Thanks Steve - not being defensive - just pointing out that it's not that using the OP2 and Ecuflash is somehow inherently more dangerous (which unfortunately is the perception) - just that it takes a deeper understanding of the process.

@Andrew025 - there are two ways - the easiest is to identify which actual rom the v2.061 maps are using for your region (which I believe is D00C), then to flash the D00C stock rom onto your ecu using ecuflash, and then to flash the OFT rom - since the definitions will then align. In other words - the process would be to update the stock rom to the latest version for the region (which is what the OFT will be using), and then to upload the OFT map.

Otherwise, a more roundabout way would be to identify the latest rom the OFT is using (D00C), download the appropriate Ecuflash definition (D00C) and then edit the Ecuflash xml the following way:

- change name to ZA1JA01C
- in the xml change the xmlidto ZA1JA01C
- in the xml change the internalidstringto ZA1JA01C

i.e. <romid>
<xmlid>ZA1JA01C</xmlid>
<internalidaddress>8000</internalidaddress>
<internalidstring>ZA1JA01C</internalidstring>

I think what I must do one of these days is create a separate branch on Github that caters for the OFT roms specifically.
