Question:

Hicas, when dose it work, how does it work, why does it work...

This is for me and other who would like to know...

Is all wheel steer as i know, and it works at certain speeds for handling..

Is this correct..

What speed?

Can you feel it?

I have a R32 Gtst and its got hicas... im sure it works, i swear i can feel it...

But i put it up on a hoist, put it in gear hit like all speeds turned the wheel and no rear wheel action...

Whats goin on?

Any help would be appreciated:D

You won't get it to work while the car is stationary unless you put it into diagnostic mode which is not straightforward.

It deflects the rear wheels differently above and below 60 km/h as less defelction is required at higher speeds.

In a nutshell the idea is to try and induce understeer for safety and for 90% of people it is probably a good idea to keep it connected.

There is a long thread on HICAS on either the handling or forced induction forum. Try an advanced search for HICAS with threads/posts by Sydneykid and you'll get the whole enchilada explanation.

In a nutshell the idea is to try and induce understeer for safety and for 90% of people it is probably a good idea to keep it connected. What can make the car go mental is the fact that it is controlled by an old tech, slow ecu and if you are balancing oversteer on the throttle it suddeny goes 'oh I know, I'll help now by inducing understeer' with the result that it will turn the rears and reduce the friction level of the contact patch even further, possibly causing a lose. This is the time you go 'stop helping, you sh$t box'.

oh oh oh... yes i get you derrr.

Sorry

Try the DIY forum or the susp forum, there's a tutorial there. Good luck, there's also a lot of cases of people having a rant because the diagnostic mode procedure is so mental. It's funny seeing the car sit there and twitch it's back wheels from side to side.

      All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.

      roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.

      I think he was only proposing to use the wire, not the sender. Simply because it runs from the right place to the right place. Personally, I wouldn't hack up the factory wiring like that. I'd just lay in the Defi loom.
