Kick ass. the Emanage of course is not a piggy back. I have myself completely gotten rid of the MAP sensor adjustment with the emanage. I ran into way too many funky behaviors in my car when the emanage was even zero'ed out on the MAP adjustment. Bad Idle, check engine lights, etc.

I now am configuring my car to use the 8-injector setup with stock injectors (so no MAP sensor adjustments).

I am using the additional injector map on the emanage to add fuel to my car (which controls the main injectors) but also control adding fuel to the 4 additional injectors (yes, you can control 4 additional injectors in the emanage without buying the AIC).

Think about this when you want to know what the emanage can do:

-To remove (lean) fuel, you use the MAP table
-To add fuel, you use the additional injector table
-To change ignition, you use the ignition table (and you are right, no one that i know has implemented this yet for our cars)
-To control 2 channels of injectors (and with the right resistors, each channel can control 2 injector each - 4 total), you use the extra injector table
-To use boost as an axis for any of the maps above, you use the 3-bar map sensor

HOpe this helps. The GUI and 256 point map tables kick ass.
