I got my 1j running flawlessly with 3bar, it just took time tuning.
how many site's or tuning blocks does the safc give you?

Its already reading it as if it was boosting...

Sensor check - Difference of GM is it reads nearly 5 volts on the "in" line to the safc compared to the 2.xx on the stock map

Change to 2, 3, 4 and all look similar to the pic above

I was just wondering if anyone else will shsare there settings with the GM MAP on a SAFC?


Also, i hear some people saying you can raise FC on the stock MAp and that you've done 22 psi on stock map. HOW?????????? I'm htiting cut @ 14.7 on the nose

You guys sounded like this was an option.

All you have to do is wire the MAP ->AFC->ECU?

So you are controlling the MAP voltage with the AFC, then sending the signal to the ECU?
