Been playing with i2 at the track quite a bit lately, a killer prog for analysis.
Looks like these rFactor guys have figured out how to build the data files i2 uses.

ecuxplot is a very handy tool and seems some even use matlab for some of the more advanced stuff. I have no idea if possible or how
difficult it would be, but if this could be replicated or adjusted to work with ME7Logger, I think it would fill the gap very nicely.

Looks like motec doesnt like this kind of stuff though, kinda like how apple feels about hackintosh.
