ECU Compatibility across models ? Tech advice needed.

Lets take a couple of scenarios:
The 1G-GTE engine in the GZ20 Soarer and GA70 Supra, and for the sake of this example, lets say that the ECU's for each model have a different part number.
And, the 1UZ-FE is found in the Crown, Mark II and LS400 to name but a few. Again the ECU is a different part number for each different model. Disregard separate auto computers here.
Now, take the same engine at the same period of time, across these models, so we are looking at, lets say, 1990 for example....
Would the mapping (fuel/ignition tables) be the same for the same engine, at the same period in time ? I know that the ECU would do different functions depending on the model, hence the different part numbers, but would it still drive the engine OK, thru all its operating parameters and rev range ?
Could you, for example, use a 1G-GTE Soarer ECU on a 1G-GTE Supra with no ill effects ? Or is it likely to default into limp home/run rich mode as an input from a sensor is not what it is expecting ?
I would like to know if you can effectively use a 'generic' ECU, say like one that says '4A-GZ' across all models (pins outs not withstanding) that ever came fitted with a 4A-GZE ? Or do you have to be particular about it and get the correct ECU to match the engine you have, from the original car that it came from ?
Your advice is appreciated.
Thanks.
