I'll do more testing on the Kat when I get back out to the track...
Yes ...the Iphone app. is Very close on the 1/4 mi ET, can't ask for better than that !
But on MPH it is off 11.92MPH in the 1/4mi. That is not good at all, So for 0-60mph runs it would be off App.6.66 MPH...That's way too much.

Bottom line: the app. is great for ET. but no good for MPH.... You need MPH to get 0-60mph times.

I hope you get to ck. the KAT Matrix at the track.
I know it is NOT 100% accurate but, My guess is it may be off app. 2 MPH in the 0-60 run.....& Not 6 or 7mph like the app.

Also as you said, Quote:
Remember, no times are considered totally ligit unless there's a time slip attached. The Kat Matrix timer is a pretty good tool for comparasons but is not (IMHO) a certified register of 0-60 or 1/4 mile times. No offense guys (I have one too) but it just don't count unless it's done at the strip....
---------------------------------------------------------------------------------------------------------------------
I do agree with that 100 %.................
I use the KAT to see the VAST difference the weather as in the DA makes on the times.... Plus the SMALL difference the Exhaust & intake etc. make.
My KAT Matrix has been pretty consistent in my 39: 0-60mph runs even thou it is NOT 100% accurate for sure.
