Ok, finally my car is up and running! Long story short I shipped the unit to AEM, but they could not find any problem with it, only updated firmware. After getting it back and downloading my cal file I plugged it in, but car didn’t start, I downloaded cal again, but kept laptop connected. Car started, but as soon as I unplugged the usb cable car died again. Tried few times, but same result. I was about to ship it to AEM again, but decided to check harness connections again. Something caught my eye, some contacts inside the connector, especially pin 16 responsible for bringing 12v to the fic were wider then others. I adjusted contact blades by squeezing them closer, sprayed contact cleaner on all of the contacts, plugged connectors and car started. Few days later and everything works perfect! All it was, as for not being able to connect to laptop in the beginning, that was my bad, have to admit I was not opening cal file correctly, nerves played joke on me
All is good now, car feels fantastic as always, even maybe better after the update and better contacts everywhere
