I'm always up for suggestions.  ;^)

I'll upload the actual data if you want, or I could send it to you.

The MPH is on the graph.  The RPM is on the graph.  

What exactly would be most helpful for you to see the data?  Be specific
(like KR)  It starts coming up from about the middle of the graph.  Do
any of you guys have Excell?  I can upload that file for everyone.

I think your screen is too small.  ;^)

BTW my duty cycle on stock injectors and stock Prom shows over 80% from
6000 - 6900 RPM.  Is that bad or ok?  The top is 86%.

Thanks for all the help!  I'm a newbie and this is really helping my
comprehension.  I am actually getting to see data from my car and not
someone elses. 

I can make a graph with the data fields attached to the HTML and just
the data fields that you want.  Also what would be the max screen size? 
If it is too small then a graph is hard to read (hence the large size
for multiple datasets)

Consider me your servant (so you can read this stuff more easily)  After
all you guys are nice enough to help and look at it!

Thanks!
