Armand Posted November 9, 2019 Report Share Posted November 9, 2019 So switched on my g4 extreme ecu today for the first time. Software could not conect because the ecu is to old? So now im stuck with storm base maps on my red extreme. Any advice on how to get maps from the g4+ ? Looking to get a base map for the rb25det non neo. Thanx.

Adamw Posted November 9, 2019 Report Share Posted November 9, 2019 Of course you need to use the G4 software to tune a G4 ecu. There is a GTT (RB25) base map in the G4 software, it will be converted to an xtreme map when you load it into your ecu. Quote Link to comment Share on other sites More sharing options...
