Hi John,

I believe that you have the 605 ECU as per your description. (see the bottom of the sticker)

This is the way I understand what GASPAR has said:

1) Set trim low and enter in submenus by turning Power on the ecu and click first on "+" button and next on the "menu down" button.)

2) Move to parameter 2 and set this now to ZERO.

3) Switch off and on again the ecu. Take note of the indicated temperature. Will be higher than ambient.

5) Determine (calculate) the difference and divide by 2. For example, if it read 48º and the real temperature is 20, the diference is 28, divided by 2 = 14.

6) Repeat 1) and 2) and set parameter 2 to the determined calculated value (14 in this example).
