Oz,
That's a great thread. In fact it is still work in process. I will monitor it and see if they reach a final solution/package.
In fact they are looking for something far more ambitious than I am: diagnosing all the car systems.
On my side I would be happy with a low cost scanner that could use the 38>16 unterface without compromising too much its functionality.
On the other hand, depending on the final cost, the solution they propose may be VERY attractive.
In the meantime I did some more research on OBDI / OBDII compatible scanners. No luck. They exist but work on OBDI only for a discrete set of brands. (mostly the three big in the US)
Thanks, Jorge
