Multiecuscan

I take it you mean the old Bravo, not the 2007-on Bravo?

If so, it looks like the engine is just not supported at the moment.
Try running a scan - if the software can talk to the engine the scan should report the ECU type - if so, see if that ECU is listed for any other vehicles, and try connecting using their settings instead.

There is a member on this forum with nick: tzok.
On his website is http://iaw-scan.sourceforge.net/ you can find free software which will work on old Fiat models like: Punto 55, Punto 60, Punto 75...
Maybe you can try it. I hope that IAW SCAN is going to helpful to you…

Older models brava 1.6 16v does support the sterym VISA Interface Euroscan. My car and I have such a program. The problem is just that the program needs the output from the computer 2 x RS 232 and runs under DOS
