Do you have an ol .gdf (diacom) of it?.
That would be fine.

Expressed as what (where;s the labeling for the actual mph)?.
I think the scale shows the max as 6,500 for rpm, but I'm guessing, and I
shouldn't have to do that.

I'm not impressed trying to read excel stuff, and usually just buzz by it.

So do I, ya wanna give me a larger one?  a 21" Flat Screen would be about
right.

If the plugs are looking reasonable then that's fine.  Have you done any
performance testing thou?.

Takes a while, like reading plugs, fine art, etc,

RPM, TPS, MPH, O2, KR, should about cover it for diagnostics
Pulse width, degrees advance, KR, O2 are then great tuning items.

Then if you see a specific problem, easier to zoom onto other stuff MAP/MAF,
FP testing then brining other tools to bare.

Using things for specific reasons, makes the data more mangeable, least to
me.
