I know that most people use Innovate for the EU's A/F target function, but can I also use the Zeitronix one? Thanks in advance

 

I don't see why not. You just have to tap into the wideband wire. I was using my AEM for the dataloging feature with the EU. You just need to buy a 2nd boost pressure sensor harness to connect to your wideband.

 

How exactly do you use the Target A/F? I made a tree and setup the parameters but not really sure how to implement it. I have the injector map chosen also
