Help needed - Rover Gauge

[Plan B]

Hi all
Today tried using Rover Gauge for the first time. I'm using a USB connection emulating a serial interface out of a Windows laptop (Win 7). The RG software is seeing and configures the COM port and all appears well. When clicking the "connect" button (not connected to the car at this stage) RG seems happy and accepting the "connect" showing null values as expected as it isn't hard connected to the car. The red LED in the USB plug/logic also lights up. When I do plug into the car, no values register on the RG dashboard. I've tried disconnecting/reconnecting and closing down and re-starting the app but still nothing is reading across. Any advice/suggestions would be appreciated.

Do you have the ignition on and the immobiliser disabled? The ECU will only power up with the ignition on.

I assume you have set the correct com port in the Rovergauge options?

Yes - COM port selected and immob disarmed then engine started. Beginning to suspect the USB cable ............

Connection test for the ECU- done with the power off!

The "2.3K" measures 2.7K (ignition on) and open circuit ignition off
The "10K" measures 1K (ignition on) and 10K ignition off

Apologies - just tried it again and with ignition off:
"2.3K" was 2.7K
"10K" was 10K

sorry for the confusion
