Re: b16a2 vtec not engaging......
A p28 is an ecu for a single cam motor. Is it a chipped p28? If you can get a P30 it will be a better bet. I believe the one out of a car is a P2T.

Re: b16a2 vtec not engaging......
its most likely not chipped. i had the same problem with one of my old motors. i would recommend you get a computer for that motor and then get someone to chip it and give it a good base map if not get the computer you have now chipped. btw just got mine back from a freind who did a kick ass job on at a great price. if interested let me know.

A OBD1 P28 ecu will work just fine as it is the most commonly used ecu for swaps. You do not necessarily "need" to chip it if the motor is stock or even with the basic i/h/e. You need to verify the wiring is correct. With a DMM set to continuity insure you have a good connection from the vtec solenoid to pin A4 and Pressure switch to D6 of the ecu harness. I would highly recommend going over all other pins as well, it seems the previous owner did not do a very good job of wiring.

Yes correct, but just because the OP has a 2000 civic si motor doesn't necessarily mean he has to use the original ecu. The P2T is obd2 and will look for the immobilizer function,secondary O2 sensor and others. Since the OP has a 95 civic chassis, it is not equipped with those functions and will throw a CEL.

Get the ECU chipped with a P30 program (with the knock sensor disabled) at the bare minimum.
