ZHP NA Project - More Power

So as i said car showed 188 whp without the CAI K&N. After the dyno i installed the K&N CAI and a few days ago i installed the headers.
Unfortunately i had to modify the rear O2 sensor ports because it used to hit the wall. I cut the already crafted ports on the intake into half and wielded the halfs on the other sides. Unfortunately due to my lack of experience i didn't know that shortening the O2 rear sensor ports would mess with AFR. My AFR became lean, thus the DME provides more gas than it needs and doesn't run effectively. The rear O2 sensors clear so there is no chance of them hitting anything. They are not the lowest point plus the 90 degree adaptors i already ordered will change the direction. I was about to dyno the results but the lean code has postponed it until i install the adaptors.

















Here is the link to video of headers + k&N + Lean AFR problem acceleration

I have the OEM BMWP exhaust and is interested in buying the headers but

Will I have the cel light turned on?
Will it smell like gas in the cabin?

Why are you still using the secondary O2 sensors? You trying get the CEL to go off without coding out the secondaries?

Yes you will have CEL light. The secondary O2 sensors monitor the cats. No additional fumes are created with headers but the smell will completely different. If you're not used to it, then you may find it annoying.

any way to turn off the CEL light?? So will the cabin smell or no?

CEL: yes, you'll need a tune. AA has a tune that can do this, as well as delete the SAP if you want. more importantly (for us), they have a dealer in the GTA, so you don't have to send your DME out.

smell: i can't answer this directly, but from what i've heard... maybe.

personally, if i go with catless headers, i will be installing high-flow cats downstream anyway.

hmmmm....ebay item carted...should i check out...hmmmm lol

1. You will have the CEL light on you need to put the 90 degree O2 spacers to avoid.
2. No it will not

I am trying to get the CEL go off without coding out. I ordered the 90 degree O2 adaptors. In the future i am planning on coding out but after i will add the Bored TB and the Underdrive pullies.

has that worked for anyone?
