Im wondering which wire is the fuel cut feed on the MY99/00 cars?

Also, does anyone know how the signal works?

Im assuming that there is a sensor on the engine that sends a steady voltage signal to the ECU. When that voltage is exceeded then fuel cuts out???

no.. it will fuel cut due to excessive boost, or excessive maf voltage..
there is not a specific pin for the fuel cut it is internal to the ecu determined by the inputs it monitors..

pinouts are here but I don't think it will be of use to you

Hol if you let me know what you are trying to do then I will probably be able to help out, ecu pin.

Simon I don't recall you asking me if you could copy from my web space ?

You know you have ... identical MY99 ... all I need is you to say please can I and you are welcome to anything if its of use but please don't try that on.

You have PM to discuss Bob.. I was not aware it originated from your website.

Here's another pinout from my site ;o).....
ECU Pin-Out 1999-2000 (Page 1)

You can use a fuel cut defender attached to the Pressure Sensor input to the ECU on an MY99/00. This will allow boost to be increased (by tightening the actuator). I done this sort of thing years ago.....

But beware that the 99/00 ECU also uses the MAP and MAF voltage to calculate load, so by fooling the ECU into thinking you are running less boost can cause you to be too low on the ignition/fuel map which can lead to detonation.

Thanks Guys,

I have what amounts to a voltage stepper device that fools the FCD.

Im just trying to work out how!

anyone have the pin-out for a 55plate WRX??
