I had the same issue connecting the laptop. I found that u have to start the AEM pro software and run it offline . Then use the ecu connect with the ignition off and wait until the AEM pro is waiting to connect. Now turn the ignition on. It connects every time now. If u get a parity error I just unplug the USB and restart the software.

Car is not starting any more with the AEM plugged in, I changed back to old injectors and went NA using only the car ECU.
I have also sent an e-mail to Kirk from HPF, maybe they can help in some way...
What do you guys recommend?
