Clutch Switch In R33 Gts-t


Recommended Posts

I was going to wire a clutch switch to my ECU for launch control/flat shift.

Found there was already one there in the clutch bracket.

Any one know what this is used for?

I could put another switch there but that would involve making up some brackets etc. If I can use this existing one I'd be stoked.

If it's not used for anything I could wire straight off it, or if it is used - I could wire up a relay to repeat the status of the clutch to the two circuits.

If anyone has a circuit diagram that would even be better.

Thanks,

Aaron.

OK got a bit more information:

The clutch switch has its own error code in the HICAS diagnostics. Is it just used for HICAS?

I have a HICAS lock bar on the car so might not need this and can rewire?

Anyone?

I've managed to get a copy of the engine chapter of the workshop manual - doubt it's gonna be in there but will have a look tonight.

Otherwise I'll have to trace the circuit back...

i have had my clutch switch hooked up to launch controll (gizmo launch interface) in my r33 gtst and had no issues with Hicas.

So i dont see how you will have any issues if i did not :)

Excellent, just what I wanted to hear - thanks for that.

Did you cut the existing wires off and rewire?

How's the Gizzmo? Find it useful? Is the flat shift more a lil more beneficial than the launch control in a RWD?

I never actually set it up properly yet.. lol... I kept showing off pop pop bang bang and it cost me a gt35r so I leave it turned off now :D

Ouch...how long did you have it before it went? Maybe not such a good idea then...

Did a search and some guy had one for sale a while back and wired it like this, looks like you got this one :D Hope you don't mind me pulling this pic up:

Thought i had this sussed but what is that rectangular object all taped up in the pic with the terminals coming out?

hahahaa thats in my car atm :D

It was in there for about 2 months.. i gave it a little workout but not as much to wreck a perfectly good turbo, my turbo was flogged for years before this unit came along.. it just speed up the process.

Its a relay, the mafia hooked it up because the switch is the reverse of what is needed he made the relay setup for it which worked well

Ahh thought so - all sorted now.

That makes sense now, I need a normally closed contact, I'll test the switch tonight to see which it is and whether I need the relay.

Thanks for the help :)

    • Took a little trip  went to nismo hoping the get my fuel tank hoses and unfortunately they told me they didn’t have stock luckily I was able to go to a Nissan parts store and they were able to order them in for me  then can home and cleaned the tank with some degreaser and fitted the new hoses before putting it back in the car 
    • 100% I’ll hack into the 33. Strap a turbo onto the RB25DE and/or put the 25 head on a 30 block. 33 passed in cos the reserve was too high. I’ll try lowballing it again and negotiate. Aim is to have it landed and on the road for under 15k, then spend the same amount on top in mods.
    • It's generally best practise to run 1x run without VCT enabled, then 1x run enabled till redline. Overlay the two torque graphs and you'll find the desired RPM to turn off VCT. Sometimes, it might be even worthwhile turning off VCT earlier control torque/cylinder pressure and using VCT purely to spool the turbo.
    • They sell them in Malaysia for about $4
    • First time I ever have issues with Amazon, but my wife often tells me to keep an eye out for fakes. It finally got me. I wrapped up the conversation with Gates. The gentlemen I was talking to seemed to hate his job but the response time on their technical support is outstanding. He stated that the hose is marked with some variation of "SAE J30R10" but that if you only purchase a 1 foot length like I did, it is possible to get a cut between markings and have a blank hose. To no ones surprise, he stated the swelling and "gummyness" isn't normal and to replace/buy from somewhere else (He mentioned NAPA). I'll toss a small end of the new one in gas for a few days before pulling the hanger out again, just to be safe.  Hose should arrive Monday. For those running multiple pump in tank hangers, you know the joys of getting them out and back in. I'm surprised I haven't destroyed my level float yet.  Lastly once I wrap all of this up, I'm planning on hitting the dyno again in 2 weeks while I'm on vacation. I realized recently that my VCT is set to turn off at 5000RPM. I'm surprised it wasn't increased while I was on the dyno last. I'm expecting I can increase it to ~6500RPM, if not more. Should hopefully get another 15-20kw out of it. I also want him to revisit my knock thresholds. I'm occasionally getting false knock around 3000rpm.
