Bluetooth OBD Adapter DIY project.

Postby Soundstream_626 » November 3rd, 2015, 10:25 pm

Just thought id share a lil project I did recently. my car is an 08 impreza hatch. I have had it for about two years and have done a few diy mods to it. Nothing too technical. This is the car:

Image

Recently my lambda oxygen sensor started to act up, it has to do with the catalytic converter efficiency. I tried decatting but I still get the error just less frequently now. I bought one of these OBD bluetooth adapters:

Image

and I wanted some sorta permanent display in the car so I bought a lil verizon phone with a 4.5 inch screen for 20 dollars off amazon. I also bought the full version of the torque app. The app is ridiculous. Alotta options for clearing codes, real time displays such as boost, RPM, voltage, etc and it can also log data such as fuel efficiency and distance etc. I highly recommend it for hobbyists looking for an inexpensive monitoring solution.

I ended up fabricating this lil mount for it:

At first I made a lil frame for the display with some old 1/2 inch ply I had laying round and used expanding foam to set it in place and fill the large gaps.

Image

Then i trimmed down the foam and added some filler.

Image

i needed to catch that curve hear the shifter properly so i had to do that part in car.

Image

added the lil wings to the side trimmed and sanded.

Image

and finally wrapped it in some leatherette.

Image

this is how I have the displays I want set.

Image

now I realise it would be more practical to have the gauges or whatever display further up but for my application, I just need the fault clearing ability but I have also set it to log fuel efficiency numbers etc. check out the app options. The adapter works great for me and for 10us you cant go wrong.

Looks good man.

I'm planning something similar soon. The expanding foam method is quite effective.

yeah you can change the units of the various displays in the settings.

km/h or mp/h for speed
Nm or ft lb for torque
gallons or litres for fuel
cfm or gms/sec for airflow
psi or bar for boost etc

if your gps is enabled you can check 0-60/ 0-100 times

you can also check throttle position, AFR, oil temp, rpm, fuel rail pressure etc amongst the more popular options and there are dozens of others. Basically anything you have a sensor for and your ecu is reading.

you can also choose the type of display whether dial or graph etc.

you can also set it to HUD mode like this

Image

I never really tried it this way though.

Theoretically it should work on any car with an OBD II port. Works on my impreza and my cousin`s almera. Try different apps tho. Lotsa free ones in the playstore.
