Computer Head Unit
 

I would like to add gauges for when I add a supercharger (oil temp, oil press, boost, air fuel). However I do not want to touch the dash, pillers, anything that is not pre-existing. So I was thinking but don't know how to do it and looking for help/direction.

I was thinking of using a Raspberry Pi (mini computer) connected to a touchscreen that will use stock radio/speakers, stock Bluetooth, and let me display and change the car gauges. Then build it into a box that will replace the existing head unit.

Is that possible or should I wake-up from this dream.

easiest solution is to get an OBD2 - Wifi converter and run software on an iphone or andoid.

Im running 'dash command' via Kiwi PLX adapter, and my head unit displays gauges, info etc..

Much less hassle than a car pc, been down that road ;p

Do you have problems keeping the phone in place. Not flying in your face while turning/braking ect. How did you mount your phone.

I assume he uses some sort of phone holder :happy0180:

yeah, its in a holder.. didnt come loose last motorkhana, was all kinds of sideways ;p

Hey, I just wanted to let you know, your dash is backwards. Might need to warranty that ;)

** fixed

Lol!!

Hey, buddy, I think the numbers and words on your head unit look funny. I didn't realize that you guys have a completely different written language in Australia. I wonder if there's anything good on MA radio, we don't have that in the states. I do have to compliment you on your excellent English, you write like a native speaker.

Get this thing. I will, when I supercharge.

It looks like you can only one gauge on at a time. So I would at lest need two (air/fuel and oil pressure) to keep my car from blowing up.

Is it possible to change the analog speedo to read differently then the digital speedo. That way you could use the analog as a air/fuel gauge?

just replace the drivers side A pillar piece with a new one w/ gauge ports.

As I mentioned in the beginning I dont want to touch the dash or pillars.

I made my own complete dash on a previous car and I swore I would not do that again.

buy pre-made piece and keep oem incase you want to go back. its going to be the easiest route.

Any reason you haven't considered one of the many Android based head units were talking about here? The Ca-Fi knock off running Torque would give you all the gauges you could want.

Heres what I did on my Civic. Unfortunately this would not be possible with this car, at least not yet to my knowledge, until more open ecu tuning solutions become available. (or a good standalone)


I've got a touch screen with a VGA input (single din, although we'd have much better selection with our double din slot)

Then a netbook in my glove box running windows xp, that hooks up with a usb cable to my ecu. The ECU's software on my netbook (Hondata Smanager) allows me to tune on the fly, display any of my sensors values in a gauge display that i can customize, etc. I've even got an electronic boost controller that i can adjust psi and boost by gear on the fly, or just load a different file with preconfigured settings instantly.

This whole setup cost me 800 bucks (not counting the 100 i spent on the netbook)


I cant wait till a proper tuning solution is available for these cars.

I also had a pre-made A-pillar case. The problem I ran into was all the wiring to the 8 guages I installed Signal, power, ground, light. I would like one central location. Also I dont like the look of pillar gauges anymore.

I didnt know android had their own head units. A quick serch and this is what im looking for http://www.mazda3forums.com/showthread.php?t=412874 minus the carbon fiber

Now I'll have to find out if that will work with the Bluetooth connection already in the car. i.e. the mic.

Look at either the TUN21A which is the Ca-Fi knockoff for around $400 or the T7019A which fits more OEM and can also be had for around $400. Both support GPS, run Android 2.3, and can work with Torque via a Bluetooth OBD2 reader. Search for 2ForMe on here and you'll find a wealth of information.

Gadget, what are you using to drive your AppRadio? A cellphone?

iPhone 4S for the moment

I'm using dash command as well through my 4s and Pioneer head unit. I even downloaded a skin to look like LFA gauges.Attachment 42846

how do you find the appradio2? i keep getting tempted to buy it for $300 but i really want to wait for the new one....

Does anyone know if there is a way to use an OBDII wireless adapter to communicate with the Subaru BRZ's Pioneer AVIC 930 head unit? The head unit would have to be able to load the Torque Pro softwre and I am not sure if this has been done or can be done?

I run dashcommand on a dashlinq CT headunit. They are cheap and work good

You can always resort to a mobile solution that is cheaper than the head unit replacement but more suitable than a cell phone. You can use an iPad, some of the Galaxy tabs from Samsung and the Nexus 7 (2012 and 2013) http://gt86mounts.com/product-catego...-tablet-mount/ . Be aware before getting the OBDII adapter that IOS doesn't support the Bluetooth one. I use a Nexus 7 2013 in my car and then I take it with me. I've had the mount in my car for over 18 months without issues. I run both Dashcommand and Torque pro on it.
