•
Yellow #3 wire
(pin 13 of the 16-way connector) must be
connected to the throttle input corresponding to the Motor 1
input.
•
Yellow #4 wire
(pin 14 of the 16-way connector) must be
connected to the throttle input corresponding to the Motor 1
input.
•
Green/red wire
(24-way connector) is and 5V output used to
feed throttle and pedal position sensors. It must be spliced and
connected to both of them.
•
Sensors negative can also be spliced between pedal and throttle
position sensors. Connect it directly to the battery’s negative
terminal.
•
White numbered wires are sensors signal inputs, connect them to
the signal outputs of the pedal (Pedal 1 and Pedal 2) and throttle
(TPS1 and TPS2). After connecting these inputs, it is necessary
to calibrate throttle and pedal as guides chapter 15.1.
•
Pins 13 and 14 (16-way connector), yellow wires, will not be
used for electronic throttle control, they can be set up as auxiliary
outputs..
14.1 Connection table – throttle bodies and pedals
Check the throttle and pedal wiring before disconnect it from the OEM
ECU. If you need, contact our tech support to get more information
about throttles and pedals.
With the electrical connections ready, go back to chapter 7.5 and insert
the throttle code (FT) that you found on the throttle table connection
If your throttle is not listed in our table, it might be necessary to send
it to our tech team to have them check compatibility and research
its control parameters. In this case please contact our tech support.
Sensors and Calibration
15.1 TPS calibration
IMPORTANT:
To perform this calibration, it is very important
that the engine is not running, because the
throttle is fully opened and closed
Through FTManager, click in the TPS/Pedal button
15. Sensors and Calibration
This chapter has the final steps before the first engine start. It basically
guides the user through checking sensor readings and calibrating
engine actuators.
Ignition calibration
Engine temperature
Oil pressure
TPS/pedal calibration
Air temperature
Fuel pressure
Sensors and Calibration
Go to “Sensors and calibrations” and then “Calibrate throttle/pedal”.
1. With the pedal on idle position, click button “calibrate” besides
the field “Idle: 0%
2. Push throttle to the maximum and click “calibrate” button besides
the field “WOT: 100%”.
3. Press “Save”. Message “Calibration done!” is shown if the process
is ok.
4. In case an error message is shown, check TPS connections.
TPS calibration errors may be:
Inverted and calibrated:
means the TPS is connected the wrong way,
but is normally working. If wanted, check connections, but, know that
it will work normally connected this way.
Possibly disconnected:
check TPS connections. Maybe there is a
broken wire or one of the connectors does not reach the TPS pins.
Check with a tester to see if the voltage on the orange wire varies
according to the throttle position.
