Civic EG

Hey guys...
i have one question to do...i ask to many people but never found an answer correctly...
Usually i found in engines (b16A2) p30 ecu code or p28....someone told me the difference is in chip...its more fast to process the information of ECU...

now...i have in my car an P29 ECU...i never found the specifications of this ECU or the original engine of them...
the car redline is in 8500rpm like usual and have a HP normal...

thanks

p29 i believe is the 86-89 Acura Integra. with the ZC DOHC /D16A9 DOHC motor. it's redline is at 8500 RPM it's chipped.. for a p29..

i really dont know anything about this ECU but one thing i know....this ecu isn´t chipped...

once i go to a friend to chip my ecu and i see that it wasn´t the socket to put the chip.

thanks
