Tuning Help K20Z3

Post by MYNAMEISJEFF482 »

I'm looking for some tunning help on my K20Z3,
I recently got my 06 Honda Civic SI I'm unsure what has all been done to it before me, but I know for sure it has Skunk2 Headers and a custom exhaust with unknown origins it throws cat codes so we are guessing no cats and it has a muffler that also has unknown origins.

When I got my FlashPro I put a burble tune on it made by me. It was something that I felt comfortable with and its something I like, but that's about all I know how to do so I'm looking for assistance.

I have one good data log of me cruising for a little bit with no hard throttle, but I will have more included tomorrow when I go out. I have other data logs but at the time my knock sensor went out and because of that I am not comfortable with sending those. I have since then replaced my knock sensor.

You need to adjust the MAF. The car is running rich to the point its maxing the trims.
