OK next question. Possibly for Mark.
What application is tune map 4? Is it possibly for UK cat cars with aircon?
Have a car that is running map 4. Thought it was possibly dirty contacts etc. on the resistor (White) or duff value but no . Resistor OK and runs map 5 on a test ECU with the white resistor still in the loom. Somehow suspect the ECU has a problem.

Its a bit vague, its a non cat map, listed for 4.2 Europe or 3.9 Gulf states. I think some of the export engines run lower compression ratio and a different map accordingly.
But you don't know of any way the ECU is reading a white Map 5 resistor and then running map 4?The normal white felt-tip marking on the case of the ECU is '4.0L Cat'.
