We installed the new Greddy Profec B replacement into a 1992 - 1996 Turbo Honda Civic.



This unit is for sale currently in the US and readily available

The Tools you will need to install the Greddy e-01 into your turbo vehicle

• 10mm ratchet
  1 Phillips screwdriver
  1 Standard screwdriver
  Wire Strippers
  Solder Gun
  Electrical Tape
  ** Or taps if you do not wish to solder

The unit itself has tons of little harnesses and addons.



First we will handle all the sensors and installs in the engine bay. First locate your Greddy Pressure Sensor shown in pic below



Mount your pressure sensor somewhere in the engine bay away from as much heat as possible and have the nipple pointed downward. We have it mounted here temporarily until we mount our boost solenoid.

• Make sure your pressure sensor is mounted with nipple pointed downward.
  
  If you are installing into a Toyota 2JZ, or Mitsubishi 4G63, make sure to tap the pressure from the line between the intake manifold and the fuel pressure solenoid.

Then Locate your Greddy Stepper Valve.



If you are setup for external wastegate use, you will tee into the "CN" and "COM" ports using the preteflon threaded fittings provided in your Greddy box.

If you are setup for internal wastegate use, you will tee into the "NO" and "COM" ports using the preteflon threaded fittings provided in your Greddy box.



Screw the base plate into the stepper valve using the 2 screws provided to you by Greddy.



Mount the stepper motor in a safe, dry, cool place, use the rubber grommet Greddy provides for you and put the hex bolt through the rubber grommet inbetween your mounting point and the stepper motor itself.. We mounted ours right by our pressure sensor

• Make sure to use the rubber grommet! this is to ensure that the sensor does not suffer from premature failure by shock.
  As with all boost controller installs, make sure that the vacumn lines you use are not kinked, twisted, excessively long and are secured via zip ties or hose clamps.

Run the "COM" port of the stepper motor to the internal wastegate. Run the "NO" side to a pressure source. Either your compressor housing itself or an intercooler pipe. We have ours tapped into an intercooler pipe.

If you are running an external wastegate, run the "COM" port to top of your wastegate and the "NC" side to related pressure source.

Next, run a vacuum line from the pressure sensor to a tee given to you by Greddy. One end of the tee will go into the pressure sensor, the other 2 will be spliced into your fuel pressure regulator vacumn line.



Make sure to zip tie to secure the lines teed into your fuel pressure regulator vacumn line.



Next locate your ECU.



For the install you will be working with the Greddy Control Unit, and 4 wires off the main power loom.



Plug your Greddy Power loom into the control unit and then start teeing into the appropriate wires.

Red for 12v power. Tap this into your stock ECU power. For this install, the customer is using an AEM unit. we tapped into wire A23 shown on the wiring diagram below

Wiring diagram for 1992-1995 Honda Civic.



Black wire for Ground. We also tapped this into the ECU ground. For this install, we tapped into wire B2 for ground shown on the wiring diagram



The Brown Wire is for RPM signal. This wire must be tapped into an ECU signal for this to work correctly. We tapped into the MSD unit tach output the first time. The Greddy unit didnt like it. After retapping it into the AEM's RPM signal it worked just fine. Make sure to tap into your ECU to make sure of the rpm offset feature.



Plug all your sensors into your control unit. And mount it securely, zip tie or clamps to make sure none of the wires interfere with your vehicles operation.



And the keypad into the monitor, and mount both units away from your airbag locations.



Double check everything in the engine bay. Make sure all fittings are secured and solid. Turn on the car and enjoy your new e-01 boost controller! This boost controller can do a multitide of different tasks, from rpm selectable boost to connecting to a e-manage unit and passing vital engine and boost parameters back and forth.
