Also, Does anyone know how the 'two mode fuel injection system' works??

Yes, it pulses the injection once every revolution to i think 3000rpm then double pulses the injectors after that.

If u mean switching from semi-sequential to simutanious, then semi-sequential is it fires one group of 3 inj. no. 2,4,6 in the first crank rev and 1,3,5 in the second crank rev of the 4 stroke cycle. does this cause ET eng, having larger inj, fring all inj twice every cycle as in simutanious makes for a too short a pulse. Switchs to simutanious at higher revs/load cause there's only one timer and it would overlap! Hope thats helpful. Some original photos have not been recovered yet.
