All I can say is WOW!!
What a great program.
Won't make much sense to anyone not running and trying to tune MegaSquirt but if you are I can recomend this program.

It allows you to examine all aspects of a captured log file and re-run it graphically in real time on your laptop whilst viewing the VE and Timing tables.
Also analyses your VE table against your AFR and tells you by what % you are hi or low of the targets in each bin.

Brilliant.

Oh and it looks the dogs danglies to anyone looking over your shoulder as well

So that's what you were doing!

It is a very good application and can show lots of info relating to the engine and fueling, I used it to get my fuel map somewhere near right fairly quickly.
I havent had any luck with Megasquirt tweak 3000 however as i couldnt get it to open the files correctly, so gave up and just tuned from datalogs manually.
