Fuel Pulse Width

I got my dev board measuring the fuel pulse width today.
Here's a quick pic of pulse width against rpm and afm volts:

More details to follow when I've had time for some more investigation...

Stock Rev Limit

I started looking at the fuelling on the stock ECU today.
The first thing I did was look at where the RPM limit was.

It looks like the ECU stops injecting fuel above 7197 RPM, and doesn't start injecting fuel again until the revs drop below 6935 RPM.
