11F0 Board - OBD1 Honda ECU VTEC Conversion Kit Installation

First desolder all the spots on the ECU marked, C60, J10, Q101, IC14, & D11.  They may be hard to find, but they are there.  If a component is already in the ECU, do not remove it or replace it with a component we have supplied.  Some ECUs have these parts already.  In the past we used to include a 10k resistor for spot R201, but we never found one ECU without it, so we stopped including them.  If you find an ECU with a blank R201 spot, please contact us.

In spot IC14, solder in this part.

In spot Q101.

In spot C60.

Note the + and – symbol, these are polarized.  Install them correctly.

In spot R201.

In spot D11

In spot J10,

In the past we used to include a resistor but we NEVER found an ECU that needed one.  If you find an ECU with a missing R201 resistor, please contact us.

Pay attention to the direction of the diode. If you need help look at the other diodes on the board.

Use a leftover piece of a resistor or from the diode legs to jumper this spot.


Please check out the original instructions on the PGMFI Wiki for further help if needed.
