Add this to your cart if you are sending in your ECU to have the PWM Components added to your OBD1 ECU (P28, PR4, P05, P06, P72, P75).
Currently PWM Boost Control is compatible on eCtune, S300 and Neptune using this circuitry which is normally used to control an EGR lift solenoid.
PWM Boost Control also requires a solenoid to be installed in the car. We stock and use both 3 port and 4 port solenoids along with fittings and line kits which can be purchased on our website as well.
Please see our SHIPPING INFORMATION Page for instructions on how to send in your parts to us.
