I recently purchased a 1227730 ECM off of eBay for my upcoming 305/TBI -> 406/LT1 Intake Swap. I was told it was not going to be supplied with a Memcal, but when I got it, it had a memcal in it. I searched over at diy-efi and I cannot find anything on it. The EPROM itself has the markings on it:

DELCO
AUJX
0982

The other piece (w/ clear gel stuff on it) has the code "4J9332" on it. I looked through the ftp site in the "bin_lib" directory and I did not see any that had the prefix "AUJX" in it. I'd really like it if this was a V8 Memcal so I wouldnt have to buy a new one.... Does anyone know what this memcal came from? I'm going to email the seller, but I figured I'd ask here just in case. Thanks!

 

You can find out what any memcal ID is from on this wite (when it comes back up). http://holman.cs.uml.edu/~sdurphey/bccfind/

You are looking for "AUJX".

 

Thanks for the info. That site is still not running, though. Does anyone else happen to know offhand what the AUJX Memcal came from?
