Just about to order a Prominator and need to know what size the EPROM is.
I run a "730" ECM,S.D., from a 90-91 Iroc Camaro.
Here's a couple pic's of it just for reference.

 

Take the white sticker with the "5.7" stuff off, and look for a number like 27128 or 27256 - that's the number we need.

 

Didn't see those numbers,here's what's under there.


There's nothing under the silver sticker.

 

Just seeing that it's AUJP, it has to be a 27256.
$8D bins are 32K, so they won't fit on a smaller chip.

 

And you're going to want to put something back on top of that UV window. Leaving it exposed to light may erase it (specifically, sunlight). Though its not huge danger, its enough to warrant the simple act of placing a piece of electical tape or a label on top of it. =)

 

ya...I put the foil sticker back over it after I took the pic.
Thanks though.
