Science of speed stage 2 supercharger - NC Emissions
 

I currently have the stage1 sos supercharger, and love it. I am debating upgrading to the stage2 but I think emissions would be a dealbreaker. Anyone know if stage2 can pass or what my options are. Thanks!

If you are 00-05, you'll have a bit more work ahead of you. 06-09 can use Hondata FlashPro for tuning and still maintain OBDII functionality for NC emissions checks. If you are 00-05 and wanted to invest the money in Hondata K-Pro, then it basically would be the same as the 06-09's and you'd be good on OBDII functionality. Otherwise, most if not all of the other tuning options for 00-05 will lose your OBDII function. AEM V1/V2 (and Inifnity from what I understand), Haltech Platinum Pro, etc. lose OBDII functionality, so the NC inspectors can't inspect the car. That was my situation when I went stage 2.

My solution was fairly simple. I had the Haltech Platinum Pro ECU, no good for NC inspection. So a few days before I needed to get my car inspected, I put in about 1-2 hours of work into my car.
- Removed the Haltech ECU and plugged back in my OEM ECU
- Removed my ID1000 injectors and replaced with my OEM injectors
- Removed my SOS MAP sensor and replaced with my OEM MAP sensor
- Removed my test pipe and replaced with my OEM cat
- Removed the drive belt off the back of the supercharger pulley

If it weren't for the test pipe/cat switch, everything else would have only taken me an hour or less. Not much work at all. Getting the car on jack stands and swapping the cat took longer than everything else combined. Then just drive the car for 2-3 days to clear all the readiness code checks in the ECU, and go get inspected.

When you've passed inspection, its 1-2 hours of work to get everything swapped back, and you're good for another year. Maximum four hours of work for a year's worth of "legality". Not a bad trade-off for 400+ WHP.

I did the K-PRO upgrade. It's passed NC emissions for years now. No worries at all. Just a bit of work as CoolGuy said......it's a bit of work.

To clarify - if I have an 06 and Flashpro would I still need to swap injectors, map sensor, tune etc. to pass inspection or will OBDII and a HF cat let me pass inspection in NC as is?
