09 TSX fan control not working

I used a base map from hondata to flash into this 2009 tsx AT.
The fan control does not work according to what i set, its works only from 94 degree and stops at 87 degree.

i set it to 90 degree and even disable the second ECT sensor but still does not work.

The other issue is the throttle map as shown is a base given by Hondata, after flashing in the car was slow like a tortise.

I checked the datalog and saw that when request for 15% throttle pedal the throttle plate only opens 4 or 5 %.

What could be wrong, most of this base maps work well, is there a problem to the throttle map?

The temp at the 2 sensors is not the same. The temp the fan uses may not be the one you are seeing the reading from.

Automatic calibrations have no adjustment to the throttle plate actuation.

Post a datalog and the associated calibration showing the issue.
