Bill,
I responded to your PM on Renntech. You are not remapping the DME for the instrument cluster coding. The instrument cluster just accesses the order type code present in the DME vehicle data section in order to know what car type it is in. In this case to look for a top light signal. On later cars with PSM it may have some bearing on PSM settings but I don't think so. I am not familiar with PSM as my car does not have it. Both the order code and trans type must be present in the DME vehicle data section before you can access the coding section of the instrument cluster to change things like wit/without AC, cruise, PSM PCM etc.
For those interested I have two good 996 instrument clusters, one that will work on pre-2001 boxsters with 19k miles (no coding problems with these), and one for 2001 and later that has 20K miles. This one also has the correct coding for the top light and is coded for AC and cruise. If you need the PSM activated I can do that as well. Contact me if you are interested.

But, I've since been wondering, what unintended effects might be encountered if the order type is changed in the DME of a car that is still, after all is said and done, a Boxster? Your car, with the Carerra engine, thinks of itself a Carrera in a Boxster's body. Standby......
I just read:

It appears that my MY03 Boxster's ME 7.8 DME is compatible with Boxsters and Carreras. So, by mapping the DME (or, remapping the instrument cluster portion) nothing will be changed to preclude the car from operating as it did before the procedure. Is this correct?
Cheers,
