I Almost Ruined My BMW Trying This Update :( ECU Upgrade Attempt

I debated uploading this but figured some might find it interesting.
It could also still prove to be useful for some people that want to follow along.

In this video I attempt to update my ECU to MSD81 which is an upgraded DMW for the N54 and came on late 2008 cars onward.

My car came stock with an MSD80 ECU and it has some known design flaws such as weak mosfets to drive the injectors and a weak power supply which could prove to be problematic if you have upgraded coils etc.

Unfortunately this upgrade was unsuccessful but I was really close and I hope you guys still enjoy watching.

Expect an update video soon once I have the modules back.

Thanks for watching :)
