Syvecs with E6x N54

I was under the impression we could use ECU's between platforms (ie. E90 can use a E60 ecu)... if this is untrue this will end quickly.

I wrote Syvecs and they said their ECU won't work with an E6x platform and I would love to hear everyone's thoughts. Does anyone know if you can control X-Drive with Syvecs on the 335 X-Drive cars?

Thank you for your time and help!

Im just guessing here but I think the standard roms all contain enough data to be used with all N54s. but the syvecs was made from scratch for a 3 series n54 and so doesn’t have it.
This doesnt mean it cant be done, it may not have been done yet....

To clarify a couple things. Syvecs can control anything you can calibrate. The reason the n54 pnp kit won't work in other platforms is there is a fair amount of CAN data to control some functions. It wouldn't match other chassis. You could use it as a starting point, but you'd still have your work cut out for you. Also, there are no "roms", it's a purpose built database.
