God, you are good! :-) Yep you got most of it, other than
it's a eurosport wagon with 3.31 gears.  I was surprised to 
find that there was different versions for different gear 
ratios... I rememeber hearing someplace that transmissions 
are calibrated to engines these days.  When I was at my local 
Chevy dealer, I asked what is suppose to be in there and I 
got the following. ECM's started as 1227730, then 16198262 
and then some others; I then started to get overloaded with 
the details.  I copied down off his tube, 1388ADCK, 3024ADRF, 
5486AAXN and 4456ADRF for memcals. I will go back there again
and verify this data. I have been looking for another Celebrity
with 2.8W engine without the speed density revision but I 
haven't even found a speed density equiped Celebrity yet. The
bone yards I go to have the ECM already yanked and sorted only 
by ECM number, $35 to $45 seems to be the going price in the 
yards I have visited.  I would like to try MAT version once 
and see how it feels, seat of the pants that is.  

>Was that ECM remanufactured by Delco?

I assume so since it had the typical GM stickon number and
barcode.  The one I found for my wifes 90 olds 3.3L did say
it was remanufactured by Delco, so go figure.

So, how where you able to tell me what I had?  Have a good
friend or work for mister goodwrench? ;-)

thanks
