1992 – 1995 JDM Honda Computers Performance Chip Installation
This covers the Honda JDM “P72“, “P30” and “P08“.
Installing a performance chip on 1992-1995 Honda JDM computers uses the same method as described on other posts on this website. You may use the search function above for those other publications. What differentiate the installation on JDM ecus from USDM, Canadian, European, Australian and some others, is the need of installing Surface-Mount-Devices (SMD’s). The same installation kit of the P28 and other OBD-I Civic / Integra ecus is needed, but the parts are smaller. These parts are; the 74HC373 chip, the “J1″ jumper and the two bypass capacitors, which instead of being a through-hole mounting devices, these are soldered on the surface of the circuit board. They are smaller and a little bit more difficult than their counter parts, but still, it is a simple job. The resistor “R54″ is not needed on this installation and the two capacitors are optional, so the jumper and 74HC373 latch chip will be depicted only.
Here is a picture of the 74HC373 SMD Chip
