[SEAT TIME RULES]

I'm wondering if anyone has tried these on their S55 motors?

I've got the HFC Wagners on my car and I've tried spacers etc and I still can't get my O2 sensors in "ready" state to pass Inspection.

I know that they work on several other BMW engines, but I'm not sure if they ever came out with ones that do work on our cars.

Anyone???

Well I heard back form Area 74. No go...

So what's everyone doing with their S55 O2 sensors?

There are many on the forums running HFC's, or straight downpipes...

Have you tried some spark plug non- foulers ?

I've got a pair of 45 degree angles mini cat O2 spacers from Racing Dynamics on it now. Great units and they did get rid of the P420 codes, but they aren't warming up enough to get the sensors in "ready state".

Well I finally found the proper combo to pass MA inspection.

I have a AK Motion Unit which I turned off.

I also installed the racing Dynamics 45 degree Spacers with Mini Cats.

Then I put the stock tune back on the car and made sure the O2 sensors were set for "OEM".

Last and most importantly I drove the car the 25 or so miles to get it reset and ready for the Inspection.

What ended up being the last piece of the puzzle was not running the car in "Sport, or Sport Plus" during the reset process. When I did have it in one of those settings I would throw the 2272 code. (Code P2272 is a code indicating the O2 sensor post catalyst on bank 2 is staying lean all the time. )

I ran it the default setting and drove the car with very little throttle for the 25 miles.

BINGO! I'm legal again.
