I am enclosing a picture of the chip in my ECM and a chip that I just purchased from a guy that swears his chip will work....I have gone to all the trouble to remove my old chip until someone beside tgis guy can tell me how to make his work..... The first pix is of a chip like the one in my car, the 2nd is his chip....... my car is a 1989 w/383, automatic.... Any help appreciated.... like my chip now what he sold me
I hope you can get your money back since your “new” chip does not appear to have the correct configuration to plug into your ECM where you removed the old one. If it does not plug into the ECM it will not work.
You have what is called a "piggy back" chip. This requires an adaptor from Moates. Read this article and it's easy to do, just be careful nit to bend any pins.
Thanks for you info......I was not informed that I had to purchase more than just the "chip".... The first one I bought from Scott Hansen was just like the old one and plugged right in....Now he is out of business and i Think I have a problem with his.
The eprom is soldered onto them memcal. No way to remove/replace without careful/professional soldering. The G1 style adapter is the way to go unless you can de-solder the eprom and add a soldered in socket.
wrong chip ?????
