BTW Here is what Barry from SDS sent me for changing from °F to °C (Did not yet):

EM –3/EM-4 SETUP MODE TEMPS


Unplug hall sensor plug from ECU.
Power up the ECU with the programmer plugged in.
Momentarily ( ½ second ) short out pins 6 & 7 on the hall plug port on the ECU using a wire or setup tool (provided by SDS ). See drawing below.

You will see SETUP TEMPSENSOR in the programmer window.
Choose one of the following by pushing the +1 button until the correct sensor is reading in the window.
