Hi ! I found your website regarding communication with Suzuki ECUs.
In my case I have a Jimny 2014 in Costa Rica. I am programming my own device to get fuel consumption, and looking into PIDs as RPM, Speed, IAT and MAP. Looking into its OBD2 port, it only has GND/12V and KWP pin 7 (Kline). I had a couple standard scanners and they are not able to communicate with the ECU. My device has implemented KWP and also ISO9141 5-baud and it doesnt get any data. Reading around, I found there is this SDL protocol that Suzuki has used for a custom ECU communication. Can you help me if you have any information on how is the data message to be sent to the device? And what baud rate, init sequence, etc?
