developer I'm leery of black market PIWIS due to possible malware & general inaccuracy although others swear by it. OTOH The hardware fix looks sketchy.

Whadya Think?

Running them now they work well. One day I’ll post a pic of what I tapped in the trunk, this form is just not ideal for uploading.

What specifically do you want to do?

If you want to eliminate the post cat sensors without the ROW tune, the easier way is to use these plugged into an unused boss
