Hello, I would like to control the fan via PWM. The water temperature is transmitted via CAN from a Holley Dominator. I am unable to change the Min, Max, and Step values in the table. I want the fan to run at 25% at 60°C and at 100% at 70°C. Mustang.pmu (5.2 KB) [Screenshot 2026-07-15 184503]

Assuming this is a CAN channel as you have noted the channel name. Set your steps value for how many cells you need. The X axis channel needs its units setup correctly. Meaning if its a voltagle unit you may only use 0-5v or if a kpa absolute you wont be able to negative values etc… Next thing the …

I simply cannot change the min/max/step data. The values -177.0 and 0.0 are always set automatically. The unit is also set. [Screenshot 2026-07-16 065652] As soon as I change, for example, just the decimal place for the CAN input, the min/max/step values can no longer be modified.

There is an issue when a Canbus input has a float type. I will check it and try to apply the fix soon.

There is a workaround for you if you do not want to wait for the fix. Change the CAN_Wassertenperatur type to a type other than float - create the table, set it as you need. At the end - change CAN_Wassertenperatur to float again.
