Oz is in the Argentina/Indonesia etc region. The OEM Map is 31023. I copied the tables from the latest (after vin av5457) Penner R tune for the US into your base map. Thus, you’d be using the correct base map for Oz but with Penner’s most recent tables. Note that with the OEM maps, all of the tables are the same for the R and GT across regions. You will be fine with Penner’s US R tables.If Australia is in the Argentina/Indonesia/S Africa, then wouldn't your US map not be suitable for me?
Also in the picture i attached do you think there is a typo (in red) in the 31018 map warning. It sounds like it shouldn't be used in any region. Or are there more regions?
