For security purposes and to deter people from copying, modifying, etc. their code, they solder an EMCS module to the ECM board. It's actually more than a chip; it's an actual processor. Anyway, while it may be a better, more secure solution for them from a prying eyes standpoint, it's much less reliable than simply flashing the ECM (software only, no hardware changes are made). So what typically happens is over time from driving and NVH, one of the pads on the board loses contact with the chip and renders the car inoperable. Sometimes it can be repaired, other times it cannot. In the event that it can be repaired, it's usually a "band aid" fix and it winds up happening again much sooner than the first time. This is why flashing the ECM is a much better and reliable way to go. Hope this helps.
no you trying to sell your tune doesn't help at all.
