[fg conversion pats removal]

I had a similar problem make sure the 12V source to ECU is not just when cranking but when the key is also in the run position.

 

[REMOVING REAR O2 SENSOR]

Set the following to No Error

auF2164    P0136 - Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 2)
auF1845    P0138 - Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2)
auF1127    P0141 - Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

If you have a V8 you need to set the Bank 2 Sensor 2 as well.

Then to disable the rear o2 logic itself set the following to 1
auF2440    Calibration switch that will disable FAOSC  (DISABLE ->1 or ENABLE -> 0 )

If you want to disable the heater output for the rear O2 sensor (eg you have the plug chopped off or some other reason) then you can set the following to 0 for the appropriate sensor

auF12158 EGO heater  hardware present switch array.

Cannot find scalars:-

auF2440

auF12158

to disable them what am I missing ?

 

I also changed auF0011 to 0 no rear sensor is this required ?

Think I will just stick to the BF ECU and assume the other ECU never had the PATs disabled.

Only have enthusiast version so do not want to waste credits.

I have two ECU's available for my Barra conversion into my Jeep TJ. One was supposed to have had PATs disabled and second O2 sensor disabled. This ECU has no pins on the third connector and the label is damaged the numbers I can read are ........A650-BB I think it is a BA ECU. I assume having no pins on 3rd connector is that it was for manual gearbox. Have tried this ecu engine will not start and fuel pump does to activate while cranking. Have tested the fuel pump circuit and it functions OK. It is just not getting the ground from ECU on pin B27. Which I have been told is a sign that PATs is not disabled.

The second ECU is from a BF ute with BTR 4 speed. 5R29-12A650-CC.

Is it possible to read both ECU's without licensing them. I just want to view them and decide which ECU is best to use with my conversion.

The engine is a FG Mk11 have the pedal out of the BF ute installed and the trans is the Jeep manual trans.
