Im looking to build and sell O2 simulators but how many guys are in need of them. they would be for a 4 wire sensor downstream( thats what ive tested so far) They have worked for me on my 97 f150 v6 with high flow cats. let me know if there is a demand.

 

How much $ are we talking?
I would be interested 2007 f150 4.6L

 

Nah, you don't need them with HF cats on these trucks. You need them when running NO cats.

You making these ? -

 

Yes, thats what i would and have made are the MIL elimators. im looking for about $20 for one or 35 for 2. they would come with everything to install also, heat shrink, connectors.

 

is it the black or gray wire thats the signal wire?

 

These were very popular up to a few years ago with many of the high performance car groups and crowds. Then about 2-3 years ago a law came through that completely outlawed them from being made and sold. You may still find some companies out there selling them, but it's only a matter of time before they get caught too.

Any decent tuner can just tune out the rear O2's anyway. The front O2's don't look for the cats, only the rears do. Any tuner that's worth a crap can delete them and you won't have to worry about it either way.

Mine are tuned out and removed with no issues and no CEL's at all.

To the OP, best of luck to you in making them, but be aware of the risk you are taking by making and selling them. Just a little info for you.
