PGM-I combined the individual CDIs and included an air correction system.

PGM-II integrated the CDI and RC Valve systems.

PGM-III has 3D mapping, with a G.P.S. and separate maps for each gear.

PGM-IV has a cosmetic card instead of an ignition key, and took a step backwards to a single map for all gears!
