Variable silencing system I think it stands for.

It's a system to restrict the amount of air through the exhaust to quieten the car for silent mode. Might want to check if the valve is actually stuck or not as due to being in the exhaust they tend to get stuck in one position a lot.

Since my exhaust is still looked as something stock (I'm not sure about this actually), I'm going to test it soon (I've done it before but I didn't realize somethin' different).. By the way, is it a standard feature for this type of skyline? Thanks! :)

I think you're right, NJR 34GTT.. So it should give a significant change to the sound?? :( One member of skylineowners.com in UK also said that it is common for this optional system to be got stuck.. I will investigate this as soon as possible.. :)

m-p,

I have a 98 R34 GT-T semi-auto too & mine that switch!

If you switch from Silent to Sports mode, there is a noticeable difference. The exhaust note adopts a growl to it - not as loud though as a cannon type exhaust you see on many Skylines & Rex's.

You can tell the difference just parking & switching between the two, but more so when you "load the car up" driving up a hill, then swtch to sports mode.

My girl gets scared when I boot it up a hill (she's not really a car person, unfortunately!), but relaxes a bit when you switch it to silent.

If you check the exhaust just under the rear bumper, you will most likely see two pipes of different diameters feeding the exhaust itself. There must be a valve that the switches controls to toggle between the two.

Mine is a Nismo exhaust (brand stamped on the underside of the exhaust), so I'm thinking it may well have been a factory option.

Wow.. Great, Mean_R34! Seems that it really works in your skyline, so I think I must check my system and have a test soon.. :P I can't perform the check right now because it's already late nite, and seems that it's so dark outside (everybody knows that.. :P ).. Thanks! :(

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
