As Iclick mentioned, my bike and Heatwave's bike are TBW while Iclick's is not. The calibrations are built on different strategies. They cover the same ranges but are just broken up differently. Don't get hung up on the different columns but you can use them for comparison.

Guys. Try a tuning trick.
First, change the vast majority of your AFR table to 14.6 and do a data log.
Using MegaLogViewer HD to plot VE Front and VE New Front and in the third box pick RPM.
Do you get a straight line or is it a real fuzzy line? If you are getting close on the VEs, you will get a straight line. Similar to when in open loop, plotting MAP and INJ PW F and RPM in the third box.
Way cool stuff.

Yes, it does have the ability to turn on and off Closed loop under limit and switches.

In a previous post I asked about changing the entire AFR table to 14.6 for tuning runs, but was cautioned about doing that in the higher RPM/MAP areas without adjusting the spark advance to avoid possible engine damage. Does this only apply to the upper ranges or does it also apply to lower ranges? IE, if I decide to change (in the future) to open loop in the cruise range should I be concerned with spark advance...or any other items?
Dennis or Whittlebeast, do I need the registered copy of megalogviewer to get graphs like Dennis posted? I downloaded the trial version but can't seem the figure out how to get it to plot like the one posted.

Do you have the version from this site? A normal Google search most likely gets the Megasquirt version.

If you decide to go to open loop, you will be going richer and would not have to be concerned with the spark advance.
I used the unregistered version, just open your log, click the scatter graph tabs and select the 3 data signals to plot.
