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?
