So I started messing with tephra last night and I'm just wondering when I copy my maps to the tephra maps how does the ecu know to use the big maps. ?
Because the small maps are still there in my image rom if I scroll down to fuel maps and the ignition timing maps I know this might sound dumb I was just wondering

 

No answer anyone please just wondering while I start working on my speed density tune

 

V7 uses bigmaps, the small maps will still be in there, but just not used
