Default Flash Only to JB4 - 11-11-2021, 09:53 AM

Hi All,

Had a JB4 G5 ISO previously installed but decided to take off and go the flash only route.(I have Hybrid Turbos (17Ts) FBO and N20 3.5 Map Sensor now)

All OK but miss the functionality of the JB4 so wish to reinstall it.

Would the current flash work as a BEF once JB4 is back installed? Just set to 4/2 on the settings and away we go?

If yes - (hoping this is the case)

The map I have has the 3.5 TMAP dialed in as such. So would i be right in thinking just leave the JB4 setting to 0 or would i still need to change that to 1 (3.5MAP Installed) even though its already been dialed in to my flash?

Hope this helps and someone can help us answer this!
