There are 2 tables in a GTP .bin file that control the OL/CL functions.


1.) Delay vs. Engine Coolant Temp.

What this does is says "if the engine coolant temp is xxx degrees, it will switch to closed loop after xxx amount of seconds." Obviously, the colder the motor, the longer the wait time for the transfer from OL/CL.

2.) Closed Loop Enable ECT

This just says "if the coolant is above xxx degrees (I believe the stock table is set at 68*F) then it will automatically enable CL."



Hope this helps
