emerald ecu to laptop connection

[marT350T]

Please can tell me what I am doing wrong.

Trying to connect my laptop to the ecu but cant get a connection.

My lap top only has serial com port so must be using the right one. I am connecting to the ecu vial the port that says coms on the ecu.

Any help greatly appreciated.

Which ECU are you using?? and are you using the Emerald suplied lead,

I think that is the problem. I was just using a normal serial 9 pin lead and not the emerald one.

Whats the difference ?

no I bought the car with the emerald ecu fitted and no lead
