SDS interface


   This is a little bit off topic for this site but since hacking ecu's might have an effect on some of the parameters set using the SDS I thought I would throw it out anyway.
    Has anyone seen the new SDS which is needed to do simple things like set the idle speed and maybe the TPS (setting the TPS changes the idle speed). Suzuki charge $600 for the box and $120 for the diagnostic program. BUT dealers are saying they are for dealer use only and refusing to sell to the general public.
    Since the very clever people on this site have found you can completely reprogram the the ECU with little more then a TTL-232 converter I was thinking maybe the SDS would be easy to replicate.  Software might be a little harder.........

   Oh and since the Bandit is Suzuki's best selling bike and the new versions are FI, how about a hack for them! I don't see many ECU's on E-bay though or I'd happily buy one and take a look inside. Then send it to someone who actually knows what he is doing!!!confused

    I read the thread about going commercial and feel real sorry for you guys that are working so hard to get the secrets out to all of us. Only to find someone is selling this on to others. Just last week a friend of mine in Florida was told he could have his rev limit raised for $150. It would be nice if say 10% found it's way back to some of the original brains behind all this. But I don't see how this could happen.  Anyway hope all this talk about money doesn't doesn't put you off.

If you get the software/maps downloaded out of the ECU it would be no big deal to reverse engineer the SDS protocol and then write your own PC software.

If it is anything like the Busa or GSXR then hardware wise it should just be a simple TTL serial interface. If its newer it might be a CAN interface. Either way it would not cost anything near $600 to make one.

The numbers on my '08 Bandit 1250 Denso ECU show:
32920-18H20
112100-5760

It uses a 26 and 34 pin JAE connector, but the 34 pin wiring is different from say an 05/06 Gsxr. For instance, 7 and 24 are serial in/out on the GSXR but they are unwired at the connector of my GSF1250.
The SDS cable connects to the dealer plug under the right cover of the bike, and the 4 wires on that connector are colored:

white/red (which matches the wire color on "Pin 56" of the ECU) That's actually on the 26 pin connector, pin 22). It's unlabeled for function in service manual.
Orange/white (Matches pin 17 wire on ECU - Power)
Black/white (Matches multiple wires on ECU - Ground)
Gray (Matches pin 32 on ECU) Serv. Manual calls this pin "Serial Data for self-diagnosis"

The white/red wire gets grounded to put the bike in "dealer mode", which shows stored error codes on the bike's guages. I wonder how the SDS manages the few resets it actually does?. The only wire we have left is the gray wire for serial, could it be bi-directional? Or, is it possible the white/red leg makes the ECU change modes when grounded, but acts as an Rx otherwise?

Can anyone offer any additional thoughts on this? I'm totally new at this as you can probably tell...

Just read a post on the Gsxr 1k 05/06 by RR. I'm reading the two serial lines there are in the SDS connector and are colored white and green. The colors on my SDS connector are White/red and Green, and that's close enough for me to ASSume the white/red is serial out and the green is serial in. The other two pins on the SDS connector should be power and ground I suppose.

On the bandit when you hold the serial out to ground the ECU jumps into dealer mode. Does this also happen on the Busa or Gsxr?

All of the unlabeled (in the serv. manual) wires to the ECU appear to go to the Yosh connector, ground, and one is the white/red Serial out. There are still 6 other pins on the 34p connector which are unwired and unlabeled. Now I need to figure out which is which...

On the Maximum-Suzuki website a poster has got an SDS box and will be doing some research on how the box connects and what data flows through the wires.
It is nearly winter time (we have frost on the ground this morning where I live in the UK) so lots of people will be more interested in mods and hacks then riding bikes....

On a different note, I did find that we have 2 devices at work (P&E Cyclone Max) for loading software into our products using the BDM port. So it looks like I might have all the tools to get the base maps out, once I get hold of an ECU..

On the Busa you can rewire the Yosh box connector and use that for flashing....if we need to use the Yosh box connector for the SDS we will need another way to connect.

The pinning of the SDS-connector on my GSX-R 1000 K6 is:

SDS Funktion ECU-Pin
B/W Ground 34
Gr Serial Data 32
Dgr RxD1 24
W/R Test Switch 56
W TxD1 7
O/G +12V 17

Hope that helps

Additionally the manual calls the box K-line box sounding SDS box being an OBD like interface.

Any other news on this topic ?

Something along the lines of this maybe ...

Those Txd1 and Rxd1 - are those the same as programming pins for gixxer ? It would make sense that also ecu updates can be done using the same connector ...

SDS Funktion ECU-Pin
B/W Ground 34
Gr Serial Data 32
Dgr RxD1 24
W/R Test Switch 56
W TxD1 7
O/G +12V 17

Hans just confirmed over email that the Rxd1 and Txd1 are the programming pins. In Busa ecu code the Rxd1/Txd1 are not used by ecu for anything else than programmin. Instead the Txd4/Rxd4 seems to have some kind of interface protocol.

Therefore the first bet goes into assuming that Gr Serial Data is connected to single wire K-Line interface and txd/rxd can be used for flashing the chip - just a hunch that may proven to be wrong.

Funny, I just sent you an email regarding the MC33290 and now I saw you posted to the same theme....biggrin

We're finally making progress with the SDS.

In the current version of ecueditor the SDS protocol is partially implemented as engine data screen.
