No sorry that wasn't clear. At certain RPM ranges the injection cycle starts BTDC (when RPM is higher). At lower RPM ranges the cycle starts ATDC.

We have scoped the system at various loads, rpm ranges, throttle positions, and starting. What I have specifically commented about was a dyno pull from about 1500 RPM to the rev limiter. What happens during cold start etc. is different and probably something only you would enjoy hearing about
Our testing just basically confirms much of how you thought this DI application is being used.
