Hi

Have you installed your fuel cut defender, I'm in the process of installing one "JAYCAR" and I'm trying to locate the wire that goes from the MAP sensor to the ECU. Could you help or can some one help by pointing out the Pin number for RB25DET ecu.

For R33's (GTST's at least) the MAP sensor is to the left of the brake booster, near the firewall, looking from the front of the car (little black box with a vac line running to the inlet plenum)

I WAS UNDER THE IMPRESSION WE USED AFM NOT MAP SENSORS ON THE R33GTST AND THE BOX WITH THE VACUM LINE WENT TO THE FACTORY BOOST GAUGE ? oops sorry about caps

Yes, they use an AFM, BUT there is still a MAP sensor, whether it be for boost readings only or not, I don't know.

99.9999% sure it's a MAP sensor

Thanks guys,

You have been some help, but what I need is to install this Fuel Cut Defender to the factory ecu, I'm not sure which wire gos to the Map Sensor and to the ecu. I just want to increase boost.

any ideas

It will be easier connecting it to the MAP sensor AT the MAP sensor rather than trying to decipher the wiring at the ECU. There are 3 wires at the MAP sensor - I can't remember which one is the signal - PM rio228 as he just installed one recently
