Auto-start Throttle Settings and Engine Cut AT-START Levels LV2, LV3 Only
DEFINITIONS:
Auto-start: A pre-set throttle position, less than full throttle, to be used for the
initial acceleration off the line without having wheel spin. When the trigger is
released, auto-start is turned off and throttle operates normally again.
ATS: Auto-start status.
Engine Cut: Shuts the engine off without having to adjust the throttle trim. Takes
the throttle servo to a preset position when the switch is pressed. (Not available
to models using braking/reverse from the throttle servo. Primarily for boats.)
TG.P: Trigger point at which auto-start is activated.
PRST: Preset throttle servo position when function is activated. Preset is a
“true” preset – it is not a mix or a portion of the EPA. It is truly a
command to move the servo to a set position regardless of other inputs,
including trigger.
MODE: Which function is being utilized at this time. (Engine cut and auto-start can not be used together).
AT&SW: Auto-start is activated by throttle trigger or switch. Switch can be assigned in FUNC-SW (pp. 34-35) and
used to turn on/off the auto-start feature without having to pull or release the throttle trigger to do so.
INH: Inhibited. Function is electronically inhibited and will not operate until changed to another setting.
SW: Switch operated. Auto-start is inhibited and engine cut is available. (Assigned in FUNC-SW, pp. 34-35.)
AVAILABLE FOR: Throttle servo only.
ADJUSTABILITY:
MMOODDEE
: Inhibited, switch only (engine cut), auto-start with switch override (autostart).
AATTSS
: Inhibited, off (not available until set), ready (will activate on next trigger pull), active (operating now).
TTGGPP
: Inhibited, 5-95. Default: 5.
PPRRSSTT
: Brake 100-1, 0, Forward 0-100. Default: 0.
Auto-start may be assigned to a switch. Engine cut must be assigned to a switch to operate. (See FUNC-SW, pp. 34-35.)
INTERACTIONS:
EPA has NO effect on the preset position. The preset position may exceed EPA. Be sure to set auto-start after setting EPA.
Servo reversing DOES change the direction of the preset in this function.
No other function affects the preset except servo reversing.
Trigger position has no effect on engine cut. Engine cut will shut engine to the preset position regardless.
Auto-start must be restarted for each use by going to the auto-start function and pressing the + and – keys together
for one second while ATS is selected, or assigning and holding on a switch. (See FUNC-SW, p. 34-35.)
If throttle triggered, auto-start remains active once started until the throttle trigger is returned to neutral.
DESIRED END RESULT: Avoiding wheel spin on starts and shutting engine off safely.
CAUTION: Remember that preset is not relative to EPA, so always check for binding if other changes have been made.
