Just to let the Porsche owners know that Porsche have been changing their choice of ECU's for a while now. We programmed a 2009 Porsche 997 C2 a couple of weeks ago and it had a SDI-3 ECU, the only way we could program this ECU was to remove it and bench flash it. All of the new ECU's now use processors.
The Porsche Cayenne 4.8TT and the Cayenne GTS use the SDI-4.
