Sooo I've got a question. So when you do a Stand Alone EMS you pull the old ECU out right, I'm not sure on this. So if you pull it out and its an OBDII car and you hook the new computer up when they test it read fine? I was just sitting here and thought about it and wondering.

"stand alone" means it works without the factory ecu
"piggy back" means it used the factory ecu
obd2 systems may or may not be programmed into the new ecu.
