If you're tight on money here is a new afc product for cheap. http://www.honda-tech.com/zerothread?id=279803
We're still waiting on people's responses once its installed. But from the looks of things it looks like a great alternative to the fmu. Its basically a cheap afc hack. The only downside is there are only 4 variable points but people that run dsm injectors usually have the settings very close throughout the powerband. You can't fine tune as much as the e-manage or s-afc but it does the job and is much more reliable than an fmu.
