I ran my first datalog today, and it definitely needs tuned. I don't think any of the knock retard is actual knock. The MAF frequency and fuel trims don't seem to jive with that theory... not that I would know at this point! I didn't include them in this screenshot. I have been reading non-stop for the last couple days, and my primary suspects are torque management, burst knock, or just false knock from all the exhaust work done. The headers are not installed yet.

It's pretty hard to tell what's up without the actual tuning software so I can see what the stock tune is actually commanding. All I know is that it's pulling timing and that should be fixed. So far I'm loving this stuff. I think this is going to be a really interesting experience.

Tomorrow is install day finally. I took all the tools back to the shop that I was using to build a deck, knock out walls and install sliding doors, fix guttering, etc... the list goes on and on and on. My shop is whole again. Feels great.

I went ahead and shot a before video. I finally found a camera that records decent audio. This thing is going to be a monster when I'm done. Does anyone else's intake exhale like mine does when you shut the car off?

Oh man, I remember when mine sounded like that before the headers.
It is gonna blow your mind how loud it is when you put those on. I went with the 2 inch off-road connections and it can pretty much blow your ear drums if you are behind it.
To answer your question about the exhaust exhale, I'm pretty sure it is normal.
Have fun with the new headers!

I'm counting down the hours now. I need to remember to take my soldering iron, heat shrink, and wire with me or i wont be able to extend my O2 harnesses. That would be an install bummer.

Anyone know what gauge wire is used in the O2 harnesses?

Nevermind.

0.5mm = 24 gauge

To be honest man, you can make the O2's work without extensions or wiring yourself. I just cut the wrap a little and stretched it and it reached just fine. Just be gentle and careful not to pull anything out. Been just fine for like 6,000 miles. Be sure to get the rear O2's turned off by your tuner though.

That's just cutting corners and its not the right way of doing things. Either extend it yourself if you know how or buy the extensions instead of having wires pulled on and risk messing up your harness. I'll pass. Just my .2 though.

They are in. I forgot my camera, so I'll take a video tomorrow.

This car is stupid loud. Everything went great. We did headers on my car, and an oil change + tire rotation on my buddy's WRX. 3 hours total. The driver's side header barely touched the boot around the steering knuckle. Two of the rubber backs of the spark plug covers on the driver's side barely touch the two middle primaries. I'll get those carved out tomorrow so they're not touching anymore. They seem to be able to handle the heat just fine anyways.

I extended my own harnesses. I would buy the extensions next time. I have been designing/building electronics for 14+ years. I'm no slouch at soldering. The wiring they use in the harnesses doesn't take solder. It's something about the type of wire used. I wish I would have known that before cutting them. I have them temporarily spliced together and under heat shrink ATM. I'm gonna have to go back and hit them with solder bands when I get a chance.

I have an immediate CEL, but I also removed both rear O2 sensors. There are no bungs for them on TSP connection pipes. I do need to get my scanner out tomorrow and make sure the codes are what I expect them to be. I'm going to do a little datalogging tomorrow to see how everything is handling the new parts. Depending on how I feel the car is running, I might grab a quick tune from Jannetty to throw in while I figure out how to tune this myself. Hopefully I can open his tune up and learn a thing or two.

Good Tuesday!

I wouldn't have been comfortable with using the existing bundles. I added about 8".

Checked the codes real quick-like. Everything is as it should be.

0036
0056
0141
0161

All of them are rear O2 sensor heater codes.

Oh... and I had a feeling that was too thin of wire while I was at work, so I grabbed 20 gauge instead. That turned out to be a correct hunch. All of the wiring was 20 gauge. White/Blue/Black/Black for the fronts and White/Gray/Black/Black for the rears.

I flashed a tune from Jannetty at lunch today. The CEL took all of 3 drives to piss me off. We've got a little datalogging to do before it's finished, but the car seems to be running very strong. Warranty is officially dead.
