Having KR issues and losing MPH - EFI Live files Can anyone take a look at some EFI Live files to try and help me with my Knock Retard problem?
It's falling on it's face in 4th with KR heading up to 3.8 or so, and timing advance dropping to 18-20!
Now I know why my et's and mile and hour are sucking so much wind lately!
Thanks to my buddy Andy (Spydum) for the help.

These are in CSV (Comma Seperated Value) Files.
Mods are (and I mean everything!):
Air lid with K&N
Free Ram-Air Mod
New TR55 plugs gapped at .050
3" Dinomouth Catback
MAFT Plus
As far as the motor goes, that's IT!
Runs were last Sunday and in the 13.2 range at 106-107. My best on a 75 degree day was a 12.7 @ 110 a few months ago. It was HOT out as well - IAT was in the 90's for the most part. The first was a baseline without the MAFT. The I richened it up on notch (WOT) on each of the following runs to try and reduce the KR. Helped a little, but not enough...
Any ideas?

Re: Having KR issues and losing MPH - EFI Live files Looks to me like you're running lean at WOT (looked at run1)
Averaging .797 .809 for your 02 sensors
need to richen it up a bit try 2-4% at WOT...see what happens then. It should resolve the timing issues
