Jack that link while having some spelling errors (something I know quite well!) had awsome info... I think I now will use the SOHC VTEC-E 3 Stage D15B.. It has 2 VTEC actuator pins for three stages.
Stage 1 great gas less power 2500RPM or less
Stage 2 moderate gas and moderate power 2500-6000RPM
Stage 3 Power only 6000RPM and above
I am sure the listed rpm ranges are subject to debate and would depend on gearing and how the VTEC was tuned.. HONDATA!!
What kind of ECU would you use with these economy VTEC's? Any ideas?
