Yes - See post 13 on page 1 of this thread . You can copy the encrypted mileage from the Boxster cluster and insert it in the code for the Carrera cluster. The example in post 13 is for the "old-style" clusters that were in the 97-00 cars. The process for the 01-04 cars is a little more involved. Send me a PM with your e-mail address and I'll send you the instructions.

I imagine that the folks at Palo Alto Speedometer have discovered the key to the encryption process and that allows them to insert any mileage they want in the cluster.

That would make sense. I always figured that the folks who advertise being able to do this had reverse engineered the EPROM bit.

I can do this as well if needed, but don't want a load of dodgy low mileage cars on the road
