Re: Spark Plugs?
Denso? Ok, works for me... That looks 2 heat ranges colder?
Yea, I'm seeing some knock (+2volts raw), not really sure if it's phantom knock, or if it really is there. I'm in the process of building some det-cans to hear for myself, but the spikes are sudden, steep, and above the rest of the "crowd" of signals in the area.
I too was hoping running E85 that I wouldn't need anything colder, but I'm going to try to make this engine last at least through the season, so I'd rather be safe than $orry.
I'm running 24psi, and I don't know what my ign was, I'll have to look at the maps tomorrow when I'm back at the shop with my laptop. I do remember compared to just about everything else that I looked at it was pretty retarded. I tuned it to hang out 11.4-11.6 AFR under boost, but I noticed that on the last EVO that we tuned 10.5 netted us +3-4 deg of timing, and quite a bit more power.
I just got a new AWD dyno, and provided I can free up some time on it, I'm going to try to stick it on there this weekend and get some play time in. I just wanted to get the stupid things like plugs out of the way....
UPP
