I origionally posted this on the dfi/ecm board awhile ago but the traffic there is next to nill....

I want to get the prom burning underway but the previous owner swapped in another ecm and decided that he'd rip off the labeling on the ecm before he put it in so i have no idea what the ecm is and it would help to know. One of the first things is that the older versions of winALDL always had full functionality before the 8063 (88 tbi ecm) was listed as supported by winaldl. It just ran as a 7747 instead. I dont know if that means much but ill toss it in anyhow. RBob told me to post the following items:

This is from the pic below.

1) the number printed on the chip is

'23263' with a 'delco 466' below it

2) the numbers on this chip are

'185'
'16066093'
'DQ8819A'

3) finally the coding on the silver label on the bare prom are:

'AMXZ'

'0667'

Any help on this would be greatly apreciated.

 

according to tunercats caldata program its a 01227748 ecm. from a sfi 3.8 grand national. 12-01-87 thats providing the correct eprom is in it. however it looks just like a gn ecm from the pic you posted

 

and this is running my tbi'd 350? Is that possible? lol.. maybe ill start running forced induction.

 

AMXZ, according to Caldata from Tunercat is:

Model year: 1988 Release Date: 11/04/87

Hope this helps!

 

my dyslexic *** put in the bcc wrong lol.i put amzx not amxz . yeah now i get the right info lol.

 

N/P funstick. ok, that makes more sense. This guy didnt seem like the sharpest tool in the shed so i couldnt see him doing somthing crazy like that to get the stock efi back on in place of the carb.

 

Kinda like the 1227748?.
As in and not to be confused with 1227148.

 

all i can say is that at least i have enough humitliy to admit it.
