Not mentioned in usual comparisons is that lh2.2 starts with just a flick of cranking whereas 2.4 always needs a few engine rotations to verify via the flywheel position sensor (58 hole count and 2 missing) before firing up.
2.2 doesn't use a hole count system, just a hall sensor in the front ign distributor. It was an interim system introduced when strict anti pollution laws were introduced.
Finally LH is the fuel side of things that's easy to remember, whereas it's the EZK ignition system that controls the spark.
This is wrong
Lh2.4 in good condition will start faster than lh2.2
This is simply due to the better ignition maps and fuel maps
Lh2.4 only requires on average 90* more engine rotation than lh2.2 which is not noticible
Most issues with hard starting come down to bad fuel filters and bad fuel check valves
I have an lh2.4 240 that is in good condotion and it starts instantly every time
Ezk is part of lh2.4 and cannot run on its own
It depends on a digital signal from the ecu that is unique to the system it is an optional module to the lh2.4 eco system much like the apc system that saab used
