HI Kerry,
I contacted Gaspar today as I am having trouble getting into the relevant sub menu. This is the reply I got:
1) Go to subparameters of the ecu (pres the buttons 3th on the left
> and next 1th on the left during power up)
> 2) Set parameter 2 to zero.
> 3) Switchh off and on again the ecu.
> 4) check the read temperature (must be over ambient). Calculate the
> error and divide by 2.
> 6) Set parameter 2 to the calculated value.

I don't know if I,ve got got a different ECU (1yr old) but my menu has START,INFO,RADIO,RUN and I cannot see a way of getting to any menu that adjusts the EGT ambiaent temperature.
