I have been playing around with my new SCT2 from Evolution. Hooked the SCT2 up to a laptop for datalogging. Yikes... a zillion things to plot, and many of them I don't understand. Plotted "Load".... Anybody know how Ford defines/calcs this? Plotting it vs. RPM, Speed and various other params did NOT show a good correlation. Plotting Load vs. MAF voltage showed the best correlation, but still with significant standard dev. Load is obviously a multi-variable function of many other parameters. I may try a multivarible curve fit later, but figured somebody might know.....

How does Ford calc Load?

Where do you find Air/Fuel ratio in the Ford OBDII data (i.e. what is param name), or do you have to calc it from MAF and fuel flow data?

Is there a site that lists all the available data logging points and explains what they are?

Also was suprised to see spark advance as high as 40 degrees... which only occured at lower RPM's... anybody know all the params Ford uses to calc advance??
