Hello everybody. I am new here and have built my Speeduino 0.4.3c. Unfortunately I have a problem now: The two temperatures cannot be calibrated. The MS version is 3.1.03 and the firmware is 202005. Firmware was loaded via SpeedyLoader including speeduino base tune. Arduino is a Mega R3. With GM pre-setting of both sensors and without a J4 connection, IAT is above 120 ° C and ECT is above 80 ° C. They do not move when a sensor has been connected but only a little while the sensor pin is shorted to ground. Interesting: The IAT temperature drops when I remove the VR board or when JP4 is closed. Arduino alone without Speeduino shows both between 60 and 100 ° C. Does anyone have a solution to this problem here? Thank you.
