My used Falco came with aftermarket cans. How can I tell if I have an aftermarket chip?
Most chips are copy-protected. Open the ECU and have a look. If the chip sits on a tiny daughterboard, its an aftermarket chip. The stock chip is seated directly in the socket on the motherboard. The stock chip is also quite plain in its markings. Most just had a sticker with a few digits of code on it. Most aftermarket chip manufacturers but some sort of advertisement sticker on their chips.
