The 2g's all use the same injectors. 5 speed and autos use the same ecu. A awd ecu will work in a fwd, and a fwd will work in a awd. A 95 eprom ecu will work fine in a 95-96. If you put a 95 eprom ecu in a 97-99 car, you need to swap the spark plug wires and injector plugs.
1 becomes 2
2 becomes 1
3 becomes 4
4 becomes 3
Reason being the cam sensor is on the opposite side of the head. There are very minor differences in the awd vs fwd programming. The awd does not have speed cut, the fwd does. The awd rev limit is a little bit higher, like 300 rpm, and a couple other things. The differences are so minute, most would never notice the difference.
BTW $150 is a steal for a clean 2g eprom ecu. I mainly part out 2g's and have sold several of these ecu's from $150-$250. GLWS.
