Possible Solution

According to Mugen Products at R & D Motorsports the Mugen chip is not a chip, it is a replacement ECU. So it will only fit cars that have a configurable OBDII harness (I'm pretty sure). It claims "This ECU has specially mapped fuel mixture and ignition timing. 9000RPM rev limit and 6000RPM VTEC engagement. OBD2 sensors are eliminated. For racing use only." But it comes with a hefty price of $1500. As for the Spoon ECU, I couldn't find anything for you. Possible enhancements to get the extra 15HP are some simple bolts ons like a cold air intake, headers, cat-back exhaust, and possibly some more elaborate modifications like a turbo or supercharger.
