b16 with stock internals, EG intake mani and thotle body. header and exhaust not much else done with it.

 

P30 if you're using the knock sensor. P28 chipped with a P30 program if you're not.

 

well, im not wure if im using a knock sensor or not...its obd1 if that helps...

 

If it's a stock B16, there is a knock sensor on it assuming that no one has removed it and it hasn't taken any damage in transport. If that's the case, a P30 ECU is your best choice; I'd really recommend using the knock sensor for safety. It's not the greatest knock sensor, and it can get confused by the resonance of some types of aftermarket pistons, but it's a great safety net on a fairly stock engine. The P28 ECU is the exact same ECU as a P30, but the P28 lacks the knock sensor board. The stock program in the P28 is obviously different, which is why it needs to be chipped with a B16 program if you want to use it.

The P30 will give a CEL if the knock sensor is unhooked. If you're not using the knock sensor, a chipped P28 is fine because the knock sensor has to be disabled in the P30 program in order for the P30 program to run in the P28.

 

so thats all, just a check engine light?
