I'm interested in coding a battery capacity change and learning how to do a little more.
Definitely don't want to delve into INPA etc so I'm thinking Rheingold ISTA+ is the way to go. These are really novice questions so please forgive me.
Is Rheingold standalone? Somewhere I got the impression it needs EDIABAS to run.

Does all other software such as MS Excel, Word, etc need to be off the machine to run Rheingold?

I see the software downloads priced anywhere from $11 to $112 to free (which scares me). What to look for if I decide to buy?

Maybe I should be asking all of this in the Coding Section on the E90 board, but, thought I'd try here first.
