O2 simulators?

[gbs55]

I know there are O2 sensor simulators out there to be had. I’m interested in one that will do both O2 and heated catalytic ,4 wire simulation. Does anyone know where to buy these?

I know AA Tuning has them for their track pipes.

They have one of the best customer services around. Look up their phone number on the website and give them a call. They are awesome!
