VN and VP Holdens 1988-1992

VN 215,180 units, VP 92,860 units (both V6 and V8) produced.

All use the 1227808 ECM which is equivilant to Corvette's 1227165,
but without U2 (the SXR chip), limiting them to 160 baud ALDL data.
The 1227808 also comes in the short case, the 1227165 is in a long
case (the 1227752 is a 1227165 in a short case).
