7.8 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 on the dashboard. Ensure the engine is off
when adjusting.
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.
