[Gmecm] Limp home

[jeeps2creep at mchsi.com]

Hey charles I'm still a newbie but I can run the limp home modes with the best 
of them. Now was the ecm you got from ebay for the v8 already or a 350, 305? 
If so then chances are your in like flin. Just my opinion now (newbie) and 
I'll keep this title for awhile. But the easiest way I been able to tell what 
the limp home chip will do is to go ahead and pull main eprom chip and bust it 
off, see for your self what it runs like.(seems here lately my eprom burning 
stinks so I seem to run limp a bunch) Myself, I prefer the 1637 limp chip, has 
a good over all run home about it but the 4458's run to lean (engine size 
difference) 

Well according to the crossreference sheet I found your chanced are 100%, 
looks like they kept one chip or used it in a butt load of V8 applications / 
16060837's
