with the Extreme TSC (my 32 gtr also came with one which i havnt played with yet)

silly question,

im assuming when toggled to 4wd its not active at all and the usual system does what it does.

when ON, can someone confirm exactly what the gain is doing.

on the box, 0 = (standard) 10=(max front torque)

which it clearly not. 0 just = skiddies which is not standard

does 10 = standard as in as much 4wd a standard = grip

and 5 meaning half way so my gauge would only read %25 front torque? or does 10 give me more FWD torque than usual.

0 shouldn't equal rwd skids if its fitted correctly. I have an extremeTSC fitted to my 32 and my understanding is on 0 the attessa functions as normal. As you dial up the gain, it amplifies the signal to the attessa computer which results in more power being sent to the front wheels.

It's been ages since I've done it so someone else can confirm. But it something like this: Unplug the attessa plug above your right leg ( sitting in drivers set ) the one used for bleeding attessa,

I understand its only in the R32 manual to put it into rearwheel drive and that is when its rolling just turn the key on and off (like a crash start) and it goes into RWD. I did this 2 days ago in my 32 to drop some lines. Great fun with 370kw....

Yeah there are different ways to go about it. The Full Race ETS computer does it all and can stop the system from priming or open the valve and deprime on the fly and vice versa. Which is neat, no need to stop and reset. Basically gives u complete control. However if you still have the A-LSD, when you cut power to the attessa to give you Rwd, you will also be cutting power to the diff, give u a single pegger.

I wouldn't worry about transfer damage. Myself and plenty of others have been running systems like this for years with no adverse affects. Even the Nissan manual explains how to put R33/34 into Rwd for dyno etc

Single pegger doesn't sound good.

What does the Nissan manual say in regards to getting it into Rwd?

Unplug the attessa plug above your right leg ( sitting in drivers set ) the one used for bleeding attessa,

Turn ignition on and within 10 seconds push the brake pedal at least 5 times,

Awd light should flash continuously and you are Rwd. Attessa valve should open and not prime system.

Like I said it been awhile so hopefully someone will confirm.

But it will be the same deal if you have A-LSD, will take out the diff also as they both work off the same pump unit.

I also have one of these that i got with the car. Think of the 2wd 4wd switch as like an on off switch when on 2wd the dial will do nothing at all and car will be rwd (mine still rotates front wheels if all 4 wheels are in the air, but torque gauge reads zero and wheels can be stopped by hand)

You can switch from 4wd to 2wd on the fly but not back again (have to turn off ignition to engage 4wd)

With switch on and dial set to 0 which my understanding was this was supposed to be standard (as in no controller fitted) car is fairly tail happy and it allows you to get fairly sideways before front torque pulls you back, as i understood it this sounded pretty consistent with standard r32 behaviour.

I usually leave mine at 0, if I'm pushing it abit and want less rear step out i turn it upto 3 or 4 if it's really wet i might have it on 6. I have never felt the need to go higher than that.

I know other systems (ruzik, hks etc) are much more comprehensive but the extreme tcs works pretty well for me, makes a massive difference especially in the wet.

Anyone have anymore experience with the HKS ETC?

I'm currently running the extreme TCS (came with the car) but a good friend of mine is giving me his HKS ETC.

I would assume from what I've heard the HKS gear is better??

Joey,

I have the HKS ETC and EDA in my car (my car used to belong to JMW on pg 1 of this post.)

I haven't used any other TSC, so I can't provide a comparison.

But I can confirm it gives full control of front torque in quite fine adjustments, with manual and auto modes as described in the gtroc link in JMW's post.

My understanding is that front torque can be locked at a desired level (or lack of) for all road speeds, automatically controlled by the ETC and EDA with a specified ceiling torque split value, or left as the standard attesa system would adjust.

Cheers,

Adam

Hi Adam

Thanks for the reply mate.

From what your saying the big advantage of the hks unit is that the front can be locked at a desired torque for any road speed. I'm guessing this makes a big difference for launching/drag racing.

Did you have problems with wear on the transfer case?

Cheers

Yeah that's right. Full override to a constant setting for any road speed, a drag race mode that uses the EDA to adjust front torque with speed, or normal mode that leaves the attessa system alone (i think).

The off setting seems to do the job most of the time. Hard to tell if that is any different to normal atessa having not driven a 33 gtr with the same power but normal attesa controller.

From what i understand, when on the unit overrides the stock settings with its own control system, more then amplifying/bending the sensor signals like some of the other devices mentioned seem to do.

To be honest I don't actually use it very much as I haven't run the car down the strip and i don't see any benefit to locking the torque split full time for most of my street/hills driving. IMO using the locked or EDA settings would make a big difference to launching (I think the EDA mode is more aggressive in increasing torque split to the front wheels), but i think if it was used often it would probably shorten the life of the drivetrain.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
