I am also looking for a Software Upgrade Unit (SUU) in order to support and upgrade my pre3000 M4, Does anyone have an SUU available for purchase from Worldwide (i.e. anywhere)?
This is the SUU i have for my M4, hope this is correct and you can see what you need for replication. Im new on this forum and Stephen is trying to help me update my ECU, and the order in which to use the SUU inline so that the ECU actually see the module. I have looked at the previews and i think if you save to your pc they should be visible, if not let me know and i will resend Regards Greg
