If you are the extractors that I think, that the sort of punches that screw on the ecu and then pull it on, would not have helped in my case. There was so much silicone that lifting the lid is stuck and it's coming on along the tab.When I noticed it was about 3-5mm in the corner, and I detached. That was the only problem during the whole operation. The two screwdrivers were well away from the circuit always.I don't know what to think..I can't find a diagram or photo (best) of both sides x check if there are all the components. I tried to solder a resistor 220 ohm and then a capacitor of 100 nF where I suspected the lack of it, but it did not work. In one case the engine was not to be even more in motion.
