I'm really interested to know how do the ECU dealer device and after market ECU devices connect to the ECU.
What communication protocol is it? Is there documentation for that?
I wonder what types of information are available - oil pressure? engine temp? etc.

I wonder if it's the same as the 'Busa?

I think the protocol is SDS (Suzuki Diagnostic System).

Here's a decent older thread that discusses the tool GW is talking about below:

Basically, if there is a sensor, its readout can be checked. The oil pressure sender is a go/no go unit rather than a measuring device so the tool won't provide oil pressure. Oil and coolant temperature is taken off the sensor that feeds the temp display so there is a reading there. The SDS system is proprietary. Suzuki will only sell it to dealers and licensed repair shops. Healtech has what they call an OBD tool that we can get. It's fun to play with but I haven't found anything I really need it for other than to figure out the TBS I had done at a dealer didn't need updating.

Great reply!
I found this as a result:
Suzuki DL650 V-Strom k7 Diagnosis Bus - ECU hacking
SDS protocol - ECU hacking
Kind of dirty low level details, but very interesting.

Thanks.
Let me share with you my thoughts - The new Glee-Strom has some nice new additions to its dash board.
I was thinking, why not retrofit a Wee-Strom with such a module that would display such information?
I'm not into a commercial product, but an open source DIY project - programming an AVR or PIC microcontroller is not that complicated.
A proprietary SDS Protocol is an issue - it may take some time to fully reverse engineer. I was hoping for a something more open.

As for healtech and the other ecueditor (GSXR), I guess they reversed engineered the protocol (perhaps not fully), to get the FI Codes.

I could mount a small computer and use it but all I'd want in addition to what Suzuki provides is a voltmeter. Gear position, voltmeter and ambient air thermometer and the only readouts I added to my bike.

Yes, I agree.
I was planning to add a microcontroller with an LCD display..I can still display these measurements.

Did you buy them off the shelf, or develop your own custom solution?

I bought them.

For gear indicator I found this cool DIY article (for Suzuki):
Gear Indicator Plans

I still need to figure what TRE is, and also where the gear voltage can be found on the v-strom (EDIT: Found it - Gear Position Sensor Connector http://www.jackphelps.com/vstrom/gipro.htm), but comparing voltage on a microcontroller is very easy, using an analog-to-digital port.
Ambient temperature is also easy - can be done analog, or using I2C protocol.
Volt meter - another A2D measurement.
The LCD display can be communicated over I2C (simple) - so the whole project shouldn't be over complex.

I currently have an Lego NXT [Robot], which has a big smart microcontroller - so I would probably use the NXT as my microcontroller at least for the prototype.
It has full support for I2C and A2D..perfect..
Also has support for motors - I could move the MadStad up and down some how.. :biggrinjester: (that's science fiction..)

I am new to this site I was wanting to know if any one has use bazzaz z-fi or power commander for there wee-strom

It's rare. Unless an engine is modified, there is little reason to do so.
