this the motor where they merge both the vtec-e and the regular d15b vtec into one. so from 0-3000 i believe it's in economy mode, and from 3000-6000 the first vtec kicks running in 16 valve like the d15b vtec, and secondary vtec at 6000-7200.
the only bad thing i could say is i don't have the jdm ecu to run, but it's running excellent with my regular y8 ecu.
