DTADroid - The Android App for DTA ECUs
By: sparrow Date: June 4, 2014, 3:22 pm
---------------------------------------------------------
I hope Jason doesn't mind me posting this. Delete if you want
to.
Before I talk about the app, I want to say a massive thank you
to Trevor Page (Trev16v) who has saved me months of work by
helping out with this. He's effectively handed over MSDroid to
enable me to build an Android app that works with DTA ECUs.
You'll even see it some of MSDroid logos in the video below
still, as I haven't worked on making it pretty yet.
Once I have the part of the app that is specific to DTA
stabilised and working, I'll be contributing to MSDroid as well.
Large parts of the two apps will be the same, so I'll be
responsible for the DTA specific part, but we'll be working on
the shared bit together.
A bit more information now.
[B]What is it?[/B]
DTADroid is an app that is dedicated to the DTA S Series ECUs
that will incorporate a dash board, and the ability to log data.
It's at a very early stage of development at the moment, but,
with Trev's help today, we hacked together enough code to get
the app talking to my DTA ECU. See the brief video below.
[B]What ECUs are supported?[/B]
Currently, any DTA S Series ECUs will be supported.
E48 and P8 ECUs may be supported in the future.
[B]What connections are supported?[/B]
Connection to the ECU will be via Bluetooth and USB.
These will support the DTA RS232 stream to start with. CAN
support will also be added at a future stage.
[B]What hardware is required?[/B]
You will require a 15 pin to 9 pin serial cable as DTA use a 15
pin connection, but serial ports only have 9 pins.
You will also either require a Bluetooth dongle, or a USB to
RS232 cable.
BT is recommended, as it's not possible to charge an Android
phone when using a USB to RS232 cable.

Adapter" on ebay

[B]What's Next[/B]
Next steps are to fix the Rev counter and system voltage data
streams, as they're being read incorrectly.
Fix USB comms, as that currently doesn't support the DTA baud
rate.
Massive code tidy up. Change hacks into production ready code.
The first release will simply be a dashboard that will be
pre-configured. This will be a general release that shows a
couple of gauges, and will be used to test the code on as many
devices as possible to get the code as stable as possible. This
stage is still a couple of months away.
So stay tuned, and I'll keep this thread up to date with any
info. :thumbup:

Yup, 3 years so far by Trev.
Loads to do, but really enjoying it and looking forward to it.

I wish I knew about code like this as would love to do this to
use with my Emerald ECU! ::)

Hi Tim
Long term plans are to support more ECUs. It certainly won't
happen this year, but next year we should be in a position to
look at further ECU support.
Part of this process is to see what breaks with DTA, so we can
get an idea of what's required to support others.
So far, it's not been too bad, but at the moment we're only
creating the dashboard. Logging shouldn't be too tricky.
Modifying map settings is going to be a different story. I'm not
even sure we can support that, as I don't know if DTA/Emerald
etc would give us that information as it's all proprietary.

More development done. USB and BT working correctly, and all the
data streams are being read correctly now.

There's still quite a bit to do, but things are moving along
nicely.

Looking good Tom, something like this may have helped me find
the issue with my ECU a little quicker assuming you can read
ignition advance? ;)
