Sample calculations:Uin = 4.94V, Uout = 4,05V, Rk = 10000 (10K)Rx = 10000 * (4.94 – 4.05)/4.05 = 2197 ohmWhen you are using the additional temp

Attention !The sensors’ calibration doesn’t write down the settings in the device’s memory, it only generates the calibration curve! Intake air tempe

InjectorsThe DET3 device has 2 power outputs with the 5A load each. Because of this, we can connect to each of them 4 high-resistance injectors or two

ATTENTION! Exceeding the outputs’ load limit (5A) will lead to the damage of the power outputs, what may cause the permanent opening of the connected
