Passing State Inspection w/ JB4

[Wafernut]

I am currently running e30 mix ethanol. I need to pass inspection which always hangs up on the o2 sensors. Can I return my tune back to stock and be able to pass? Or should I run all the E30 mix out, then set my tune back to stock?

Also, is there a certain amount of miles you have to drive before the 02 sensors read, if any?

Thanks for everyone's help.

The JB4 doesn't change anything with the ECU. Remove it, go get inspection, put it back on if you're concerned. What's in the gas tank won't matter.

You won’t pass inspection with the JB4 installed.

You won’t pass inspection with the JB4 installed.

Not sure if this is state specific (Probably CA?) but I had no issues getting inspected with my JB4 on in TX

If your state allows vehicle modifications, you’re fine.

Depends on the state.
As said, TX doesn't care as long as the ECU passes the self tests.
CA it's illegal to even purchase.

Also depends on the inspection shop and how you pay them. I know a guy that has some junk that's nearly at the TX antique level (no emissions check after 25 years) - but not quite. The thing is a pile, probably has a broken ring, maybe a blown head gasket, but he keeps driving it. It passes as long as there's a 6 pack in the passenger seat when he goes to the Special Mechanic for inspection.

So I currently have a JB4 on my 2018 Kia Stinger GT and I am wanting to get Catless down pipes but I will have a check engine light do to a CO2 sensor and my car won’t pass in the Texas inspection so is there anyway through the JB4 I will be able to delete the CO2 sensor code so I’m able to pass my inspection?
