I have been looking for a while, to see if you can get the software and cable to diagnose Suzuki engines? But i can’t seem to find it anywhere, or any information out there.
I used to have one for my Audi, and it was brilliant as just used to plug laptop in and it would tell me the faults.
I got my lead from Brownspoint Marine in the USA. I think they do the software too, but it is tricky to find on their website. You need a lead, adaptor and software. pm me if you want more info I may be able to help you out with some aspects. I know what you mean about the Audi vagcom - it's fantastic. Sadly the Suzzy SDS isn't quite as good but still usefull.
