Adding EFI to your 5 yourself

When I decided to EFI my 5 my first plan was to see what the minimum cost would be to carry out the conversion. And to see how easy it is to do and is it possible to make your own inlet manifold.

First thing I looked at is pros and cons

Pro’s
Better fuel economy
No more carb freeze
No carb
Cold starts
Warm starts

Cons
Cost (around £1200 installed yourself to £1600+ to have all the work done for you 2013...

I installed connectors at all the sensors for ease of maintenance in the future. This will also help with your testing along the way to make sure there are no gremlins lurking about.
As I was using the adaptronic setup you can download the software from there website. Upon first start up of wari you will need to follow the on screen instructions for setup . You will need a base map on the computer you want to use as if you connect to the ecu there in no information there. It is at this point you open wari using the base map and then connect to the ECU. Once you connect to the ecu it will download the base map to the ecu.
Once complete press f11 this screen lets you see what the ecu is seeing. And lets you test the injectors and triggers. Also press f2 to bring up the live gauges to see that the tps and other sensors are working.

The instruction book you download with the software contains all the help you will need if you get a bit stuck and explains in great detail the workings of the ecu.

Now turn you ignition on you should here the fuel pump relay click and the screen starts to show voltages ect.
To test the fuel pump set up is ok. Place a 12v lamp between a ground and the feed wire that is the fat white wire. when you turn on the ignition the light will light when the fuel pump relay is activated.
Do not connect the pump until the next steps have neen carried out.

Now you can test the injectors one by one using the injector test function.. (See screen prints below). A click should be heard on each one.

Now we can check out the TPS and triggers.

Looking on the live gauge screen you can see TPS. When you press the throttle this should read how far open the throttle is. Once you foot is fully down the flag on the ecu date screen should go green to indicate wide open throttle. Now release your foot the gauges should go back to how they started.

Trigger 1 TPS sensor.
Now turn the ignition so that the car turns over. Trigger one should go from green to yellow to show that the ecu is seeing the flywheel turning and changing the value of the sensor.

Trigger 2 second sensor.
This will be the same as trigger one. But it needs to be turned on by the following. Click on triggering on the main wari screen
Then click on triggering settings.
Trigger 2 needs to be set to digital and the reset box needs to be ticked.
Now click apply then ok.

Afr gauge.
This will be seen on the f2 live gauge screen.





Now carry out the final connections to the fuel pump. When you next turn the ingnition you should hear the pump come to life. Check what pressure you’re regulator is seeing. This needs to be set to 3bar and now is the time to check for leaks.

Its worth noting to check the bracket for the fuel tank vent one way valve as mine was rotten causing the valve to close and the tank kept pressure.

Now connect the coil pack and you are ready for turn over. Hopefully at this point the car will start and run. This is where my story ends.
THE CAR WILL NEED TO BE FULLY MAPPED by someone who knows what they are doing.
On the base map I was able to drive the car for mapping.

I used EFI parts for this as chris had supplied the ECU and other parts and was close to where I live and knows a lot about the r5,s 1.4 engine.
