Mystery KR - 2004 GTO
Usually only take it up to the end of the ¼ - Today a little more - - -
This "homemade" graphic shows the KR for the 1st scan

For those that like the "real" thing - - -

The stock (mv) are naturally NB, but even reading low - the AFR seems pretty rich ?
--------------------------------------------
Here we are after I kicked up the PE FAM - - -

Now the KR "moved" down to 1st and 2nd ???
The car runs strong - no ping or any kind of knock that I can hear.
Anybody got any ideas ?
Thanks - Ken
