Hi Everyone.

I've been lurking around OzFoz for a while now but never really had anything to post. Figured it's about time I shared some of what I am up to given the amount of advice and information I've collected reading the forums here. Until now I think my only posts have been in the buy/sell/trade section.

About 6 months ago I picked up a bog stock MY00 GT Luxury to replace a MY14 WRX I'd just sold (changed jobs, commuting via train and it was basically only driven weekends - wasting away). GT was in pretty average condition, heaps of dints, bit of paint damage from previous owner, few bits and pieces missing etc. Cost me about $4000 and I had no intention of doing anything with it… But you know how it is.

Anyway since purchase it's become a bit of a project. I don't have photos of it in it's original glory however as I've become more involved I've started getting the camera out more often.

One of the first mods I installed was a 3-gauge pod in the centre of the dash. Problem is, it's big and bulky plus it bothers me that the background colour and the general gauge style don't match stock gauges. The more work I do on the car, the more I am inclined to keep things looking as stock as possible (especially the interior).

I had a shop around for gauges to match but they were either too expensive (for me) to justify purchasing, or just couldn't find anything that I was 100% happy with. So, decided to develop my own.

I've worked a bit with the Arduino platform (open-source electronics development) previously, so I figured I could build a system that reads sensor values and can display on screen in whatever format I desire. Basically trying to keep within the following constraints:

- Match factory style (green backlight, not obnoxiously large etc.)
- Display data in a manner that was readable and valuable whilst driving
- Interface with the Interceptor to get ECU data
- Interface with wide-band O2 sensor (and controller: 14Point7 open-source)
- Retain use of the dash storage compartment

I considered building stepper controlled gauges however it meant being restricted to particular data (e.g. only fit 3 gauges across and they are limited to whatever scale they're created in (eg. PSI/Volts/Temperature etc or whatever it may be). Also, the thought of creating a backlit scale frightened me - so scrapped that idea.

Then I started looking at LCD displays. Initially wanted to use one large display but couldn't find anything with a big enough resolution/size with a corresponding Arduino library.

Ended up deciding on a two-display setup, similar in format to the 3-gauge pod but with two LCD displays that could be changed dynamically, or display information from multiple sensor on a single display. Apologies for the crude sketch:

Image

Before getting too involved, I ordered a couple of LCD screens (12864ZW) with a resolution of 128 x 64. They're 3" image-capable screens (not just text). I'd like slightly larger, with higher res, but there's a limit to what the Atmega can support, plus I intend to run both off a single CPU. We'll see how that goes, I can separate if required. They were about $12 each, plus are backlit green (very very close to the stock gauges):

Image

After finding the library they were pretty easy to program. The photos below show a basic data layout (which will likely change), with the ability to display a number in it's raw value (e.g. a temperature, or a voltage). Plus, for values such as Boost or AFR where a bit of a history is important, it's laid out in a horizontal gauge format, with peak hold:

Image

Image

At the same time I had also been researching options for wide-band O2 sensors. Everything I came across was a professional product and even senders alone I was looking at well over $200. In the end I stumbled across 14Point7, where they manufacture professional senders and gauges, but also have an open source version that requires assembly, but costs about $30. I bought one along with a Bosch LSU 4.9 wide-band sensor. Cost me about $111 USD (so probably close to $170 but included the sensor). Works perfectly for my requirements as it outputs a linear voltage between 0 and 5v which I can ready with one of the Arduino's analogue inputs. It has a screen (so I can debug) but when running I will disconnect it:

Image

So, confident that I can display the info in the correct manner, and interface with a wide-band O2 controller, I mocked up a really really crude template to check for clearance and general size etc. Notice the LCDs are slightly tilted toward the driver position:

Image

Image

This is where it stops for the time being.

To-do:
- Create housing (my original thoughts are using a polystyrene block cut to size/shape with the dremel, the fibreglass over the top - however I'm open to suggestions!)
- Interface with Interceptor. After reading up on it, the Haltech is compatible with CAN data bus. I have not yet got to a point where I know what channels are available, however I know it's version 1. I ordered a CAN data bus module which has arrived but haven't progressed past that.
- Install wide-band O2. There's a bung in the exhaust so it's ready to go, I just haven't had a chance. Also - not good to install the sensor without running controller as it heats the sensor to avoid condensation damage and carbon build up. Probably the last thing I do.
- Finalise the data display, might include buttons to cycle through gauges etc. Not really sure at this point. When I get a prototype into the car I'll have more of an idea of how it reads.

More to come soon.

Yesssssss!
Love what you're doing with the gauges. I'm doing something similar (also with 14point7 hardware and a bosch 4.9 ;)) but I'm using colour TFTs and aiming for 1 DIN high. Will probably start with this gauge display code. I'm mainly interested in EGT (off cylinder 4) and wideband AFR, as I have a 3 gauge pod with other stuff.

a big +1 for the arduino nanos. Tiny little things are so useful, especially at ~$5 shipped via aliexpress :o

Love the GUI design so far, is your code up on github or similar?

[edit] You might be able to use this as your display housing, if your screens are small enough -- https://www.subarugenuineparts.com/prod ... cts_id=722

I LOVE where this is going!

I wonder whether your displays would fit in the 'navigation pack' holder that was available for SF? I believe the same console was used as the gauge pod on the equivalent year Impreza.

ie.

andrew_k - Yeah I did think about using colour screens, mainly because there were a few types available with much bigger resolution at about the 3" size. My concern was that the higher resolution would introduce latency and cause the info to be unusable e.g. hitting the boost limit but you're not warned until 2s after the event. I'd be really interested to see how that instructables code performs given that only one gauge is displayed rather than multiple. Is the O2 module you're using the open source or did you get one of the pre-made models?

The nanos are brilliant. I bought a 10 pack or something and I'll never go back to the standard Uno (or whatever it's called). No code anywhere as of yet (it's still in "hideous prototype" format ) but I can send you a copy if you're interested.

I'd like to get the measurements for that gauge pod housing, anything beats having to fabricate my own enclosure. Are they available in Aus?

tryangus - I have seen those before, trawling through Gumtree or something I came across a forester that had one and I had the same thought - haven't had any luck sourcing one (not that I've tried very hard).

Looks like the 'navigation pack' is the same housing as https://www.subarugenuineparts.com/prod ... cts_id=722

Anyone know of anyone who actually has one installed? I'm wondering if it's a full DIN - if so, might be in luck. Looks like the screens would fit but the PCB might hang out a bit much.

The gauge housing I linked to is the one in the photograph above. Ignore the photo on the site, as it says in the description **SIMILAR to photo shown**. It's the same one as in tryangus' post. The usable space is 1 DIN - 50mm x 180mm. It's not available in AU as far as I'm aware, but even if it were it's an OEM item so you'd still be better off shipping it in than getting it from the Subaru Aus. Waali has one in his 02 GT, if you ask him really nicely he might be able to take some further measurements for you.

For measuring things I need instant display of - eg boost - I'm still using analog gauges. For the TFTs I'll be using 1 small one per nano, with them displaying EGT and AFR. I think a min/max/current style display will be sufficient for those measures.

Ahhh fair enough - so you retain the analogue gauges where timing is a factor.

Thanks - If that pod is 1 DIN then I might be in luck. Screens are just over 50mm high and the PCB of each is 90mm wide. PCB height is 70mm so I need 10mm top/bottom to fit them in, but just looking at a photo now of an empty unit including the vent assembly and I'd say there's enough room. I'll ask Waali nicely ;)

Just attaching this for reference. It's the Haltech CAN BUS v1 protocol - which I understand is used by the Interceptor (and Platinum Interceptor). Took me ages to find as they only seem to publish v2 for their newer (post 2012) stuff. Unless the firmware on the Interceptor can be upgraded...
