Try loading the base map and using the wizard to select the correct injectors

Had the same type problem check to see if your getting spark or go to Aem site for instructions on how to manually trigger each coil to see if all or part of the ignition driver circuit is bad.
Note I had spark some times and not other times might be intermittent.

Also Try checking pin c8 & C9 = crank sensor and timing ground and C20 & C21 = cam sensor and timing ground for resistance should be close to the same for both sets. Take the harness off the ems , then you'll have to look up the pins in the schematic on the aem software for your unit. If there off by a lot you may have a bad resistor that needs to be replaced or resolder.

Then Call Aem and tell them your findings if one of these tests fails. There going to have you check all sorts of stuff like this before they take the unit back for repair.

its the tune.. all jacked up... car runs fine with the stock ecu.. minus some issues... becasue of the fuel/map senser changes
