Is there a way to relay the signal back from the cat sensor so the check engine light won't come on?

 

HUH?..your saying the cat is gone,and you have a ses light?..

Yes,there are aftermarket things to plug into the harness and fool the ecm.

Hope they don't do emission testing in your area.

 

My cat is not gone yet. I just want to take it off. I don't want the check engine light to come on. Some of my friends did it to their trucks and the check engine light came on. Where can i get something that would do the job?

 

I ran across this but not sure if it is what you are wanting. http://www.afterthoughtsauto.com/o2sim.html

You might try this website.

 

From what I have found, removing the cats will decrease mlage significntly, for only 1 or so HP gain. The new cats are very efficient, so leave them in, unless you are just using the truck for racing.

 

yeah they make little things you plug into your sensors that trick thecomputer for like 25 or 30 bucks...

 

not to mention its illegal as ****

 

You can also get a custom program done to get rid of the ses light. The reason the mileage goes to **** is b/c the ses light is on. If you get it programmed out, you'll be AOK.
