Sockets and such
FYI, I have soldered a machined socket onto my MemCal in place of the original EPROM. It accepts chips with a moderate press fit. To swap out chips, I pull the whole MemCal, remove the lid (or hat or cover or whatever), then swap out the chips, replace the lid, and then reinstall the MemCal.
Having done this about three dozen times, now, I am beginning to worry about wear and tear on the pins in the ECM and the sockets on the MemCal.
Should I leave the MemCal installed (without it's lid) and just remove the chip from it from now on? What's the most common "system" used for swapping chips? I don't think a ZIF socket will fit under the MemCal's lid, will it?

I've never found a decent ZIF to fit under any lid. There are some that use a slide bar, instead of a lift bar, but so far they all have seemed too cheap to even use.
Might just build a ZIF memcal for when experimenting, and then use the one you already have when doing long term testing with a chip.
