VRIS
-
Remember on a ZE the VRIS are supposed to open all the time, not just at full thottle, as in the DE engines.
Another point, if you get a big kick on a DE engine at 4500, it's sometimes due to VRIS 1 being duff and only VRIS 2 working, there should be a slight increase, but a BIG one is usually due to the first solenoid not operating.

with one is first and second the litle one on the side and big one in the middle witch opens first ?
and do they open if revs are slowly taken up when operateing it by the throtle body so you can see them ?

I wouldnt do it using the TB.
Put a bit of paper in the 'end stop' (closed position) and go for a drive, if the paper is still there, they didnt open.

kl31 and kl36 have the same affect on the klze - they have the incorrect vris points… the best option is to get a chip from probinator to modify a k8 ecu - this is the best option hands down.
also what intake are you using? stock k8 or curved neck?
-
Mooneggs dont think thats right. the KLZE comes with 3 diff type of intake manifolds.
-
The Millina circular manifold (with the V6 24 Valve sticked)with the cuved neck to the trottle body. Thats works well with the chipped MX3 K8 ECU. VRIS points match up.
-
The MX6 Flat manifold with the curved neck to the Trottle body.
Thats works well with the chipped MX3 K8 ECU. VRIS points match up. -
The MX6 Flat manifold(with the V6 24 Valve sticked) with the straight neck works best with the KL36or KL31 ECU(jap ECU only). THe VRIS points match up here.
It's so so so important you know what type of engine u have. If you dont match the right engine to the right ECU your not going to get VRIS points, so no semi supercharging, no 200BHP

-
Using the KL31 ECU, with the JDM KLZE… this is the inlet i have think its the MX6 one.
-
ya thats the manifold im after too. getting it soon, very soon.
does the KL31 ecu match the VRIS points?
I thought the only diff between the kl36 and kl31 ecu from the import mx3 was that kl31 only did manual transmittions and the kl36 did both manual and automatic?
-
@a4c7f81ae2=MDM_MX3:
does the KL31 ecu match the VRIS points?
I think so, doesn't feel as much as a kick as the K8 did when the VRIS comes in but feels alot longer and smoother power band. Got to get it on a riolling road really to see.

stupid question here what is vris???
-
Na man not stupid at all.
Mazda mad a manifold with an idea in mind. this idea was to use the different lengths of runners(the part of the intake going into a particual section of the engine) as a way to resenate the air to produce high pressure, dense pockets or waves(occilations) of air to flow into the cyclinder producing a mild supercharging effect at certain RPM ranges.
The long discription that mechanic posted explaines it very well.The natural physics behind it is that every object including living ibjects have a natural fequency. when this certain fequency is produced by a speaker or source it causes the atoms(that make up that particular object) to vibrate. this is called resonance.
now in physics if you can vibrate air, (resonate air), you cause a build up of pressure as these atoms are bouncing around like made trying to vibrate more and more. as they do this in an enclosed area(the runners of the intake manifold) pressure builds up and hense causes the same affect as a supper charger of a car.
Higher intake air pressure into the cyclinder= more fuel required to burn all air = more power.
the flute effect explained in the previous page is discribing how two actuators open different ports in the intake manifold causing a difference in fequency. go ahead if u have the V6 MX3 and pull the trottle cable whild the engine in running. you'll see one actuator open first then the second at the higher rpm.
Its just to keep this effect when doing an engine chance you need the right computer(ECU) to tell the actuator to open on the right RPM as different length of intake manifoldhave different harmonics.
And Hormonics are for a different day lol.
Long peice…....i need money to pay more attention to my car lol.
Hope it helps

would that explain the flat spot at 4300 rpm??? oh and ya can have those bumpers mate!
