Depending on how this ets pro works ill go with the manual setup. This is really all an experiment really. Im after what works for me the simplest way. I do really want to try the manual setup. I still collecting parts for the setup an thought in the mean while ill give the ets pro a go. I looked over some post and Geoff mentioned that i can run manual mode and when the car is on its way flip the switch to 2wd mode. If i wire the speed sensor with some sort of controller (computer) to interrupt the switch on the ets pro 4wd 2wd mode.

Im suprised that lots og guys here dont really drag race. Someone should make a drag racing section.

You'll be surprised how much difference just altering the plates in the transfer case will make.

IMO it's 70% mechanical and 30% electronic.

The gains you get from the transfer case "mod" (ie, rebuilding, altering the plate arrangement etc) is just exceptional. You get FAR more front end transfer immediately.

It could likely be all you will need, as Joey said earlier and IMO - best post thus far.

Have you done the bolt mod, how does it work?

Yep I've got it, I haven't really had a play with it but the car does feel like it hooks up a bit better..

Obviously I could preload it more but I would need to be careful on the 2wd dyno as to not burn out the t case

Main problem with that mod is it can be hard to seal the thread so you may get a slight leak

So what's the mod?

I searched but couldn't find anything.

If you cant be bothered explaining, just point me to a link.

Thanks

So on the back side of the t case there's a round part that protrudes out.

You still and tap a thread and use a bolt to pre load the actuator.

I'll get a photo next time it's on the hoist

It makes lots of sense. It would lock the 4wd up like a evo is or any all time 4wd car. Thats what i reall want. But only in a straight line. After that its a nightmare on the way home. So i would rather manipulate the attessa pump for full lock going with the ETS PRO from full race. Or better yet do the mechanical method with the pump. But i wanted to make sure the disks were all good. Then focus on everything else. Good ideas guys. Even when i try this ets pro next week ill do the mechanical pump and try to make a system that has both streetability and drag racing (full lock in mind). By turning a bottle valve and separating the two systems.

We couldn't believe how easy the transfercase was to do. I would recommend it to anyone thats a mechanic.

I have finished my installation of this ets pro. What i would like to know is. ?? My 4wd light is on. I installed it just as one mate on this did. I would figure the light would come on because the attessa computer picks up an ooen circuit see how the pump wires need to be cut and hook up directly to the ets pro. ???

Can anyone shine some light on this situation

Ok so we figured out today that the ets pro is working and well at that. We are now leaving the line with full 4wd lock and can feel it. This is in manual mode and hitting the 2wd switch in 3rd. We really dont need to time anything as we can simply feel the difference with these new friction disks. We would like to add the following.

1. We would have loved to see the actual torque split gauge still work for the 660 dollar we paid for the system.

2. We would have loved the company to offer stickers for the modes and percentage for the manual mode nob. Next even a 2wd drive and 4wd sticker.. simple no big deal.

3. If there is a mismatch in tire size the system has no way of knowing this and will damage the transfercase. Thats bad. But we figure the reasoning would be just for racing. ? But the product didn't even come with instructions in the package. Thank god for this site.

4. In our opinion for its to be called a full stand alone system it should first be better at self diagnosis than the oem system. Opinion here. By tracing all wheels sensors. We understand the way it works has nothing do do with wheel sensors. But find it fare as a statement. but wait who cares its simple.

5. The company should mension if its better to use the product in 2wd mode or 4wd mode for simple street driving. As we cant monitor the % of the way it engages the front wheel keeping in mind that there is a nob. It would be nice if there was a way to utilize the factory torque spirit gauge via some sort of output.

Finally we would recommend this unit to anyone. We simply wish the price was way cheaper. So we offered just some ideas to justify the price. We end by saying this is by far the best attessa controller we and i have ever used. Simple. Thanks full race.

You referred to the pump but Isn't it just the solenoid wires that are cut?

I thought the original atessa control unit still think it's working so should not trigger the light on the dash?

Have you completely removed the original unit?

Edited by s2d4

So you simply rebuilt your x-fer case as standard? Does ANYONE want to spill the beans on what "altering the plate arrangement" means? There are a handful of threads talking about this but no one actually cares to explain it.

There are 2 ways to measure when front wheels get engaged and by what amount, either a pressure gauge on the hydraulics or a volt meter on the solenoid wiring or both. That would be fairly accurate I think

Search harder

Yes its been posted a couple of times. It goes like this:

Transfer case rebuild

Its not the adding of plates.

Its the arrangement of them

There are 19 plates in the standard setup, 12 outers and 7 inners to make up the clutch pack,

Outer = O, Inner = I when reading the layout below.....

Stock is IOOIOOIOOIOOIOOIOOI

Full max grip rearrangement would be IOIOIOIOIOIOIOIOIOI

You only need another old transfer case to rip the plates out of to rearrange your old setup, scavanging the extra inner plates to use, you need to select ones of the right thickness to end up with the correct end clutch pack thickness so some mix and matching is required.

You don't need to go full grip, you can make up your own arrangement of plates like something in the middle like IOIOOIOOIOOIOOIOIOI

Same theory as playing with a Cusco LSD clutch pack arrangement, see page 9 below.......

Yes i seen this post before. Thanks for that guys. I thinking of changing the arrangements as well as i should have done so when i rebuild the transfer case.:(

But i dont mind doing it again. As i have 7 good disk that came out.

Has anyone tried a full lock setup. To see how it works. I have my switch set right as i go into 3rd so that my fingers can hit the switch to rwd mode. See the attached photo.

Im just wondering how it would work on a full lock arrangements for street driving. ?????

As of now i notice that the ets pro applies more transfercase pressure as im driving normal so i opp to leave it in rwd mode and inly use it for drag days.

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too. 
    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!
