VAFC 2 and ECU issues
Ok a little background. When i first installed the piggyback a month or so ago this problem occured, then went away. I had the battery disconnected for roughly 6-8 hours. Hooked the piggyback up properly. Heres the problem, when i woudl start the car it would start fine, then immediately die, unless i gave it some gas. This happened for a few days then went away.
Again, i had the battery disconnected over the weekend. I was putting on new gaskets for my headers cuz i had a leak. It started up fine, i drove around some and then turned the car off to get some gas. When i started it up, it happened again. The car will not idle without me giving it gas. I have the stock ECU. Does anybody know what the ECU is doing during this re-learning process to make the car die like it is? All functions/guages of the unit seem to be working fine.

SES codes were P0300 - multiple random misfires and P0327 - knock sensor circuit low voltage. Lol the exact same codes as last week. Dealership just replaced a coilpack and 4 spark plugs. Time to go back...
