here is info on the SPOON replacement ECU.

Sports Computer 1.6/1.8 DOHC Vtec
Spoon collated data relating to, fuel consumption, ignition timing, exhaust emissions, aging. Taking these parameters to develop a highly advanced program to achieve improved power.Extensive track tests were carried out to achieve a specification which would allow for increased output, better performance and greatly improved torque figures.Further parameters were added to have a wider range of conditions, taking into consideration new additions from the Spoon range of parts. Through this programming maximum performance would be achieved with out the need to reprogram the ECU.

basically yes , it runs richer and more ignition timing and a higher redline to benefit for "likely" bolt on parts ( CAI / header etc).
These pre-tuned ECU's are really the ultimate "bolt on" addition.
