Does anyone know who I could get to burn me a memcal/prom for a vette project Im working on? The car is basically stock with a switch from MAF to SD. Any helpo pointing me in the right direction would be great !
Thanx, Jeff, and oh yes- im willing to pay for it.

 

Why can't you use a stock SD prom to start with until you see if you need a a modified tune?

Im having trouble identifing the prom that I have. I also suspect that it may be damaged.

It has a couple different #s on it.
One on the side - 68767 31101-1
One on the top AT29C256
12PC
9523
And another on a strange looking "jumper type" of chip to the right
1R1136

I cannot find anything of use on any of these #s.

So, Im thinking about just getting a known good stock one, even then- Im not sure which # I would need.

An aftermarket or burnt one for the stock SD setup would be fine, the car has vats and vss, auto trans and 3.07 rear and I wouldnt mind stepping up a bit from the stock performance if someone has a used one.
Even making the fans come on a bit early is ok.

I will check your links. Thanx again Vetteoz.

 

Should always go back and read your posts to see if they have been updated

Thanks vetteoz, but I did look at that, and have absolutley no clue on which # out of all those 350 automatic, 3.07 gear is the right # prom chip I need.
I guess what I mean is it it the Prom bcc #, the prom code #, or the scan id #?
Which is the # that identifys the mem-cal when I go looking for 1 ???
Which # is displayed on the chip itself in case I have to go through a pile at a wreaking yard, or worse yet - ebay?

Thats where Im lost. I know what I need, just need to know how to identify it.

Thanks for your patience.

 

Any prom with the correct combo for your setup will work
Everytime the factory made any adjustment to the tune they gave the prom a new ID to identify it from previous versions

The code you are looking for is the the 4 letter BBC code
On any factory prom you are looking at the BBC code should match the prom code from the list I linked
