Ahh no ecux here but I'll get that information and post it tonight after work.
As far as mods go. I'm on an ams a-box, neuspeed exhaust, stock dp's, a darintake with a stainless filter, and water/meth injection.

Right now I'm at a little over 50% with yellow heet. Adding toluene lowered cf's down to 12.3....
The wideband idea might have to happen here pretty soon. What's the going rate for one of those now? I assume I only need one. I don't think it's the knock sensors themselves because I can barely hear a tick on accel. Also both banks are showing similiar cf's.

Interesting....
Well, I personally use the Innovate LM-1. I think it is under 200 bucks now, but there are LOTS of really cool wide band 02 sensors out there. And yes, I just use one sensor. I have always wondered if my second bank runs the same way....
Also, if your a/f checks out, and your sensors are ok, I would start researching seafoam to clean that engine out. Maybe you have a nice build up of carbon on your piston and you are running a really high compresssion ratio? But, now that I think about it, water injection is supposed to keep your engine super clean, so maybe not....
There aren't to many things other than what we talked about that can cause knock. Things that mean your engine is f*cked.
Good luck, I hope you get it figured out.

Ok pulled more fuel and now I'm at 9 max.....This is more like it...
I ended up at -3.5% primary. I tried -4 and +1.5 deg timing and cf's went up to 11.3. I think I might settle on -4% primary and mess with the pump pressure on the WI. It will be interesting to see where my cf's are without the meth/water.
