and there are over 50 market classed suzuki sold world wide, even in 1 year.
50 smog laws.
all this is dictated by the countries laws on smog, 100s of ECU, for each. 1 each for smog zone (market) 1 for M/T or A/T or 4wd, and more. vast ECU exist world wide
for one reason the software (firmware ) is in ROM not FLASH memory as all are now.
The modern ECU has 12 injectors, in the ecu, (drivers) that can be enabled in firmware, at any time, reducing the amount of ECU for spares, to 1 ECU.
Your ECU fits 1 engine, and can not be reprogrammed,
the mass of the SPI injector is not near the same as any MPI injector. it behaves totally differently, (not just flow, rates)
Do you know what dead time is?
its the time in mS (milliseconds) before he injector coil can move the pintle valve open, the do not work the same in this 1 regard. (same with release time)
not only that but your car ran a 10v injector SPI and MPI runs 12v. (the resistor gives this fact away)
