ECU
ECU is a 'small case' P08 (this will run with single wire 02 as thats what VTi/VXi came with). VTEC point is at 4800-5200 rpm (4800 @ WOT), while the rev limit (fuel cut off) is at around 7350 rpm. P08 has fairly leaner maps with more timing advance then the P28/D16Z6 ecu A USDM p28 can be used longest 4-wire 02 is used and you don't mind the slight performance decrease. But no worries it can be easily chipped to P08 specs.
