Okay, I think this is the right forum...
I've recently decided I'm finally going to get my car running better. I've never really had a chance to tune as every time I got stuff "right" something else would go wrong.
My combo is in the sig and is current/accurate. I currently have the Alky gain set at 4.
I noticed before that I was way rich (9.5 to 9.7\ish at WOT) on the Wideband so I removed WOT fuel from the chip, I think -14.8%. That got my O2s into more reasonable territory, still really rich just not as rich, into the low to mid tens.
While I was doing all this I’m noticing a small bit of KNR. I usually go out and wait for traffic to clear and do a quick pull or two if I have time. I’m noticing a pattern. Typically the first run has ZERO KNR. Then the KNR shows up in the second and third pulls. When it does happen, it is only a degree or so, usually starting with a spike around 1.5 degrees then tapers off to nothing in about 18 frames or so. Sometimes it does the same thing about 10 frames later. These are all in third gear and near the end of my runs where I’m close (but not yet) to letting off cause I’m going too fast for the street. My logs say around 75 MPH is where it starts but my speedo is off a little and 75 MPH is more like 64 MPH. I’m letting out around 95 MPH indicated which is more like 80.
My chip is burned for 22 pounds of boost, I’m only at 19 on my gauge and I’m RICH even having removed fuel. I don’t want to hurt anything and I hear nor feel any knock or I would have let out of it. How am I getting KNR? Is it possibly rich knock from still being at 10.2 AFR when the last KNR occurred?
I really appreciate any help you can offer a long time owner, but new tuner =)
