Gday toyo lovers currently looking to touch on some higher boost in my jzx81 maybe have a play at 16psi see it then back it back down to a daily setup of around 12 13. The electronic signal from the fcd will raise the fuel cut level to accommodate for the additional boost without triggering fuel cut andor an engine diagnostic light.

Hks fuel cut defender wiring diagram. Wire strippers or scissors pliers 10 mm socket and handle. One for power and ground wich is easy the other 3 is the problem. Any help on anyone who has given this a go with their 1js would be very much appreciated. The hks fcd is an electronic device developed to properly raise the factory fuel cut level on factory turbocharged vehicles to a safe and higher predetermined point. Which wires do splice into for the air sensor rpm and air signal going away from the ecuhelp some one. The hks fcd is an electronic device developed to properly raise the factory fuel cut level on factory turbocharged vehicles.
The fcd installation is designed to be easily integrated with the vpcf con or factory ecu harness. As modifications are made to optimize engine performance the factory fuel cut is often triggered by higher boost levels which activate a fuel delivery cut off as a failsafe procedure. From this it appears that hks fcd setting 9 would result in fuel cut around 174 psi and settings 7 recommended by hks and 5 are off the chart requiring boost pressures well above the sensors practical output 49 volts 174 psi to engage the fuel cut mechanism. Now there is 5 wires. The modification of this signal means that the ecu no longer sees what it considers to be excessive boost levels. However i cant do this with the factory 147psi boost cut and have decided to go down the path of the jaycar diy kit they have.
Ok trying to wire in a hks fuel defender. Hks fuel cut defender installation manual 137 kb 13th oct 2005 hks super afr installation manual 394 kb 26th oct 2005. With a fcd fuel cut defender connected up to the map sensor this clip shows how the map sensor output voltage is clamped by the fcd and will not go rise higher than 42volts. Hks fcd itself cannot control fuel.

A fuel cut defender or fcd is a small electrical device which modifies the tps turbocharging pressure sensor signal received by the ecu.
The install of the hks fcd is straightforward procedure and can be installed by any average mechanic.
