FIAT Multipla BiPower (CNG) Engine ECU not responding

[rally]

Hi (it's my first time),
My FIAT can't to talk to this software when I try to connect to Engine ECU. No connection. Other systems - ABS, Airbag works OK. I'm using KKL cable.
When I use other software (www.automex.pl) then is OK. But that software is only standard OBD II.
In past version (2.5) I connected to engine ECU by Fiat Bravo (engine 1.6 16V, ecu 4EF). Now it's not working.
If you have any ideas how to connect then let me know how to do it.
PS. I try to connect if the button petrol/CNG was on and off
cable is OK, works fine with my other car ALFA 156 Selespeed on all systems.

Regards
Rally

I had the same problems:
I can´t connect to the ecu with the kkl Interface:
It does work fine with an elm Interface not with the kkl : connect to Multipla 1.6 V 16 V ecu not only to the bipower ecu for more details

I had the same. VAG KKL doesn't work at all. ELM working only with Magneti Marelli 1,6 16 V, not with Metatron.
