Removing HICAS?

[predator]

HICAS is good at high speed along the freeway, but at low speeds and general cornering and flicking the ass out I'm finding that I just don't like how it behaves. Going on other people's comments that's not too uncommon. I wanna slide sideways damnit!

It's quite strange - very different to any other RWD i have driven and i think i've decided over the last few weeks i don't like and want to waste some more tyre

I did a bit of a search but not too much in terms of how to remove it. I jacked up the car the other day and found it was a lot more accessible than I thought, just sticking out there little motor behind the rear axle.

Now, can I simply pull out the elec. plugs and that will disable it or is it more complicated than that? I have seen separate HICAS lock kits - where abouts can i find these and are these essential?

For short term i'm happy to do a quick and dirty fix (and just remove elec connections) as long as it works. Longer term if I can do a proper solution and get a locking kit??

Thanx in advance

try ice peformance...last time i was talking to them they said something about a kit to disable it

predator666,

If you go to the Whiteline website they have some info on HICAS bypass kits, and I believe are coming out with one of there own. For track use disabling the HICAS is a good idea, but for daily driving I would probably keep it. The bypass kits have tended to be quite expensive, so what you have done is a much cheaper option, but leaves you with the HICAS light on the dash.

hey man, i have noticed on this for sale gtst, that he states he has removed hicas, maybe worth pming him to see how he did it...

(when you find out, post the answers up here hehe)

I'll remove the steering wheel and disconnect it in there - going on a previous post that is the best place to do it. Guess if starts acting too funny I'll connect it back up.

GTS-t VSPEC: true in some ways, but I just don't like the way it handles and it seems its fighting my ass end if if I'm doing corners sometimes the way I do (not all the time!). And in the wet well i'm a bit worried how it will react if i lose traction and it goes sideways. In my old car i knew precisely how to control it when that happened at it was me controlling that back end... in fact i used to do it a bit just for kicks to scare those behind me

I want do the bushes fairly soon to give increased traction as well or possibly set it up to try some drifting..not sure, will see.

predator666,

Tell us what the car is like once it is done, I might try it to see the difference.

CLICK HERE

The second item on the page...

That's the proper way to do it..

[predator]

Nissan Skyline R32 GTS-T, KYB Buzz Spec Shockers (Damper Adjustable)

huh? That is the 2nd one on the page?

I already have adjustable zeal coilovers for the springs - dampner and height adjustable. That should do for now in terms of that side of things.

btw: Its an R33 - sorry for not posting that b4.

[TTT]

sorry.. my page didn't update..

it is the 7th item on thepage.. but it turns out that it says for the R32 and 180sx..

[predator]

Thought it might be that one. The R32 one is apparently hyraulic and the R33 is electronic.

Therefore with the R33 it should just be a matter of disabling the electronics. When i think about it though, unless it is actually locked it still might be a bit floaty.

[GTS-t VSPEC]

Will unplugging the HICAS have the same effect as the bypass kit? If so then why is the bypass kitss so expensive?

I removed the HICAS on my Zed (hydraulic system) some time ago, I didn't notice any difference at all in the handling.

BTW the hicas is only active at speeds above approx 70-80kph, and even then only moves the wheels a max of 1 degree.

Like you said, for the R33's it's a bit more complicated cause you have to fool the computer and lock the rack.

If you don't lock the rack, you end up with lots of toe in and when turning hard corners the wheels can actually push the fluid around !!!

I've got a Tomei HICAS lock in mine but I haven't driven any other R33's so I can't compare.

I have heard this, but its mainly taking a corner and trying to kick the ass out. It just "feels" funny when i'm doing it - like the ass end is all wobbly. Of course if the wheels are spinning too much wouldn't it think it was going 70-80km/hr and kick in the HICAS?? It could just be a need for stiffer bushes and stuff which i'll get fitted soon

See that is the thing - I don't really know what its doing and would prefer it just to handle like any other RWD which i've driven for years.

Jay,

Thanks for the link, it sounds like the only real way to do it. I'll have to get the kit when I take it out on the circuit. Is it widly available in Aus?

No problems

I'm pretty sure it's available through UAS or JMS, or they can order it for you. Actually, it might be even cheaper though http://www.takakaira.com/

I was lucky cause my car had it in already when I bought it.

It was funny cause I only found out that it had it about 9 months after I bought it !!!!

Is it true that if you replace the standard steering wheel on an R33 that then HICAS will be disabled?

When does HICAS activate? Is it constant or only above a certain speed?

I haven't had any experience with the Skyline, however the HICAS on the Zeds is pretty much the same.

The steering angle sensor is mounted in the steering column, so if you change the wheel it may not work properly, will most likely cause a fault code and then the HICAS will disable, similar thing will happen if the steering wheel is not fitted straight.

HICAS is active above approx. 60kph and takes inputs from speed, steering angle, throttle position etc. It's constantly moving the rear wheels to keep the car balanced.

I have some really good info on the HICAS which I can scan and post if anyones interested, explains it fully

[TTT]

please do post the hicas info..

[MYGTST]

all you need to do is unplug the motor to the hicas to eliminate it

crawl under the rear of your car and you will se the motor near the diff

unplug the wires(hicaslight comes on ) and hicas is disabled

you may think that it will move freely now,,,wrong the motor wont move at all its locked into position internaly untill its told to move

the lockout kits are expensive because they have a curcuit to fool the hicas computer into thinking its still working so you dont get the hicas light coming on thats all
