Hicas Crap

Just thought i would grumble though this question on my mind. I love the idea of hicas, but only when it works.

My hicas light comes on after traveling a long distance 150km, i don't know why(don't really care because i only do that once in a blue moon). BUT

When i sway the car (left right etc) the whole rear end seams to go limp like the bushes have droped out. If i straighten out for a bit, it corrects itself.

So my questions for those of you who got though the boring part.

#1 Firstly is limp end normal hicas traveling highway speeds or is it a sympton of the light. (havn't tested it before the light comes on). I ask this because i want to get it on the track.

#2 When working is hicas suitable for circut (speeds able highway etc).

As i said before i love the idea of hicas but maybe it's only ment for -100 speeds. Scares the shit out of me, especially when it sways at high speed while and the arse of the car is crabbing behind me then i hit the breaks because i think the wheels have fallen off and crabbing is accentuated so i feel like my arse is traveling faster than my front lol lol

PS not as bad as it sounds but when the car is pushed into swaying seams to be a computer error where it counteracts drivers steering with hicas.

:D

1. Hicas can act unpredictably even when everything is working fine! so if you have a light coming on, then one of the sensors or something isn't working (or low powersteering fluid), which could make things worse

2. Never

Buy a lock bar if you intend to take your car on the track.

Usually sway both ways a few times then the hicas kicks in and my arse goes limp. Have a feeling that i'm just going to have to rip it out, should save a few kg's, also don't have to fix that light. Anybody know a good DIY forum to start getting it out, also good lock bars????

thanks for your help guys. :)

HICAS on the track is shit, it makes the back of the car wave round braking from high speed amoungst other things.

bah - I can't say I've had that problem on my R32 GTR brking from about 220-230kph in the kink on Conrod with the semi slicks, or from about 210kph for the Karousell at Lakeside on Federal road tyres... there is a bit of trail-braking there if you provoke it, but that is a useful thing...

but if I was having problems with the HICAS system, I wouldn't bother trying to fix it. Just get the lock bar and remove the HICAS if its causing problems.

      R33 GTST Sh*tbox to Polished T*rd

      By Yeetus · Posted

      Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -

      Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.

      Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
