7.3 WHEEL SPEED SENSOR SETUP
Use the jig for setting the wheel speed sensor (AT0042). Using a pair of 13mm
spanners, set the wheel speed sensor no closer to the pickup point than the thickness
of the Wheel Sensor Gauge (2mm). The pickup point is the end of the brake disc
bolts on an SR3. When fitted, check the sensor is working by ensuring it is plugged
in, then turn the power on and spin the disc, the sensor should light up when it sees
each disc bolt. This is shown in the image on the right.
7.5 BALANCING THE THROTTLE BODIES
To set up the individual throttle bodies, please follow these rules:
When the engine is idling at around 1600rpm, the Syncrometer reading needs to be equal on each of the
individual throttle bodes and the TPS should be 4.0%. The TPS value can be seen on a computer connected to
the ECU or it is displayed on the dashboard. When adjusting the TPS ensure the engine is turned off.
This is achieved by adjusting the idle speed screw and throttle body adjusters.
Ensure that all four of the bodies open fully and evenly.
During this procedure it is essential that you have a laptop connected, with PTmon displayed. Check the
engine coolant temperature is a minimum of 50°c and maximum of 90°c while the engine is running.
7.8 COIL PLUG ORDER
The order of the coil leads is shown below, when re-fitting ensure there is a positive click onto the spark plug.
1+4 is near the plug and 2+3 on the opposite side.
