Would like to know any info about this for some reason side of case says stage 1 chipped p28 buti don't see a chip I've compared to some stock ecu pics and only found slight difference but it was on harness side not over where I see pics of chips installed thanks for any response as I just acquired a full donor car and removed everything I needed to swap this d16z6 into my 2000 civic ej6

 

No info to be told. You have no chip at all. Talk to the individual you bought it from and hash it out.

 

Thankyou for responding didn't buy got complete swap for free just pulled ecu and what it said so wanted to know what I had to work with b4 I wired it all up into my car no idea why someone wrote this on their wasn't previous owner so maybe a past owner bought it and got screwed...

 

A stock P28 ECU will run a D16Z6 just fine... you don't need it to be "chipped". All you will need is an OBD-2B to OBD-1 ECU harness plug adapter.

 

Possibly. You can run the ECU stock with a jumper harness loom as just mentioned, but if you want "performance", you can't just get a general "chip" and expect magic, unlike what the interwebz tells you.
