So to run map3 the we basically just select it and go pump e50? Or 30
With 93 you can run map 2 and 3 however it may pull boost and timing. E30 equates to around 94-96 octane so you will get better results adding in the ethanol. Correct adding higher octane just go on the jb4 mobile app and switch maps on the fly.
