Dual Boost Stages/ Safc 2

[ARETHT3]

hi all

just wondering what to do when i get my new turbo installed... i want to run daul boost eg 10low and 16 high so i figure i will need a dual stage boost controller. Is this possible with an SAfC 2 as im guessing i will need to get two different fuel/ air maps enterned. How exaclty does it work. wWll i have to change the settings on the boost controller and the safc when i want to switch between the two or will the safc automatically deteect and change.

cheers guys any help is appreciated

Don't need 2 different a/f maps, just make sure the SAFC is not leaning out at 16psi, it will be fine for any psi lower.

Though I'll add something though, not a great idea to be doing 16psi on a stock ecu, it's possible even with the SAFC doing the correct mixtures up to 16psi, the stock ecu it might trigger fuel cuts or going into rich and retard mode etc

so you saying that the safc will be able to handle the difference in boost on the same tune

yes that's what he's saying, get the safc tuned running 16psi & it will be safe to run under that such as 10psi on the same tune.
