Posted - 03/13/2006 : 16:56:56 I am having trouble reading a 27128 chip from a Nissan ECU. I have the Enhanced Willem programmer. Everytime I read the chip the data is different. Looking at certain parts of the data, some of it is correct or mostly correct and other times completely wrong. When I try to do the verify it always gives me an error quickly. I desoldered the chip out of the ECU as best I could, maybe this chip got damaged? Or am I doing something wrong? Thanks. |

Posted - 03/15/2006 : 21:39:19 The 27128 is a 28 pin DIP chip. The Vcc pin is on pin 28. So, cross the pin 28 and ZIF 32. see if this works. |
