spark timing behavior question I was monitoring my car's tune yesterday and I noticed something intersting.
I started monitoring at 30 mph in 1st and ended at the top of 3rd (6600 rpm). What I noticed, is that on the onset of WOT the timing jumped to 40* advance and then eventually worked it's way down to 33.2* ... then suddenly in the middle of the rpm range, it dropped to 27* for a moment then back up to 31.3* where it moved around between 30* and 33.3*. This happened in all three gears.
I immediately suspected KR ... so I checked that sensor. The whole time, it recoreded 0 KR. Is this normal behavior?? Can anyone tell me what's going on??
Last time i monitored it (on a dyno pull), it started at 33.4* and moved down to 32.5* with 0KR. Which is what I expected to see this time around.
Any ideas or comments???

Can you e-mail the files? If they are not EFILive files can you export to Excel?
