Hey TriB,
Thanks so much for your response! Glad to hear that you’re still working on your KDS and SDS solution. It’s pretty awesome what you’ve been able to accomplish. I’m very jealous of your 4 day racetrack vacation! Stay safe!
As for the hardware vs OBDLink, since there is an option to enter the commands and reprogram the device in OBDLink on startup I’ll test that out! I had found that page long ago but didn’t realize I could use that in the app.
I would like to run my understanding of it by you though.
I assume these are the commands you were linking to:
ATZ
ELM327 v1.5
ATWM8012F1013E (set a special keep alive message)
OK
ATSH8112F1 (set a header for first negotiaton)
OK
ATFI (initialize bus)
BUS INIT: OK
ATSH8012F1 (set a header for data transaction)
OK
1A9A (Read ECU ID)
5A 9A 33 32 39 32 30 2D 30 .....
2108 (Read Data by Local ID)
61 08 0F 02 01 A0 02 02 A0 .....
82 (Close a connection)
C2
ATPC (ELM Protocl Close)
OK
If that’s the case then in RaceChrono Pro I checked and it appears that this goes in the “expert settings” menu under “Initialisation commands” which states, “Enter additional ELM327 initialisation AT commands here, separated by \n. Example: ATSP4\nATIIA13\nATIB96\ATSH8113f1\nATSW00\nATAT2”
Based on that, I assume the text that I would enter would be:
ATZ\nATWM8012F1013E\nATSH8112F1\nATFI\nATSH8012F1\n1A9A\n2108\n82\nATPC
Or do I not need to enter anything after “Set a header for data transaction”? The next few lines are “Read ECU ID” and “Read Data by Local ID” followed by “Close a connection” and “ELM Protocl Close”.
So if not, then I guess this is what I would enter?
ATZ\nATWM8012F1013E\nATSH8112F1\nATFI\nATSH8012F1
Also, once that is entered and I’ve built the cable and connected the OBDLink MX and started RaceChrono what will it give me vs what Antti and you are working on for this “Conversion interface?”.
As an extra note:
For anyone who might be reading, the link in TriB’s post to the data discussed above then links to a posters (kashima’s) schematic for the Suzuki SDS to OBD cable. That image INCORECTLY lists:
SDS MALE SUMITOMO SEALED MT 090 6P #6189-6171 (Male connector)
The actual Suzuki connector to buy is:
SDS MALE SUMITOMO SEALED MT 090 6P #6187-6561 (Male connector)
This is true for at least my bike. I have not yet received the replacement but I can confirm the first one is incorrect.
