I don't see this topic discussed a lot, and often times question raised regarding Kpro passing the emissions testing, the generic answer is "Yes it will pass testing".

Having my tags due next month I started to get a little worried because I just can't find any exact info regarding what to expect at DEQ so I thought I'd share my first hand experience with everyone on what to expect when taking your car in for testing.

First, before I even went to DEQ, I made sure a few things that will work towards my advantage.

- Plug in K-Manager and double check and make sure the VIN is actually entered in your Kpro! My tuner actually forgot to do this on the initial tuning. Not only verify that its there, but make sure the VIN match up character for character.

- Pick a date and time that you know that DEQ is swamped. Not knowing exactly what will happen when DEQ plug in to the ODB2 port, I was worry something might go wrong. This actually saved me.

So with that, I decided to go on 9/30, the last day of the month, and sure enough, my local DEQ was packed. Even with all 8 bays open, the cars were still parked around the block into the streets. It literally took about 1hr for me to get tested.

Here is the fun part. Upon the initial plug-in of the ODB2 scanner, the DEQ system threw an immediate error. The lady tried again, and it error out again. So now she's calling her supervisor, and I began to panic.

The supervisor showed up, and said something about needing an override. So he mentioned something about the computer is telling them that the readings do not match to the data in their system from 2 years ago from my previous test. (I just upgraded to Kpro this summer)

So not knowing what they will do at that point, I quickly mentioned that I had recently upgrade some of my engine sensors to the more updated OEM honda sensors which they are using for their latest model S2000's because I needed them to be replaced. (this was pretty much true anyway).

From that statement, the DEQ supervisor seem to accepted the difference in DEQ read out, and decided to to completely override the system error message and tested my car with a hand-held system, and then proceeded to pass me since I was holding up my line, and people were getting upset.

So the conclusion is that even with Kpro, its not as easy as one might think in terms off passing emissions testing with their current system. But with some luck, it should still pass no problem. But just make sure you actually have the correct VIN number entered in Kpro and don't go on their 'slow' day so they start calling dealers to verify what's in your car. I'm also not sure if I have to go through all that again in 2 years, or if the DEQ system is now updated with my Kpro readings.

 

God bless FL.

Out of curiousity...did they say exactly what was different? I'm curious to what readouts they're looking for.

 

No they didn't really say. Just the data output not matching to data from previous testing.

 

Yea passing emissions is the worst thing about owning a turboed s2k. I allways reset my ecu, reinstall my cat drive 90 miles to reset the freze frame data and hope the tester dosent look under the car. (I have open wastegate, which would automaticly fail me if he saw it.)

Does Kpro have full obd2 functionality with all of the s2k's sensors? Thats the only reason I like to run a piggyback ecu,(emu) because I can retain all of my obd2 functionality and still pass the obd2 plug up test during emissions.

 

Yes it does retain all the OBD2 functionality, and more. (I belief you could 'override' certain readings to a value you want to output through the OBD2).

 

The big problem is I'm pretty sure the k-pro shows the car as an Acura RSX regardless of the vin# instead of honda s2000. Should have told them the Ecu got damaged (flood, water leak etc) and had to be replaced

 

IN Colorado i had no issues with the OBD2 stuff....

the emissions place plugged it in and it worked seamlessly with their system i also had my car tested at the same place two years prior...

 

Ive heard of several states (mine included) failing kpro equipped s2ks . That sucks ! They just dont like the fact that the ecu says it belongs in an rsx .

 

Just moved to Portland area and have a turbo S2000 with AEM ECU. Considering doing the swap to Hondata K-pro if that's what it takes to pass here. Any tips & ideas welcomed.

 

In texas, as long as they can plug in, get a response from ecu, and no CELs, you pass. Their system doesnt even check for type of vehicle.
