- - 3 BAR MAP (https://www.homemadeturbo.com/engine-management-10/3-bar-map-5869/)

Why do none of you guys run 3 bar MAP sensor's? No need for missing link, wouldn't need an AFC. Just wondering.

why would you boost up to 38 lbs of pressure just asking

Now that's going Jan style y0!! ;)

No, REDLINE means that the scaling of the 3 bar acts as a sort of AFC hack... The EMS boys who have their EMS ---- on them (happens a lot) run 800-900cc injectors and 3 bar MAP on stock ECU to limp on. Doesn't run great, but it runs.

Problem is, it's about a -60% fuel cut. That means your ignition is even further jacked forward in the boost region than with regular AFC hack. 38-45 degrees of ignition advance under boost != fun. Further, how do you even plan on tuning the fuel?

You want to combine it with Ghettodyne or ERM NA tuner... you might have something. I haven't played with that sort of setup, but I can't see why it wouldn't work fine.
