I just put a new RNR Carbon TI TBE on my car with a Helix HFC...I hooked up the O2 sensor and it threw a cell about the same time it took my test pipe to throw a cell...Is it because I have not tuned the car yet and its running to rich factory settings?...

Hi,

Did you get teh HFC from us? If so, please give us a call and we can send you a cell fix. The HFC normally don't throw a cel but it happens sometimes.

Thanks,
Tom

 

whats the point of running a "cel" fix on a high flow cat when you can run a "cel" fix on a test pipe

 

the helix threw the cel on mine too.

 

Helix tp with mechanical fix has never worked for me.

 

i did the perrin cel fix that way I wont ever have to worry about it again.

 

only time i ever get one is when i'm putting down to work slow, and haven't gotten on it, i'm used to it, i actually didn't throw a CEL on track with the test pipe and anti-fouler, was kinda funny

 

when i put my buschur turbo back on with the hfc, it threw a cell as well.

 

so i saw how the anitfouler is set up for this first time, but how does it actually work? lets in less exhaust gases?

 

Funny... I've never thrown a CEL with the spark plug anti fouler fix and my cat delete... that's been well over a year ago! You have to drill a precision hole for it to work right though. Can't just hog it out...

 

exactly

 

yeh i had to use the perrin cel fix on my 05 evo 8, this time i ll try the mechanical fix on my XI

 

i had the same problem with my helix HFC, since the mech O2 fix have not had a CEL in over a year

 

+1 And you have to wonder how well the HFC is doing its job if the ECU in the car thinks it's not.
