Chipping kit for Honda OBD1 ECUs

THESE INSTALL INSTRUCTIONS WERE MEANT ONLY FOR BUYERS FOR KITS BOUGHT FROM THE FOLLOWING TWO EBAY MEMBERS.

Kits bought from other sellers linked you to my site illegally and most likely will not work for your kit anyways because components do differ from seller to seller.

Remember as advertised in the auction if you are not experienced with electronic components as well as soldering and desoldering then this kit is most likely be too hard for you to install, please seek the assistance of someone experienced enough to install this kit.

First make sure you have everything as seen in the picture

Step 1: Desolder all the pins holes for C51, C52, IC3, IC6, R54 and J1. If any of them already have something in them then leave it. Also, if your ECU does not have a spot for the resistor to go in R54, please throw the R54 resistor away as you will not need it.

Step 2: Install the components in C51, C52, IC3, IC6, R54 and J1. The polarity only matters in IC4 and IC4. My kit alone does not include a SST chip as seen in the picture. Underneath it is the socket. The notch will represent pin 1 on the IC3 socket and IC4 chip. Pin 1 faces left.

Step 3: Make sure all the components in red are installed before starting your car

If you get solid CEL and the fuel pump does not prime and the car does not start pull out your programmed chip from the socket and reseat it more carefully. Make sure the correct pins are going in the socket as they are supposed to.

If you get solid CEL and the car starts but is running extremely rich. Make sure the 0 ohm resistor at J1 is installed. J1 enables the secondary chip that you just installed and if J1 is not installed then your ECU will revert back to its emergency code meant to get you home if your ECU fails.

If you get a specific code make sure you ordered the correct chip. Example: Adding vtec to a P06 will give you vtec but will not give you a knock sensor therefore unless the knock sensor is disabled on your chip then you will get a code. The same goes for a P28, the P28 does not support the knock sensor either.

If your VTEC is not engaging but you get no CEL make sure your programmed chip has vtec enabled. If your using the same chip you had before you put this kit in then most likely VTEC will not work for you until you get another chip.
