It really helps turn in, and stability on sweeping corners. I am not using the car for drifting, so Id like to continue to use it. Really comes down to driver preference, And Id like to see how far I can excel with the Hicas. Ive driven Non hicas cars my whole life, And Im liking the technology.

Please dont whore this thread. Lets keep discussions on track.

ahahah PUN!!!..

yeah fair enough but i dnt need a computer to enhance my driving skills.. oh wait.. quote F+F TD.

"i dnt need a computer to tell me about my throttle response" lol makes no sense

problem is its really delayed.well the hydraulic ones are.. i havent driven enough electronic ones on edge to differentiate between hydo and elec hicas. but m still not a fan. bit like attessa comes in a bit late in most cases.

most times the rear would wriggle mid corner as it kicked in late on the GTR and i would have to compensate with the wheel

Time to Dig up an old thread.

As you may have read the issue was off and on randomly last year during this thread. since then has became a full time issue.

We been trying to solve it in another thread here

to no avail so far. The hicas lockbar is starting to look more and more promising. Although still If i can I would love to fix it.

Im after anyone that can lend me a Hicas computer from a R33 that I can test with.

Also if anyone knows , is there any difference between s1 & s2 or -Alsd models in reference to the hicas ecu itself.

installing a lockbar wont help the power steering issue

when I installed my lockbar I figured I didn't need the HICAS electronics at all so unplugged the HICAS ECU and the power steering disappeared - plugged back in and all back to normal

Dale, I'd say it's a fuse or the HICAS ECU itself

Hey warick, yea that thought did occur to me, that when / even if unplugged or disabled, the solnoid in the Powersteering will still be shut off. therefore not solving the ps issue.

Ive checked all the Hicas fuses (reading from the Panel Scematics) and the fuses are fine, is there a way to over-ride the Solnoid disabling the power steering?

With my 33 gtr it had the bum wiggle thing intermittently occuring when driving along. i had an idea it was the hicas system so i removed it and replaced with a lock bar recently. i have power steering still, but the hicas ecu is still in the rear under the parcelshelf although i havent checked all the fuses in the rear etc. im also running a vipec aftermarket ecu aswell with no afm's. i still seem to be having a problem with steering wheel seeming to hydraulically or electrically steering itself suddenly left then right, it sort of feels like when a car is tracking to the potholes in the road but its not that. it still doing this with hicas removed.also it feels like the steering wheel is slightly to the left of centre when driving u put it straight then it heads back towards that again. i was wondering if it could be a power steering issue (i.e. air in the system) also i noticed that the car has a series 3 gtr wheel on it, would this have any affect, and how can i tell if the steering wheel sensor is playing up?

sounds like your front left control arm bushes are gone. like mine :blink:, hicas does not move ur steering wheel.

    • My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered
    • I’ve got one on mine and it’s fine, 
    • No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
    • Ye, in terms of bolting up the "Conversion" from a GT to a GTT is effectively "Use GTT parts for everything" Except the subframe itself, because you won't want a HICAS/4WS subframe. Remember your ABS system will be different too, thanks to GT being the S15 3 sensor system, instead of the R34 4 sensor system for wheel speed. I do not know how people get this to work given R34 diffs do not have a provision for an ABS sensor (they are on the tone wheels of the axles). I assume***** people use S15 gear/R34NA forever when they realize this - Or they convert it to a rear diff/axles that are R33 style which I presume has the singular speed sensor on the diff itself, but then you have to wire it all in and...and... and...
