    A/C Removal and Fan 1 is always on

    Hi all,

    I removed the A/C system from my engine and I believe the missing A/C pressure sensor is triggering the Engine Cooling Fan to be on all the time. I read the forum and it seems the common solution is to add a pressure sensor and just let it sit, seems the open circus is triggering the fan to switch on.

    I do believe this car is somewhere sold without an A/C but I don't know how to set this up in HP Tuners. Settings and Log file attached.

    Looking forward to any help!

    Try setting this whole table to 0, together with the A/C Disable TPS set to 0% and Re-Enable TPS set to 200%. Alternatively you could bypass the sensor with resistors, both 2 pin and 3 pin ones.

    Yep, that worked.
