Just so you're aware, I use Celcius for temperatures. To convert into Fahrenheit you need to change to expression to the below:

Code:

expression="(x*1.8)+32" to_byte="(x-32)/1.8"

      <description>When vehicle speed is the same or greater than the second value, the closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When vehicle speed drops below the first value, other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'CL to OL Delay' table. In this case, depending on the delay value, the 'CL to OL Transition with Delay (Base Pulse Width)' and 'CL to OL Transition with Delay (Throttle)' are used to determine the open loop to close loop transition and vice versa.</description>

      <description>When the engine load is the same or greater than the second value, a counter value is incremented. If engine load remains equal to greater than the second value, the counter will be continue to be incremented and if it exceeds the 'CL Delay Engine Load Counter Threshold' value, the primary closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When engine load drops below the first value, the engine load counter value is set to zero and other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'CL to OL Delay' table. In this case, assuming a non-zero delay value, the 'CL to OL Transition with Delay (Base Pulse Width)' and 'CL to OL Transition with Delay (Throttle)' are used to determine the open loop to close loop transition and vice versa.</description>
