Think you mis-read that, the 2.8 ECU will keep up with a 3.4L.  Maybe not 
clear, you stick a 2.8L electronics* on a 3.4L engine without tuning it 
"should" run well.

*2.8L electronics = MAF not speed density.

btw, I used to own a 2.8L powered 87 camaro.  had all the power a young kid 
should have, enough to get sideways going around corners, chirp the tires at 
the 1-2 shift or 2-1 downshift for acceleration (700r4 automatic).  beating 
the hell out of it, it'd still get 22 mpg.  Sold it to a friend about 6 
years ago, he got 36mpg highway with it.   Still have the original engine 
(long story) and a set of front wheel drive heads that I intend to put on it 
one day.  Using some numbers I found on the net a few years back it should 
be somewhere in the 14.5-15:1 compression range.  Don't have the time, money 
or a vehicle to put such and engine in so it will have to wait.  I'm also 
pretty sure the engine will end up scattering itself with the cast 
internals.

 Although I have heard a stock 2.8 ecu
