Berk HFC passing emissions/CELs

JohnnyBgood · 08-13-2010, 02:37 PM

I had the Berks installed 15,000 ago. I did not put steel wool in the O2 sensors. No CEL's, and I love the sound and performance gain. (Also have the Stillen CBE installed.) It's my daily driver. I would highly recommend the mod.

Did you disconnect the battery before doing the install so that it resets the ECU? Just curious. When I installed my CAI they recommended that I disconnect the battery so I didn't throw a CEL.

It is not neccessary as the ECU will still adapt over a period of 5-10 drive cycles. Resetting the ECU after a mod will force the ECU to learn and adapt in a much shorter period of time. Instead of disconnecting the battery terminal, you can reset the ECU in car without touching the battery with this technique:

Read the process a few times before you try to do this its ALL ABOUT TIMING:

1) With the key in your pocket/car, push the Engine Start button TWICE (so the car is fully on, but not started)
2) Within three seconds of the car "ON" (again NOT started), Floor (all the way down) and Release the gas pedal fully 5 times within 5 seconds. Do not do this too fast.. 1..2..3..4..5
3) Wait 7 seconds then floor the gas pedal and hold for 10 seconds. After that 10 seconds the Check Engine Light will start to blink slowly.
4) Release the pedal and floor it down once again and hold for 10 seconds. After these 10 seconds the check engine light will disappear then begin to flash much more rapidly. After you have done the following turn the car off and then back on. The ECU is now reset!!

+1 for great information on the ECU!

Now could any of the guys who DID throw codes tell about their experiences? And if you did fix it, how?

If the code is for the o2 sensor reading too hot, that means you will have to have the o2 bung made longer which means going to an exhaust shop, having them remove the current bung and welding on a slightly longer bung.

However, I talked to Berk and all of their most recent HFCs have not had any CELS whatsoever because not only is the o2 bung much longer to pull the 02 sensor out of the exhaust stream, but the hole letting exhaust into the o2 bung is actually much smaller than the diameter of the bung itself.
