Does anyone know if there is a parameter adjustment on the AEM to allow the smog station a way to see the Vin number of the car. With the new units when they plug into the diagnostic port they will not do the test unless the Vin is visible...

thanks

No, the diagnostic port is non functional with an AEM EMS.

 

Aftermarket ECUs are almost exclusively "For Off Road Use Only" and, consequently, won't pass smog. A working ODB2 port is mandatory.
