I agree with MugenSi00. MUGEN ECU runs very rich, meant for racing and is rich as a safety measure to avoid detonation. You can get a chipped ECU (remove rev limiter etc.) and a VAFC to adjust VTEC crossover and fuel maps. Do your research before buying any ECU. You wanna tailor make it for your specific setup. I think getting an ECU before your mods would hurt you. Also dyno tuning will be the key to all your tuning. Good luck.
