Hi Friends

I'm trying to rewrite an EPROM M27C512 original ecu marrelli an IAQ 1G7SS.77 and I have previously erased with UV light for 20 min. Here attached an image with the error that gives me the GQ-4X. That may be happening here. Thanks for your help.

It seems the chip is not erased completely.

Do a blank check to confirm the chip is blank.

Yes. The SST27SF512 is read compatible with 27C512.
