Just posting this here because it details an update he has made to the ECU read/write software, which can now access the 512 bytes of NV ram in the ECU.
I have only used this software to read my ECU and didn't buy the licence enabling the write functions.
I suspect the NV ram contains things like rpm limits, fan activation temperatures etc....
