No wideband yet :( I need to stop being lazy and spring for one but I have to take time to research which i should pick up. I see what youre saying but I dont THINK PE would make a difference here. Since PE is based on throttle position and a few other perameters that im not even hitting!!! This is happening at like 20% throttle Im not sure of anyone that uses PE mode at that early on in the throttle position...kinda defeats the whole Stoich. My PE mode under normal circumstances when its not turned off, is on at 60% + throttle position. You should be able to run Stoich in all ranges safely if youre not hammering on it and have the correct timing and VE set up...Ive had this same spark timing/ PE tunning Technique for 4 PCM's but NEVER with this OS...This is the first time I've ever seen KR with this motor and tune style. I think there is a difference in the knock sensor settings vs my old OS...but im guessing if the sensitivity has been set this way from factory on this OS then i will tune based off of its sensitvity because it is probably more accurate, or simply safer!!
EDIT: Im looking at my old OS vs new OS... there is clearly a huge difference in the older Knock settings vs the new one...Just about every knock setting is different and some by a fairly large amount. The sensitivity is definitely higher on the new OS, Ill just re-tune accordingly
