Ken is right, I just did this last weekend.
First I ttok some of that heavy blue masking tape and placed several layers of that around the emblem to protect the paint. I put about 4 layers all the way around the emblem so you could not see the painted surface.
Then I used a plastic decal spreader, (like a plastic putty knife) to work under the emblem all the way around patiently and slowly working it a little at a time further under the emblem. The double stick tape will seperate and ultimately you will have broke the emblem free from the body where the tape hold it.
Then there are 2 plastic pins holding the emblem in place with clips on the underside of the body panel. Without removing the front bumper, you will not be able to get to the fasteners that secure the emblem. I used the plastic spreader to lift the emblem and then used a fine tooth small hacksaw blade and slipped it under the emblem and it took maybe 4 swipes to cut the pins, they are soft plastic, like the emblem. Once that was done the emblem came right off.
I then took a nice fine polish and cleaned the area of all residual two-sided tape and in my case, installed one of the red Acura emblems to match my red car. IMO it looks very clean.
Good luck.
