Punto evo elm 327 to ecu connection failed

[fabrice59]

Hello,

I have a 01/2011 Fiat punto evo 1.3 multijet 95 and using elm 3.27 interface 1.4 iDiagnostics "designed for italian cars"
I using registered software for one year now and all works fine.
But now When I test interface they are all ok but note latency too high
When I read available modules on punto evo 1.3 multijet it identifies the engine ecu,body computer and dashboard computer but when I try to connect to engine ecu..I get the red box "connection elm 327 to ecu failure"
I have installed multiecuscan on my second laptop (win vista) but same thing.


Help me please !

Thanks
