HICAS boss Vs non-HICAS boss... - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Hi folks, have a question for you learned ones

...

I managed to get myself a Works Bell Rapfix hub

. As a cheapskate I bought a non-HICAS HKB boss kit (the N-6 model I believe).Now the WB hub fits nicely onto the HKB boss but when I offer it up to the car it wont get past the white plastic ASCD unit...Now my car has the HICAS removed and I'm tempted to get rid of the white plastic ring which, if I do, will allow the boss to fit perfectly.

My question is..is this ring solely for HICAS and can I get rid or does it provide the ATTESSA with wheel position info and must I keep it??
Basically can I bin it or not???

A confused,
TT

I used a S13 non-hicas Momo hub kit on mine as I had one already and ditched all the hicas related crud on the steering column. Did end up using a few parts from a S13 to retain the indicator self cancelling though.

Haven't noticed anything amiss with the ATTESSA since doing it.

Thanks for moving the thread Robbie

Well, thats 2 out of 2 for ditching the ASCD ring then. Any specialists want to add their tuppenceworth?? I've looked on FAST to try and see if the ASCD ring interacts with the ATTESSA but no joy...

can anyone back up what Andy H and mambastu are saying that removing the ASCD unit WILL NOT affect ATTESSA???

One more vote for removing it and it goes

I was under the impression the ATTESSA also required steering angle input. May still feel like it works, but if it thinks it is in the straight ahead position all the time, probably won't work like it should with lock on.

I thought so too originally but I checked a ATTESSA diagram that was posted on here a whileago and there were no steering angle inputs into the ATTESSA ECU.

Heres the thread R33 ATTESSA Pinout

Phoned RK a few minutes ago like I should have done initially and they say its good to go, so it has. New wheel on and I'm a happy camper
