This functino retuns a pulsewidth time (in tenths of a ms) given the following:
REQ_FUEL
VE: Lookup from the main MAP vs RPM fuel table
MAP: In KPa, read from the sensor
GammaE: Sum of Enrichment factors (Cold start, acceleration). This is a multiplication factor (Eg to add 10%, this should be 110)
injOpen: Injector open time. The time the injector take to open in tenths of a ms
