The ECU is here. It looks like this under the dash in my car. No, there is not enough room to get this thing in/out of there.
On the donor car with standard transmission, I got out even the brackets mounted on the ECU. For my car, I had to disassemble the bracket for the relay module, and reassemble it as a 3-piece puzzle, inside the dash. Boo. The final bolt was set with about a foot of extensions and a swivel, because my hand+wrench combination would NOT fit.

And finally, this is why you should vacuum your floorboards and remove all bolts, tools, etc, from the footwell, BEFORE you decide to replace your ECM.

I revise my assessment. After fixing my exhaust leak by replacing the exh. manifold, and doing some A-B-A-B testing.
The power boost is about the same as when you turn off the air conditioner: noticeable but not extreme. My engine runs a little rougher with the 1.8L ECU also, but it took going back/forth to notice it and it's not a big deal

There's no such thing as a Rev B. It's either Rev A, or not.
As for your other questions, they are answered in this thread.

Just something I thought I should add, I have a 1.8 ecu (39110-23940, the recommended one) in my 00 Tiburon. The speed limiter is lower than the stock ecu, that is, if the stock one has a speed limiter. Max for my 1.8 is 110MPH. Has anybody else noticed this with their ecu?

From what i know, the 2.0 doesn't have a speed limiter. It has a rev limiter at 7000 i think, and max speed is limited by gearing: 7000rpm in 5th gear = 125mph or close.
Are you saying that after changing the ECU to 1.8 you can't get past 110MPH? Perhaps the 2.0l needs more fuel than the 1.8 ecu will provide at that load and rpm? (just a thought)
