Yea its definitely still a problem, sometimes the wheel is perfectly still, yet the car feels like a puck on an air-board and just gliding along with my not having any say. Last night going along at only 70kmh the car definitely wanted to go right, I had to seriously turn left and then back to center to get it right :/

OK, so .... what steering wheel do you have on it? More importantly, is it HICAS compatible?

Have you tried to start a HICAS diagnostic? (google it).

Do you know anyone (mechanic) with a proper scan tool that can report on all the computers in the car? My mechanic has one that reports the computers in the car as being Engine, Trans and Steering (trans because R34 auto ECU has trans module in it - even though I'm using it manual) and my HICAS computer is still present but only partially connected (and completely disabled mechanically). That scan tool reports available fault codes for those computers. Worth a look. You can't always start a HICAS diagnostic to find out if your steering sensor isn't working (for example) because you need the steering sensor (and others) to be working in order to get a diagnostic running!! So scan tools can be a lifesaver.

cheers

Glad I found this topic because my car is becoming increasingly deadly on the road.

Going to be looking at delete or lock as soon as I get some cash.

Would you suggest a delete rather then just the lock bar?

or can a lock bar still bring it stable.

I jacked my car up and you can actually move my wheel because my hicas is so loose..

Don't know on R33s. I put a whole non-HICAS rear subframe from a Cefiro into my R32 and pulled out all the HICAS stuff completely (of which there is a lot more in an R32, being hydraulic).

It's also closer to being legal, as HICAS lock bars are considered a modification to the steering system, which is generally a no-no and an engineering exercise at best.

If I were not to have done the whole subframe, I definitely would have bought one of the more serious delete thingos that replaces the HICAS tie rods with arms with bushes on the end.

Standard GTR wheel from what I can tell. It is possible some sensor is broken or stuck, as for diagnostics I don't think they checked that thoroughly as the loose camber nut was found. But yea I might ask them to do that, I'm sure they have the tools.

These symptoms (or at least the one posted above this post) are usually caused by the steering angle sensor....and more particularly by not having a boss that drives the steering angle sensor.

I thought the same thing but the original steering wheel and boss were in place, I don't believe they had been tampered with, it was intermittent and there was no way to guess when it would happen, either way, all gone, all good.

OP, if you can, just get the system removed and a lock bar installed asap, at least the car will be safe to drive, I know how dangerous it feels, good luck!

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
