Hondata's K-Pro ecu is needed.
K-Series Programmable ECU
Trust me, it is absolutely THE best tuning solution for the K-series, and even on other Honda's as well. You can see Kpro being implemented in other applications such as the Element, s2k, D-series civic, TSX, Accord, etc.
It can disable multiplexor controls and prevent a CEL from coming on on your swap. It can get you to pass OBD2 inspections even if u're not "compliant". Huge tunability, safety nets, etc etc. Tuning is KEY to the success of your K in anything you do. Whether it be staying stock, boost, or N/A. Kpro will be the heart and brain of it all.
