Already posted on ecmlink forums, but figured I'd copy here as well:
So I finally fixed some pre-turbo exhaust leaks, and car seems to be running/boosting much better. A couple things I noticed... my boost seems to be pretty sporatic and falling bad on WOT. I plan on doing a BLT tomorrow to hopefully isolate my boosting problems. Could this be something else or def a boost leak?
On the first log I've got quite a bit of knock at low speeds (>20 mph). Should I be concerned with this and fix the timing tables?
Both logs I followed the fuel trim video, setting my openloop higher so I could get a decent MAFComp layout. The first log had some original tables, and the 2nd log has the first's logs suggestions and smoothed out. On both logs I have a few spikes (500hz and 1200hz), does the smoothing pattern look ok or should I adjust so it's not as drastic?
Another thing I noticed is my CombinedFT is still kinda all over the place +/-4%, even up to +/-8% at times... Should I adjust the deadtime at idle to combat this?
Lastly, on the first log I was able to get 2 really good pulls @ 169secs. My AFR from my LC1 is around 8, which is WAY to rich. I'm supposed to be at 10.5-11 on WOT correct? How do I go about fixing my AFR on WOT?
Sorry for all the questions, just wanna get my shit tuned perfectly
