Hi guys! Hope i've posted this in the right area.

I've owned an r32 gtst for 2 weeks now, and today i noticed that my Hicas ECU is missing...

Looking under the parcel shelf, theres 3 unconnected harnesses. I definately have the Hicas steering rack fitted. It has the hydraulic lines fitted to it and looks fine and unmodified externally.

My steering does not feel abnormally heavy at all, as others have described.. nor does the Hicas light on the dash illuminate.

My question is, should it still work? Or is it even working at all (how can i tell)?

Thank in advance!

Phil.

If the HICAS computer is gone, it will not work as the computer controls what it does and when.

The light isn't on because the computer sends the warning signal to the light.

With my car the steering did go heavy after the computer was removed though...

I dont think it's good to just leave the rack like that with no computer, I think there is a small amount of movement still in the rack.

Thanks for the speedy reply Salad.

Is there any way to test for rack movement at all? Would i just turn the wheels to lock and watch the rear wheels for movement?

Should i try and source another computer and see what happens? Does anybody know what a second hand one is worth?

yep you can feel hicas, and its why majority of people remove it.

It sorta feels like the rear of the car is stepping out but it isnt haha

Plenty of threads about hicas, just give it a search.

Some people remove due to its unpredictability and some learn to use it and take advantage of it.

If you planning on drifting, best to remove it.

since your ecu is gone, the only way the rear wheels will turn is by force of the car tuning them (dunno if that makes sence), you need to check and see if there is anything on the rack locking the rams into place. If there isn't anything locking the rams, the rear wheels will turn by themselfs at high cornering forces.

the ECU controles the solenoids to open and close, and the solenoids control how the rams move. so the wheels can still go floppy at high speeds. When my hicas was playing up it did this, not fun when you don't know when your wheels have a mind of there own.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
