secondary o2, crank position sensor, fuel tank pressure sensor, i believe there is also an extra evap sensor near the intake manifold.

obd2 = the devil

Chipped p28 doesnt look for one unless the person who made the program added a provision for it.

Need more than just software changes. Knock on a P28 needs hardware mods to the ECU (knock board, etc...)
