OK, why would the fuel mixture be rich if push start the vehicle. Are you saying its because of the low battery voltage.

As long as ECU is able to identify TDC and related timing regarding injection and ignition, I don't see any difference between a push start and cranking using self motor in a car with reasonably healthy battery.

All of this is read from online forums where people listed their experience - never tried this myself or know anyone personally who did and fried his catcon.
