what am i doing wrong?
i followed all the instructions, placed the jumpers and dip swich as it shows. it burns the chip like everything is ok but when i place iy in the ecu and put the key on "on" i m getting a solid cel. and when im checking tdc's it shows a solid cel. ???

ps.
checksum was removed all times.

when i'm trying the same bins on my old at29c256 everything works fine.

please help.

You need to burn 512's at an offset of x8000; the ECU is designed for 256's so it does not switch power and ground on pin 1 to flip between the upper and lower 256 kbits of memory on the chip.

Also don't forget to erase the chip every time you try to reburn, and also erase before you burn to it for the first time.

It's just a reminder...when you first start off with the burner you should have the jumper that erases the chip removed. When you click "erase" it pops the message to remind you to put the jumper back on, and then remove it again once it's done erasing.
