Now that I have been driving the 300zx for a few days after months of driving ordinary saloon cars I just love the way the Super HICASS helps the Z turn into corners at high speed. It feels very quick, solid and safe and brings a smile to my face every time. Thank you Nissan for this expensive mod you have put on our cars. Now bring on the HICASS haters so I can advise you how wrong you are.:gunsmilie:

I think day to day your right Andrew, you won't feel it. For me I only found it an issue on the limit and over the limit. I take what you say about it being incorporated in some high end new cars however it's my understanding that they are a bit more advanced. Very similar to the conversation being had recently about automatics, they have come along way. I had the early 89 hydraulic version.

They are the same principle; turn opposite direction for low speed for better maneuverability, and same for more agility and stability at speed, however im sure 27 years has refined it much more, and perhaps tuned much better to the power they put out.

Incorrect AGAIN! The low-speed design was a Honda parking aid, it is not HICAS which operates at speeds of 40mph or so and above and is a stability aid.

Calm your horses Si! Medium speed opposite direction... high speed same direction.

You said they turn in opposite direction at low speed manoeuvrability, that is not the case! LOL

Can either you or si put up what bits you used to do the arial relocation as it's the only thing that bugs me on the Z:innocent:

 

Or can you just ditch it and rely on the "diversity antenna"?

Thanks for correcting me about the speed it operates at... I'm not arguing

Joel did nothing as does need regular antenna. I fitted an aerial to the rear windscreen where the old squirter would go. It's quite fiddly and to be honest, not really worth it.

So no HICASS haters yet:) Where's Danny boy?

 

sorry for the delay. been working very hard last few days saving for a new motobike. any how yes indeed i dont like the hicas. no under normal driving maybe its ok after driving the car the first week i felt just wrong for me , i like to know what going on on the back end., and before simon comes at me dont forget i have had lots or fast top road holding car inc lotus and porsche and mnay others so am just going on experience here. for the novice weekend driver am sure the hicas is nice but for tail happy tyre ripping fun i had to remove it :gunsmilie:

Wouldn't listen to him. :lol: His favourite Z32 on the forum is a white Z32 shorty on 19s....he 'hates' white and 'hates' 19s. :rofl: ;)

 

i dont hate white. just 19s on a z isnt not for me :tank:

No worries Dan its not your fault that you are to young to understand the real art in driving fast. :biggrin:

A properly set up and maintained HICAS system works just fine for me and I'm happy to leave it in place. To be honest I don't

notice it operating which is probably as Nissan intended when developing the Z32 over 25 years ago.

 

Today a number of very high performance cars including the Ferrari F12tdf, Lamborghini Centenario LP 770-4 and Porsche 911

GT3 all have rear wheel steering which operate on the same principles as the HICAS system. I would have thought those

manufacturers must see a benefit to have included the system for their customer's driving experience.

 

Yup - what Andrew said.....:thumbup:

 

I'm keeping my HICAS.....

 

.......And electric aerial too, even though I also have DAB and use a little plastic aerial on the windscreen...:wink:

No worries Dan its not your fault that you are to young to understand the real art in driving fast. :biggrin:[/QUOT

 

lol the real art is to steer with 2 wheels, but i guess when your getting on you need all the help you can get :cowboy: lol

Now now if you are tail happy and tyre ripping you are not going anywhere fast Dan. You know I'm right :yes:

well yes but am having fun. there is no way i could have left it on. every time i drove it it was on my minds are the rears going to flick the car when i dont want it do. hicas went bycas :gunsmilie:

We talking about hicas, or super hicas? Ditched the hicas on my old zeds, eventually I'm buying JaiKai super hicas, not sure it's justified but have something against the hydraulic system the later electric system I want ( someone removed it from my zed very disappointed when I went looking for it)

Both the hydraulic and the later all electric systems were called Super HICAS in the Z32. I think it just got shortened

in this discussion to just plain HICAS.

I thought it became super hicas in '94 when it became electric, I there actually a "hicas" then?

I was under the same impression.

That's what I thought.

 

Super hicas used a computer to measure stuff like how far and fast steering wheel is turned, lateral Gs, yawrate, and road speed. Then calculates angle to turn it. Hicas is just hydraulic valve controlled by ECU (only uses speed wheel is turned, speed and steering angle)

 

Si come get me[emoji14]

It's always been Super HICAS! Here is a copy from the Japanese 1989 marketing brochure:

Give me strength!

Conflicting information is doing my head in.

HICAS or SUPER HICAS is widely excepted too stand for High Capacity Active Controlled Steering (Super HICAS was a updated version on later models)

Earlier HICAS versions used hydraulics to steer the rear wheels. The hydraulic system was powered by the power steering pump and used speed sensors to determine how much and in which direction to steer the rear wheels. Later versions, called Super HICAS, moved to an electric actuator for the rear steering rack, making the system much lighter. The Super HICAS system also used its own computer to control the system instead of speed sensors. HICAS and Super HICAS rear wheel steering is limited to about 10 degrees in either direction.

 

While I cannot doubt your source, it would make more sense to have a base hicas, and then upgrade it and call it 'super hicas'

Conflicting information is doing my head in.

 

And the source of that is?

Wikipedia and some skyline article. (i know, i know) but it seems widely accepted on the internets

 

To be clear I'm not starting a fight, I am having a discussion
