Swapped it ... same thing happens with my ecu , fan still comes on so I’m guessing there is a problem with the ecu and not the kpro.
Can it be fixed ?

No 2 completely different ecu

Yes sir ... same exact calibration

i haave a kpro v3 in a prb ecu when i turn the ignition on the fan automatically comes on and it will not read the o2 sensor. Borrowed a friends kpro v1 and everything works as it should. o2 reads and fan comes on only when it reaches the set temp. So is the Ecu damaged or is it the kpro?
