JetCat SPH5 User Manual

Setting up the ECU
These are the first steps you need to complete before operating the v4.0 ECU. Make
sure your batteries are charged, the ECU is off and the GSU is connected.
Do not perform the calibration of the temperature probe if this is a new engine.
Temperature probe calibration is for ECU updates only.
Calibrate the temperature probe.
To compensate the differences from engine to engine there is an offset number that is
used to correct the temperature displayed. This offset is derived by sampling the actual
temperature read from the engine compared to the ambient room temperature.
Your engine should be at approximately room temperature, 21 °C.
Press and hold the Select Menu key on the GSU, then switch on the power.
* Remark:
Instead of pressing the Select Menu key on the GSU, the little key on the LED
board can be use instead.
