Logs of individual cyl with O2+WB

[rr]

Ah yes, see it now. Must have been late as I didn't even
realize that the engine is under some serious boost.
As your logs show I'm always amazed at the afr changes
when the throttle is lifted. First it goes way rich as
the excess fuel is used up, then goes way lean as the decel
enleanment takes affect.

All in all the graphing looks nice. I've started to use
Excel for this stuff and it truely makes a difference. I
like the vertical data-point line. Makes it real easy to
pull the data together.
