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



Small on in the back right corner near suspension refer to this:

On further inspection, you already asked this 17 months ago :P

Unsure about the one undernearth though.

wow, shows how good my memory is/was. :wacko:

Leave them alone

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 :)

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
