Right so the tuning saga goes on with my XR8, had it down at Ford today to their ECU guru to see why the SCT flash tuner wont talk to the car. Turns out there is something funny with the ECU, its in some mode that wont allow them to write to it, but this is the 3rd ECU that has done it, so it must be something else in the car. Any ideas?? they have logged a tech support request with Ford Aus, but given its an AU, they doubt any support is still available.
I got them to check why it is running rich while they had it. Couldn't find anything out of the ordinary, but he commented that with the Herrod headers, the O2 sensors where only reading the rear two cylinders on each bank (one branch of the Y), and so weren't seeing the whole picture. Firstly how big an issue could this be, and poeple out there with after market headers, where are your O2 sensors located?

My difillippo 4 into 1's retain the 02 sensor in the factory position, i did have to extend the wiring loom for the passenger side one about an inch but that was done by cutting the tape that holds the loom behind the engine in the bay back a bit and just allowing the wiring for the sensor to go down that little bit further.

The factory position for the sensor is after all 4 header pipes meet, but with the HMS headers, it only were 2 headers meet, so its only half the picture.

If your cylinders in your engine are in good condition..spark and fuel is all perfect then it wont make a big difference.

Get new sensors if they are original because they would almost be stuffed if your car has done over 80000-100000km

Yeah this is where I was going with asking how old the sensors are. Mine have done 85,000 and the thing is running richer every day. Time for newies.
