[Gmecm] LT1 in G-Body

[Rick McLeod]

Tim,

I got involved in sorting out a wrecking?yard abortion for a friend,?it was a 
hybrid of parts from both vintages, and even though the systems are 'similar', 
there are some subtle differences in the harness IIRC that drove us crazy so pay 
attention to schematics if you swap the ECM on a donor engine 


sorry I don't remember more, I just remember it was one of my worst nightmares 
and was never so glad to see it go down the road?(running) w/ a happy new owner 
never to be seen in our garage again

there are replacemnt ECM's for yours to be had, they just get pricey

as for how it drives?w/ a engine from a lighter car in a heavier vehicle, it 
will likely be just fine stock unless you're doing work to the engine 
mechanically, then tuning will most likely be needed to make use of the new 
parts. To this point, one of my projects was a '89 L98 IROC TPI 5.7L into an XJ6 
Jag, wow what a wake up call for that kitty! you'll enjoy the new found 
drivability from the FI, throttle response improvements, economy, etc, 


good luck
?
-rick

It will probably run fairly well.? I would be more afraid of the ECM.? If I 
remember correctly, it was only used two years in the vette, and one year in the 
F-body. If it ever dies, you may not be able to replace it.? It might be better 
to install a 94-95 ECM right off the bat.

?Hey fellas . I see a lot of threads on lately about tuning. I'd like to 
interject a question. I am working on a transplant. A 93 LT1 into a Monte 
CarloSS. ?While there is a lot of activity here I thought I might get the best 
answer. Will I need to do any tuning to have good drivability and performance, 
will the weight difference in the cars create a need to tune differently. ?? ? 
?Thanks. ?Tim
