As I stated there is no difference, only the slight posibility of a momentary pulse difference.

The computer changes strategy from firing injectors once an ignition firing in firing order to firing twice an ignition firing at smaller pulsewidth all at once.

You could probably see the event if you looked at the O2 sensors. But only briefly as fuel trim is, maintained and the system stays in closed loop.

The need for sequential firing came with OBDII rules that required shutting down misfiring cylinders fuel input. That couldn't be done without shutting off the motor if they all fire at once which is the way it was done up till about 94-5 in most cars. MB changed to LH in 92 for this specific reason. No way to do this with KE.
