Calculator for XXL?

[Poche69]

On my old GO 510 I had a nice euro-Calculator that I used to calculate fuel economy when I filled up. Went back to the original site and found that the calculator could not work beyond firmware 8.5XX

Could someone point me to a thread or something that would work on an XXL 540?

Thanks again for all the help.

You may have that capability with a 3rd party application.

Also look for Event Logger at the same site
