This one has got me stumped......... I have been tapping the car for almost 2 years and now all of a sudden the friggin' computer does not log but a few of the WOT events......WTF? It logs everything else but only 3 to 4 lines of WOT data. Has this happened to any of you other peeps? Kinda pissin' me off wasting gas trying to see where everything is with the new tuning!!! Let me know...any help or suggestions mucho appreciated.
What do you define as WOT?
Cell 22 is the main WOT open loop cell. But the PCM
will not use it if there is some emissions stuff going on
(like evap purge cycle?). Also on my '02 FBody, the
FTC bins are set from factory so that there is no way
for you to see cells 2, 3, 6, 7, 10, 11, 14, 15. Your
"other" WOT cell is cell 13, which can also be active in
closed loop (only TPS>94% will distinguish WOT in this
case).
So try and sift the data in Excel by TPS rather than FTC
and maybe you will find more of them?
If you don't find TPS>94%, though, that's an entirely
different (like cable slack and/or bump stop) problem.

Are you using a USB or serial port to log? If using a serial port, test it for proper data flow or switch to USB and see if there is a difference.
Good luck
