I have two sbecs. One is a rare one from an 89 Dynasty 3.0 and the other is from a 90 Lebaron 3.0 v6. If I socket these will one or both be able to be used in my 90 Spirit 2.5 turbo car with a turbo cal?

I don't think so
Working on clearing the decks.
I don't think it will, either, but if it does, well, that opens up some windows for the 3.0!
Probably not due to the injector driver. That is the reason TBI four cylinder computers don't work with turbo engines and V6 truck computers don't work with V8 engines.
V6 should have more drivers than the 4-cyl. Might work.
id give it a go.
try to burn a 4 banger cal and slam it in and see if it runs.
that said, those with the disassembly stuff set up, (cough, cough, wowzer.....) could disassemble both a v6 and a turbo cal for the same year (like 89) and see what the IO looks like.
if there are just extra v6 stuff thats not mapped to things that the 4 cyl cals need, then i would think that it would work.
i mean, at idle, it wouldnt hurt anything to try.

I have installed it into a 2.5L TBI non-turbo. All I did was socket the ROM chip and install a ROM with the 2.5 TBI cal from another SBEC-II. All of the necessary components appear to be on the 3.0 and 3.3 V-6 SBEC-II boards. They just need the software/program, found on the Calibration chip to run them

That's what I figured. Good to have it confirmed though.
The reason I was wondering is that the sbec computers I have only control 3 sets of injectors on the 3.0 V6. The 2.5 turbo computers have 4 injector wires. I just wondered if the extra hardware driver was in the sbec one V6 computer.
The 89 CSX was the first of our 4cyl turbo cars to be sequential.
Rob Lloyd confirmed that this would work years ago. I guess it's not common knowledge because not many would think to ask the question, but it has been done.
Dont push the red button.You hear me?
Good to know.
I took a look inside both the 89 and 90 sbec computers I have and they are obviously missing some hardware. So I guess they don't have the necessary injector drives to make them work on a 4 cylinder.
