If I'm not mistaken, VRIS is very noticable when it kicks in at 5000rpm right? I have a KL-ZE w/ all the fixins named in the quote below, but I don't feel that extra kick in the pants at 5000rpm. The only thing I can think of is that I'm still using the J-spec ECU.

The mechanic said that it would only give me an extra 5hp. Does anyone have any experience with both?

Are the VRIS opening at all? With either the Aspec ECU or Jspec they should still open. Perhaps one is broken

How would I be able to tell if they're opening? Is it that little instant kick at high rpm? Cause I had that with my KL-03.

Look up "paper test"

There are two solenoids that activates the Vris and if it fails than your VRIS isn't working at all.

use aspec ecu to do the test!!!!!!!!1

here a way to pull the code yourself, i was doing this today but the thing is the jspec ecu w/ the je50 does NOT give any code. therefore, u will have to reinstall the the aspec ecu along w/ your original maf to pull the codes.

as expected i pull all the egr related codes such as 16, 26, 28, 29 and since i have a 93 i also pulled a 69 code which is the ectf.

this should help u a lot.

what you do.

Screw the paper test. I've actually mentioned this one before.

Start the car to charge the vac chambers. turn it off.

With the ignition off, short the TEN and GND pins in the diagnostic box. Watch the two actuators and turn the key to on (not start). the actuators will momentarily flick open then closed as the ECU performs its discrete output tests (all output functions of the ECU are tested for open/short during the three or so seconds before codes start to flash). It may help if you have someone else turn the ignition on without going to start whilst you watch the actuators.

The KLZE does provide the same codes.

Paper test is for loosers:D just kidding.

If they don't move, there is something wrong. Either broken vac chamber, check valve or stuffed solenoid. If one works and the other doesn't, swap connectors to see if the fault moves. if it doesn't, it's the solenoid, if it does it's the wiring or ECU. All common sence.

So long and thanks for all the fish.

Thanks guys,

Now all I have to do is find out what a paper test, and a solenoid is then I'm set! :p

so you are using the J-spec manifold and the J-spec ECU..
then you wont feel the "kick" as the power doesn’t start a 5000rpms on a properly set up KLZE. It is there from go to woe
IMO, there is nothing wrong.. :tup:

Nah man, the powerband of a KLZE is similar to the KL-03 except that you get most of your power in the high RPMs (6000). I'm still using the Aspec ECU, but from what I hear it won't make too much of a difference whether or not I use the Aspec or Jspec ECU. I think parisifal is right about the solenoids. I'll find out next week!

So you are using the wrong manifold for your ecu…

So what you're saying is that to open up VRIS, I'll need a J-spec ECU since I'm using a KLZE?

FYI my old KL-03's VRIS was opening up with my Aspec ECU.

Obviously the A spec ECU will operate either the KLDE VIRS as easily as the KLZE..
The difference is the actual chambers are of different lengths and design in both cases. And as such should be opened at different times in the rev range..
You could also get a VRTuner and run a standalone VIRS controller .. apparently the boys at VTR clame it workes better than the J-spec Ecu, as it is completely programmable..
