rs tunere remap question

[Adey.]

hi all, i have an rs tuner pro and have gone to the group n map for my software, question is can i go to a late spec softwear? i know you can go from say 6200 to 6500 but mine is the a300? will this make a difference? or because i have the vin number cb0m can i oly use softwear for that vin-ecu? cheers for the help

Then you should be looking in the CB0M/CB1C section.
There you can find the A300 software version you need.

Cheers for that, guess it means i cant change it then.
