Searching for 1992 Corvette Memory Calibration Chip

Hi,

I am looking for a PROM for the engine control module on my 1992 LT1 automatic corvette.  Does anyone know where I could find one?  Here are the particulars

GM Part number 1171325

68767 91 46N corresponds to where/when the car was built this was embossed on the plastic packaging of the memory module

DELCO 5224 this is the run number

DELCO BAFN3876 this is the memory type in the module.

ANy help on locating this module would be excellent!

brophonics  

cardone is a major automotive rebuilder....  in the back of their printed ECM/PCM reman catalog at the parts stores is a phone number to contact them about replacement proms and chips that they have removed from core computers they have purchased...

you might want to look at this chart also..

if you have a friend with  a mitchell..  ondemand info system.. they had prom updates listed  in there...  so you could figure out which was the newest for your exact application...

this service is not listed on their web site... so you will have to find a parts store with a printed catalog..   i would imagine that most of the people there may not even know that service exists.. and it might not any more... but its worth digging for it..

i also found this link very handy....  you might want to save it as a web page as i don't know if it will vanish someday..

i called to a friend who sold delco for decades...

there were only 4 PROMs that delco listed for that car in their info.. as final release..

16181648
16184678
16184667
16173866

the first one may not exist.. as i cannot find that exact number.. i may have written it down as he was speaking fast...

they are all obsolete ..at delco..  they were burned to order at the reno nevada distribution center... or stocked there...  they probably got ground up for the 10 cents worth of gold in them...

a decade ago... my brother attended an auction for a major music equipment manufacturer.. they built popular and sturdy equipment for professional audio recording..  at the auction.. the guy who won the bid for the warehouse full of circuit boards... was sitting next to my brother.. was saying of how much gold he was going to recover from all those chips... on those finished boards...   about 8 to 10 bucks each board...

then my brother told him that most of those circuit boards were being sold for hundreds of dollars and there is a world wide market for them.. changed the guys ideas of scrapping them..    but short sited people go for the gold...  don't see the value in the forrest of money trees in plain site...


they must have figured out that one of their sensors was full of platinum wire..  as those all went obsolete.  

Your post is pretty old, but if you are still looking, I've got a working chip from my '92 LT1 Vette.  The number embossed on the plastic is 68767 91 39N and the Delco run is 5224.  I guess the memory type (on silver tape stuck on the blue plastic cover) is DELCO BAFP 3880.  Hope this helps.
