Actually I was thinking of getting on the presidential GOP ticket in a couple of elections from now. With my brains or lack of, and my good looks I will be a shoe in. Not to mention the fact that I love groping men women and boys more than a Penn state bench couch.
So I fucked with the dwell tonight after I got home and guess what? Problem is looking to be getting better. I shaved some just ever to slightly at 6800 rpm, and what do you know. The car pulls almost like it used to. Thanks for all the help guys, I think. I am working on some really classy frontal shots by the way for you faeflora. Hope you like ungroomed bush.

This thread is getting like this:

I like this OP though, he's a good sport. Seems like another prestigeous member of MT.net society!

I appreciate it thirdgen. These guys are nothing compared to the Subaru boys. Plus I have a weakness in my heart for guys that act gay to cover up the fact well that they are gay. Sometimes that closet is really hard to find your way out of.

So I'm going to build some detcans in the next day or so and keep reading more threads. Again I wish that the hydra manual explained things just a touch better. That way I wouldn't have to keep asking questions, and having to explain to my wife why I keep locking myself in the guest bedroom with the camera.

If the hydra does start to see knock and pulls timing will it be fairly evedent from the data log?

I would think you'd see the timing change in the log...so, "yes".

None of that. I just want a pic of you full frontal. You can put a piece of paper with "dwood11" over your face and pee pee if you'd like. If you want to show your face, please look sad.

Good job. Dwell can be a real ******* bitch to tune. Sometimes.

If you have the hydra log KNOCK RETARD then yes, you will see the amount of *s the hydra pulls in the KNOCK RETARD column. Always log knock retard.

So what's the worst thing that can happen if I take too much dwell out?

Word. So what's your best guess why after the addition of the can that it started to stumble and taking some dwell out helped it?

Reread thread. I already said because your boost took a ****. Who knows, maybe backpressure caused combustion chamber shittiness and spark said **** you?

Ok now I got another question for you. I turned the boost up and lowered the dwell a touch more, as well as shave more fuel. Now Im holding around 12 psi, but my afr's went back down. Is it because of less spark? Check out my last pull I just got done with. Its 4th gear by the way.

You 02 sensor is looking for Oxygen in the exhaust. You will have excess oxygen (AFR high/lean) two ways:

1. You are actually lean.
2. You are misfiring and the Oxygen is not consumed.

So, if you were misfiring and that misfiring stops, you should expect AFR to drop to the real value.

You still owe Fae that pix.
