What Are The Electronic Boxes In The Rear Of My R33?

[mattysaidso]

Hi,

Just wondering if someone can tell me what the following electronic gizmo's do:

The smallish one that lives under the synthetic parcel shelf near the top of the the drivers side rear suspension in a R33 GTST?

The big one under the parcel shelf in the boot fitted to the under side of the steel parcel shelf drivers side R33 GTST?

Thanks

Mat

On further inspection, you already asked this 17 months ago

Unsure about the one undernearth though.

without pics hard to say 100% but the other one is probably the HICAS/Power steering ECU

Leave them alone

wow, shows how good my memory is/was.

car is unregoed track car with hicas locked out.

Figured that the larger one under the parcel shelf was hicas related??? but unsure of its function when removed?

as you remove it you'll loose extra power steering assist, it's there to detect lower speed and allow more assistance to the power steering rack and as you hit a certain road speed the assistance drops off leaving you with a more planted car

You basically lose all power steering. With no power to the solenoid it applies minimum effort which is probably about the same effort it applies at around 100kmh

I've had my HICAS ECU recently play up and it was horrible going around car parks etc with no power steering. Granted that isnt a big concern for a track car, but you will still still find its not as nice on slower speed corners

Geez way to make things complicated Nissan.

Thanks for the info guys

You might be able to wire a unit in from a non HICAS R33 as it will just do power steering. But not really sure how hard that would be
