Okay, I will just let you know what I am thinking now.
HX has roller rockers. EX has a better fuel map
Custom HX cam from Crower. EX ecu to get rid of the lean burn?

So in effect it would be a roller rockered VTEC engine......

 

How would you intend on locking those "other" 4 valves at 3500rpm or whatever if you remove the HX ECU?

VTEC is just a solienoid that turns on.....the only issue would be VTEC would the cross over would be 5500 instead of 3000.

I think. That was the dumb point in my poorly worded question. Isn't VTEC just a signal to a solenoid to turn on? If so, I could swap the ECU and get a better cam and whala......no more lean burn.
Would need the cam because the HX cam sucks right at 2900........can feel the difference (when trying) of the lobes.

 

I wasn't aware the Y5 used the same style soleniod as the traditional VTEC's use.. that being said, yea I suppose you can alter it with an AFC no problem, you also get to start off with lower CR lucky bastard

BTW I've got my old EX ECU laying around

Interesting.....wonder how a stock D16Y5 is gonna react with a EX ECU

Stay tuned to find out......ROFL
