Boost Controller OBD1 ECU Chipping Guide
What Is Boost By Gear?
Boost by gear's primary function is to prevent traction loss in lower gears. Boost by gear enables the control of boost pressure levels for each gear. Some gears you may want to decrease the boost psi to keep traction, where's other gears you may want to increase the boost pressure because you have enough traction and want to make more horsepower. The idea is to be able to push the pedal to the floor and not lose traction, boost by gear enables you to do this.
In order to boost by gear with the OBD1 ECU you will need to add several electrical components to the main OBD1 ECU motherboard. If you have already completed this step and would like to install the electronic boost solenoid, you can find that installation guide HERE. To do the boost solenoid installation you will need to purchase a boost solenoid, vacuum hose, cable ties, 22g wire, soldering kit and heat shrink wrap.
What Do I Need To Make Boost By Gear Work?
What Electrical Components Do I Need For My ECU To Work With Boost By Gear?
When running a boost solenoid with a chipped Hondata, Neptune or eCtune OBD1 ECU you will need the following electrical components. Transistor E3055T 314, PNP Digital Transistor DTA143XSA, 1A 100V Diode 1N4002, 220 Ohm 1/4 Watt 5% resistor and a 330 Ohm 1/4 Watt 5% resistor.
