Going through some stuff yesterday I found that I still have a couple of spare 4.9l EPROMs.
These are for the Caddy 4.9l swap wired as a 91 Deville (as per my wiring thread). They have had all the changes done to them to eliminate any error codes and the VATS (passkey) protection.
For a manual transmission car. Speedo was set up for the stock 215 tires, but that doesn't matter too much if you don't mind your speedo being out a bit if you have different tires sizes.
One has Stickpony's programming with the modified fuel maps.
The other has Rockcrawl's code - original collectable item.
$70 shipped for either
