what i do is export your data to excel (all you really need is rpm and injector pulse width), then create an extra column with =RPM*IPW/120000 and then format it as 'percentage' and you'll have injector duty cycle for every sample in your log. then you can use excel's MAX function to find the maximum value, and then it's a simple 'find' command to find when it happened (so you know if it occurs on max boost, or high rpms, or something of that nature)

That's a badass table, man I can't wait for 2.0 anymore. I guess I have no choice really
