I received my AEM EMS back from aem and they fixed the ignition driver board on the unit.
Tested it last night and the car fired up with no problem.

Now its time to go to IP to get it tuned.

Update I had the car tuned on monday and we had some issues with the startup after the car got hot durning the dyno runs. Brain at Ip had to keep cranking the car to finally get it to start up each time. He checked spark and it would spark most of the time.
At first we thought it might be a bad main relay.

The past few days the car has gotten worse at the start of the week I could start the car up on the first or 2nd start and it would Idle and run with no problem. Then the next day or two It started having issues restarting hot or cold and the idle would just drop and stall out when I was slowing down and stepping off the gas pedal.

Through the process I rechecked all my grounds and battery cables and had the brand new optima battery checked as well. Checked for voltage from the alternator too because the car seemed to turn over weak when cranking. Picked up a starter too cause we thought that might be the issue, but after checking the car some more today we tested for spark with the aem and didn't get any. Put in the old ecu and it cranked right up three times in a row with no problem. Then went back to the AEM and nothing.

Looks like I will have to send the unit back to AEM again.
