If you are getting a CEL related to your HFCs it's probably the FI design that has the sensor plugging directly into the piping (unless they've changed their design). It will read too rich of an A/F mixture. It's been posted here that FI will sell you a solution - a non fouler - that sits the O2 sensor back out of the direct exhasut stream. Berks are designed and built this way but a few have sitll had CEL issues. I have had mine (Berk) for over a year with no issue.

Well aliiin ... ive had my HFC for about a month and have put about 1000 miles i wanna say and i got the CEL yesterday night..

I plug the cobb in and go to troubleshooting .. and it shows the codes ..

the BCM which is the TPMS and the catalytic code..

so im guessing thats it ..

i do have the FI HFC... dont they send you something that can fix the problem ?

soo ...

my car was dirty as FUkc .. and i turned it on .. ran to the store to get quick detailer and got back home and started washing it..

once i was done i took it around for a quick ride to get the water out..

all of a sudden my CEL goes off and it hasnt come back since..

WTF lol ..

and now the cobb reads no codes except for the BCM tpms sensors..

how weird is that ?

your ecm is probally not picking up a hard code so its not storing it. Usually if its a hard code it will turn on the light and will set a code in the ecu. Remember with the key cylcles on and off it will erase the code if its not a hard code. you need to space out the a/f sensor back so it will not read to much air flow.
