By the way - which DME version do you use?

5.5.2 99

I sent my DME/IMMOB/FOB to EcuDoctors -- they tested the setup and it worked fine.
I then had them modify the DME to be stand-alone.

My symptoms have not changed since I got it back. So as best I know the DME is fine and should be working in standalone mode.

So assuming the DME is working fine and the Immobilizer setup is happy -- what signals could prevent the DME from allowing the car to start?

I need to probe each one and see which is the cause?

I'm about this close to buying a second (cheap) Boxster just to have a known good unit to probe for signals on the DME.

thanks,

Mike
