Hello. This and SDU are the only English-language Skyline sites I can find. I'm not Australian, but maybe you folks can help a Yank in need.

I have an R32 GT-R and I recently got new tires. I drove around for a while and I noticed that when I go over 70km/h, the steering wheel will slightly start moving to the right, but the car will stay straight. As I slow down, the steering wheel will straighten out again. It's kind of scary. This only happens sometimes. Also, when the HICAS light is on, it doesn't happen at all. This didn't happen before I put the new tires on, but I don't see how new tires would be the cause. The tires are the same size as the old ones.

Is the HICAS system doing this? I had a mechanic check the steering rack and he said it was fine. He's the same guy who put the tires on. I trust this guy since he's been my mechanic for a while and I know he won't BS me. I told him about the problem, but when he test drove it....it didn't happen (of course).

He recommended that I remove the HICAS system regardless of what is causing the problem.

I'm completely new to Skylines. I came from years of driving Impreza WRXs, but defected to Nissan.

Thanks in advance!

in thery hicas is meant to disable itself at high speed

so when you go over 70 its disabling but its default position is a bit off

so get a rear-wheel allignment i guess?

last sunday i ripped my hicas rear end out and replaced the whole subframe with a non-hicas one, i win :blush:

Firstly, if the HICAS light is on, that's an error, and HICAS is disabled.

Back to the problem at hand. You had all 4 tyres replaced? Or just front / rear? How are the tyre pressures? Did you get a wheel alignment with the new tyres? Have you checked the power steering fluid level?

As you know when you get new tyres you need to do a wheel alignment front and rear for GTR's as they are 4WD...

Did get one done?

Then check your HICAS Fluid.

HICAS is suppost to help you with your turning / handling.

As you drive over 80km/h and turn the wheel, the rear wheels are suppost to turn 1 degree in the opposite direction to help with the cornering.

Hi All,

Has anyone found a definative 'fix' or solution to the problem "higeki" raised as I'm now having the same problem as him with the steering wheel turning to the right - it will eventually flick the car momentarially and the steering wheel will re-align itself back to straight and will drive normally?? But it's the scariest feeling when the car flicks like it does...

May need to look into a full wheel alignment asap?

Cheers,

Adrian

mine does the same

i have an aftermarket steering wheel which causes the hicas light to come on during long strait journeys.

my tyre pressures and alignment is fine (just got done)

when its happening i just turn off the car for a second, allowing the turbo timer to keep the car on, this turns off the hicas light and the problem goes away :P

      I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies.

      It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest.

      Use text replace function to auto-link to referred threads?

      By PranK · Posted

      Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks!

      It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers

      Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...
