"To start things off you can see that in order to be able to communicate, read, edit and upload the data on the
SIEMENS SDI3 requires a lot of precise and rather nifty gear. The Bosch Motronic ECUs of old were far more cooperative that's for sure. As of now there are no tools available specific to this new ECU. EVO had to engineer and manufacture their own to "open the communication door" into this ECU. Also, this ECU does not use the same shape bosch type map structure. It uses the same map structure as the SDI4 ECU found in the Cayenne TTFSI which we have learned about a year ago through trial and error. This made us VERY familiar with the maps in the SDI3 found in the 997. Once the ECU has been what's known as "boot-strapped" (this is tricky indeed) we gain access to stock data and "read" it out as shown here."

"Hey fellas, just a quick note to let you know that the EVOMSit software (which we ran so successfully on our 06 Cayman S etc...) is now available for the DFI 2009 based Caymans using
the new SDI3 ECU."
