Oh that’s sore did you fix it or sell it,
there is no chance I would give up the Honda S2000 engine it’s a Japanese work of art 230 hp from a 2.0 na engine with 9000rpm red line , and vtech smile’s,

I'm guessing with the Emerald ignition that it's not running a standard map, and that the VTEC activation point has been lowered. Theres loads of mid range to be found by overlapping the rolling road maps from separate 'VTEC disabled' and 'VTEC only' runs. Set VTEC to where the graphs meet and hold on tight
