Notes 1) The Z32 uses a switch on the TPS (Throttle Position Sensor) to sense closed throttle. R33 RB25 S1 does not. The Z32 ECU will use default “li

Important Soldering Notes If you already have the equipment, you should know how to use it confidently. Tools Required Temperature Controlled Solder

1) Knock Sensor inputs – pin 23/24 The R33 RB25 engine uses twin knock sensors with Nissan part number 22060-56S10 (shared with R32 RB20DET). Z32 V

2) O2 Sensor inputs – pin 29/55 RB25 uses a single O2 sensor. Z32 uses twin. Link the O2 sensor input for RB25 (pin 29) to pin 55 so both O2 sensor

Remove R613 Surface mount component resistor 4) Fuel Temperature input – pin 36 * Series 1 and Series 2 Z32 ECU uses a fuel temperature sensor

Bottom side of ECU put 2.2K ohm resistor in parallel to R252 to put Z32 ECU Fuel Temp input to a valid reading. Add 2.2K resistor inline with ECU R

5) Exhaust Over Temp Output – pin 33 * Series 1 and Series 2 Z32 ECU uses this line to drive the FICD (Fast Idle Control Device) – for idle up wh

Series 2 Series 2 has the FICD wire connected to pin 36. Cut the track to isolate pin 33 so the EGT lamp does come on when the FICD activated. Do t
