Link vi-pec expansion

Hi everyone. 

I have done a few searches on here and Google but am unable to find any diagrams that explain how to wire up the expansion cable for air temp sensor map sensor and wideband can lambda. 

I'm fairly handy at doing things on engines and wiring so please no negative reply

Having said that the simplest diagram for idiots is often the best for everyone for anyone else who is trying to do this down the track. 

If anyone has or can put up the information i need it would be much appreciated. 

My ecu is a vi-pec plugin r34gtt and engine is a 25/30 neo in a lc gtr torana. 

I have build thread on here for engine and i think there is some pics of the car in that thread too.

Thank you in advance.

Have you looked on the Link website? As I recall (it was a few years ago) you take the lid off the ecu and there is a terminal to push it on and you need to snip the casing to allow access to the wiring (unless I am confusing it with the cable for the display) - I think the instructions came with the cable - but otherwise you can email or phone  them for tech support. Or skype but probably not on the weekend

Never used a link before but my advice is that if you really aren't sure about wiring, pay a professional to do it. It might cost but at least it will be done right and you won't have a problem with it in future. Chasing wiring troubles is the worst.

I have with the vi-pec dealer and link tech support. 

Oh good, excuse my scepticism. Assuming you have a link branded exp cable, your yellow wire (PIN7) going to expansion port 1 is an output, not an input. Just going by what the software says.

 

Would hate someone to find incomplete information. Unless of course, the hardware has changed from whatever vipec you have to whatever the current link is.

      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!

      Mistakes were made, my R34 Story

      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...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
