A vehicular gas turbine engine includes a first electronic controller responsive to a plurality of engine operating parameters and associated with a power relay box to control operation of engine functions and further includes a manual controller that allows open loop operation of the engine to start and run it at a speed and power level independent of the electronic controller and associated signals of engine parameters. The manual controller includes a timer set to shut the engine down after a preselected time period of manual operation to prevent excessive use of the open loop control thereby to minimize possibility of engine damage.
