Where are you getting these numbers from?

i own the 3-stage and i owned the vx for a few years...

Interesting then. Would you also propose that a y5 head would yeild similar results then?

where do you get the ECU for the 3 stage v-tec?
I've thought that getting one would be sweet as they have a higher redline, so that most likely meens better balencing, better bearings, even if I didn't get the matching ECU/wiring.

I think since he's using a chipped ecu he must be using a 2 stage ecu then having an rpm activated switch to kick in the 3rd stage.

yeah...i saw a 3-stage ecu on ebay last week for $180...
uh...no thanx...plus i would have to convert to obd2...
and then i cant edit my maps...
i'd rather sacrifice being able to use a scangauge and stay obd1

i converted the distributor connector for obd1...
but later found out any 92-95 NON-VTEC dizzy w/ blue tach wire (i think all of them) is exactly the same as the 96+ dizzy's...

the y5 is a 1.6L engine...it uses more fuel...plain and simple...
all the 96+ heads are identical as far as their casting...
even the 3-stage
the difference is in the cams & rockers only
they all use the same valves...(except the gx propane industrial motor)

i added iab control to my ecu to engage the 3rd stage
but i used the 2nd method which didn't work...
i think i need to use the first method on this page
have yet to try it
if all else fails...then rpm activated switch it will be...

You could always do the 1 wire vtec like they do with OBD0. Where the a/c clutch is used for the second gear or the automatic transmission thing. I dunno if they've cracked that code for obd1 yet. Mehbe you can turn a shift light or some other signal into the second solenoid signal.
