TOYOBD1 Android data logger for 3S-GTE ST185,ST205

Postby zf_165_gt » Wed Nov 05, 2014 5:15 pm

Hi guys.
this may be old news to some but I'll make an official post here anyway.

I have designed a device that allows datalogging on OBD1 3S-GTE (st185 1992-1993) , st205.
it needs an android cell phone for the application to run. (no Apple port yet$$$$)

poor quality video showing it working

overview
http://jfbreton.blogspot.ca/2014/07/toy ... vague.html

it works on many other toyota engines too, heres the list
http://jfbreton.blogspot.ca/2014/02/toy ... gines.html

I sell them through international air mail and paypal.
35 CAD$ + shipping depending on where you are

most details can be found on my blog in various posts.

Cool project. Shame it isn't IOS. Other than the annual fee to sell in the app store, what keeps you from publishing on IOS.

How is the device hooked to the car? I'm very interested in one of these, I've got a couple old Android phones that could be repurposed for this.

CMS-GT4, Yes annual fees are stopping me, but I have no apple computer to build an application.maybe someday!

underscore, like I said earlier , most details are found on my blog
(how to connect to the car) :)

Are the st185's that different from the 165? Just curious why it wouldn't work on the older 3sgte's.

It cant work on 3s-gte before the year 1992 because there is no data stream that is coming out of the ECU. the older ecus dont not work that way, but yeah inside they use the same processor architecture so given a different program it would work.

no pc app yet, I want to have defined the final shape of the android version before starting ports to other platforms, wont be open source
I am interested to hear what people want in the future releases so some precise features may be added this way.

If you want to run this on a PC just use Cartester8000, it still does the basic job,most people fall in the usb-rs232 incompatibility nightmare or quest for a working setup when going this route, I had quite a hard time myself. that was one of the issues I wanted to get rid off when I designed OBD1READ, and taking advantage of the sleeping processing power in our pockets..

I like the temp alarm, what else can be alarmed on with this? What kind of programming is required to generate the graphics? Since this will be closed source would it be possible to have us customize the way it's displayed on screen?

underscore,
An android application is written in Java, using APIs provided through google. as for the graph mode there is no magic there, canvas and custom drawing logic. at that point it is similar to any other OS/System/Platform.

there is no other value that has an alarm since I did not taugh it usefull ,
-kock sensor detection flag might have been interesting but it seems so rare it never happened to my cars and to any logs I analyzed from people that sent some back to me,
I did not found it usefull to add an MPG calculator and a trip computer,even the graphical display at first, yet I did the graph display, mpg calculator and I am working now on the trip computer as people wanted it, so If you can convince me of something that will be usefull to many person I may be adding it next.

it may be more off an engine health analysis logic which would require a display mode for itself

- never reaching operating temperature after driving a car for a long time is a condition where it would be common sense to alert the driver that his car is showing signs of cooling defects...
- missing or misleading sensor readings: say tps,ox,spd,IDL switch,ECT, no crank sensor signal, (all those sensors would be connected yet their reading would be acceptable enough to not trigger an error code but those readings would be wildly innacurate, in such a condition you either test with a multimeter each one, or look in the application to get readings...)
-everlasting 'TE+E1' state (this is a misleading name that will be changed soon, it indicates your ecu is in self diagnostic mode,so if it is always ON your ecu suspects something wrong, even if there is no error codes stored yet, on perfect cars it goes off as soon as car speeds are rising above aprox 3 kmh)
-bad vaccum at idle (for map sensor engines), out of range VAF reading at idle for AFM engines( might require data logs from users to build something accurate for this one)
-long INJ opening duration at ( operating temperature && low engine loads )=seems like an out of spec fuel consumption ( might require data logs from users to build something accurate for this one)

I am already working on refactoring the text display mode for better use of space and readability , improving how we configure the app with less concentration.
some people would like fancy gauges instead of text values and a graph..

Any chance that a wideband might be able to link into this and that can be added to the data log?

With a new firmware + Android application build and a 5th wire pin it may be possible...
