Are you talking about the ZPI o2 sim? Well from what I know this is a device that is spliced into some of the ECU wires and basically eliminates the CEL light that comes on when you put on a aftermarket header on. It should work for all the headers out there currently. It's suppose to give you the correct AFR because its not actually tricking the o2 on the s-pipe but actually reprogramming it for proper readings. ZPI claims that it fixes your MPG but people with the antifouler mod don't seem to have a problem with MPG.
From reading about the antifouler mod it seems to work for some and not work for others. This could be the result from damaging the o2 sensor or improper installation. I'm not sure how you can mess up installing one of these but there is a lot of new people moding thier cars for the first time.
