Ecu and bsi replacement

[GiveMeABreak]

I'm not sure you will get many responses on this - as on-line coding needs PSA connection and to do that you will need your own account, to have downloaded their version of Diagbox and to have paid for access tokens to access the servers. I'm not sure anyone here is going to want to have to update their existing software (which will usually be running under a VM) to attempt this I'm afraid.

Better you take it to a dealer and have them configure it correctly for you.
