Autoshift:
Autoshift Mode
: Defines the mode used. See below.
Activate after (rpm):
After which RPM, Autoshift becomes active. RPM must be over this value to start
and, when active, If the rpm drop below this rpm, Autoshift is stopped. Please note that this is NOT the
rpm where GCU will shift the gear. That is defined in
Autoshift at
. Only used with 2 stage Autoshift.
While TPS over (%):
This is the minimum TPS that needs to be set in order for the Autoshift to work. If
TPS drops below this value, Autoshift stops.
Autoshift at (rpm):
At which RPM GCU will shift up.
Activate after 2nd gear:
If this option is enabled, shifting 1-2 is done manually by the driver and
Autoshift will only work in 2-3 and higher. Only used with 3 stage Autoshift.
Autoshift Mode:
3 Stage
In order to use this mode, ECU must support launch control. GCU (Pin G1) will send »Launch« request to
the ECU and ECU input must be configured that when this happens, ECU goes into the launch mode
(Limit the RPM)
Procedure to start:
- Holding Autoshift button for more than 2 seconds, activates the Launch control. GCU sends active low
(ground) signal to the ECU via G1. ECU Must be able to enter Launch state. LED will be blinking slowly.
- While still holding the Autoshift button, we accelerate to a point that we don't need the Launch mode
anymore to accelerate freely (car gets enough grip to be able to push 100% throttle)
- We release the button and GCU deactivates the Launch mode (Pin G1), turning the Launch mode inside
the ECU off. LED is blinking faster.
- GCU will autoshift to the next gear when RPM is higher or equal to
Autoshift at (rpm)
. If
Activate after
2nd gear is
enabled, it will only shift when in 2nd or higher gear. Driver needs to shift to 2nd gear in this
case manually by the paddle.
- Autoshift will continue to shift for as long as TPS is higher than
While TPS over (%)
and Paddle
up/down is not pressed. If TPS drops under the
While TPS over (%)
or up/down is pressed by the driver,
Autoshift will stop. LED is turned off.
