How do I remove the Motronic board from the casing?

Post by JoeyG85Z »

I bent a pin on my newly upgraded 4.4 ECU and despite having bent it back, I no longer have 5 volt reference to several sensors. I figure there's a broken trace on the underside of the board which I could fix, but I can't figure out how to remove it from the case. I already have the shell off, but I need need the board off fully.
