5l knock sensor

I had a few good genuine chips fail too, but I worked out it was a heat issue when soldering them directly to the memcal and heating the pins for too long. Now I solder a socket instead and never had an issue since.

There are definately fake clone chips out there though, I have had a batch... they supplied them in a chip carrier and they had put a good one in the end of the tube so the first test worked, but the rest of them were write once chips with fake markings, so you'd do a test flash and it looked ok, then any future changes wouldnt stick. Sounds like what happened here. I think most of those sellers have been called out and booted now, but surely some of those chips are still around.

Yeah it could be.
