R34 GTR models are wired with their trigger (engine position) signals wired in opposite polarity to other models. To allow for this four dip switches have been provided on the ECU.
Set the DIP switches according to the diagram below:

GTS-GTR ECUs that have a bottom PCB version of 1.2 onwards also have a jumper for setting the scale of TPS Out. The ECU sends the TPS signal to the Automatic Transmission Controller and 4WD Controller.
For factory manual gearbox vehicles set the jumper to the 1:1 position, for factory automatic vehicles set the jumper to the 2:3 position. |
Note: The GTR uses a fuel pump speed controller that utilizes two auxiliary outputs from the ECU. See PCLink help for information on how to set this up.
