A kit for adding a PWM output to pin A11 of the ECU to communicate with an electronic boost controller.


It is then possible to perform boost-by-gear (variable turbo pressure depending on the selected gear). This feature is well supported by the HTS software.


The kit includes:


  • 1 x MOSFET transistor (Q29)
  • 1 x 220 ohm resistor (R70)
  • 1 x 330 ohm resistor (R71)
  • 1x 1N4002 diode (D14)
  • 1 x PNP transistor (Q20)
