JB4 O2 Simulation Question

Ok, so I live in GA which is an emission controlled state and have a JB4 I'm about to install. I read that on map 0, OBD2 works. If I am on map 0, does O2 simulation still work?

This will determine if I go with a catless downpipe.

I am in GA too. I just run the BMS downpipe fix and my car throws/shows no codes on cattless DPs.

Set the car to map 0 and go to emisions. If your catless then you need DP fix. If you have cats then you dont need the DP fix.

That's what I needed to know. Thanks!

I thought the DP fix just stops the check engine light? I thought you would still fail emissions?

I don't know, just what I understood. Could be wrong

The built in feature on the JB4 will NOT pass emissions...it constantly gets a "not ready" status.
The external DPfix actually simulates a working o2 sensor and will allow a "ready" status needed in order to pass.

NJ only plugs into OBDII and does not actually do the sniff test so GA may be different but the DPfix works like a charm in NJ.

Here in GA they just plug in... So sounds like just get the DP fix and be good to go.

Same here, just plug it in. Technically, if they look under the car I guess they could fail you, but they never do.

When they look under the car; the secondary cats are still there so no issues.

Grab the BMS if you are going catless. They have great price and fitment. From same place as your JB4 and DP fix.

I put them on myself. Not too bad.

ANd yea no way to get under my car either. Its only about 3 inches off the ground. The emissions place will just plug into OBD2 port here in GA.
