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.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      I would just put EBC back on the "I would not use their stuff" pile and move on.
