Hi,

i changed the parameters of fan speed and shift points between the gears for my sierra 2014, and loaded the updated tune successfully, however it did not change anything in the car. the fan speed is still the same, and the shoft points are still on 5200 rpm.

the only thing the worked with me is to remove the speed limiter.


please advice.

please attach the backup and last tune written to this post so we can verify the changes are being made. Thanks.
