Finally got my engine to run without throwing a code or having 20 degrees of knock retard. Which was my problem all along since the ecm swap. Now I can actually get into the tuning portion properly. Next mod: Exhaust.

That's great man.
Was it just the incorrect knock sensor that I read in the PROM thread causing you the problems?
Are you going to give it another go on 9/20?

It was actually the external knock filter that maf uses, while the SD unit has it internal, so the knock single was passing through two 'filters'. Funny that in my research for the swap I never ran across that portion of it. All I had to do was unplug the two wires from the external filter and mate them together. I was curious as to why when I backtracked my rewiring that the knock sensor wire was white, but where it pinned into the ecm , the wire was black. lol.
