autogas italia powerjet lpg interface help required

Hi,
This is a plea for assistance (more for italy/european members). I am in need of an interface cable and software for a powerjet lpg system made by autogas italia or the wiring connections between the ecu and the serial com port in order that I can reset my system. UK suppliers are rare and non-responsive unless they have given training (800GBP) yet the system is probably less difficult to set up than the powercommander for my motorcycle which is supplied with software and interface lead.
If anybody can help or can buy one locally please let me know as I can pay by paypal.
Thanks
Steve
