you would have to find out the specific laws for NC. look on the DMV website or call. google it.

 

i know the nc laws because i am a licensed inspector. will a tune tell the obd emissions computer that i have cats when i really dont?

I don't know about NC but in pa my catless setup passed the ODBII test.

 

You want a 'Pony Express' CEL fix. Simply a resistor that sends the signal the OBDII wants to hear. I am catless and have not thrown a CEL since the 'test pipe' went on and the PEP was placed inline (between O2 sensor and the OEM ECM).

Here in Oregon they don't 'sniff' the exhaust ~ simply plug into the OBDII ports and look for a CEL history or 'check engine' light...

 

thanks NW OBS. thats what i was trying to figure out. when i go catless i wont need a tune will i?

 

I can reflash an ECU to make it NOT throw a CEL for the cats. However, it's really really hard to fool it into giving you a readiness code for the catalyst. It IS possible. You have to change the voltage range in the ecu. Depending on the year, make and model, I may have everything right here in my house for that. Adding a spark plug non fouler to the 02 sensor and changing the voltage range works every time.

I'm in VA btw.
