I have the willem dual power burner and i cant figure out how to burn the AT27C256R.

i searched on hmt and here but all i can find is write ups on the 29.

thanks

 

The AT27C256R can only be burned once....

 

^yes i know.

all i have left is 2 of these chips and i need to throw the map back in my ECU. I dont need to tune with it. Tune is already done i have had the ostrich RTP but it was my friends and he needs it back so i need to put a chip back into my ECU.
