Hello there, I pretty much used all my atmel 29c256 chips to transfer tuned maps for customers. Now I bought a package of 10 SST 27SF512 and I'm having trouble uploading the map into it. I'm using the Pocket Programmer III USB burner. I know that before you burn a chip w/ this SST chips that i'm suppose to erase it first before I program the chip. I did that and is says that device is programmed but when I place the chip into the ecu and I get blinking light inside the S200 blue box w/c I assume the program did not took place. Please help me what do I need to do to program this chips. Thank you in advance.
