My 93 R33 GTST came with the Active LSD (I DO want to make it work).  After all the trouble shooting I can do, I've determined that its most likely a bad G Sensor (based on the ECU codes).  Problem is, in the US I can't find any local.  I bought one from Canada on eBay, and another from JPJDM, but both arrived with the red "excessive impact" mark.  So the only 2 I've been able to get my hands on, both arrived damaged.  Both sellers swear they were in good condition prior to shipping.  And the packing was fine, so I'm thinking maybe they "explode" in transit due to air pressure in the plane?  

In any case, Do-Luck makes a sensor replacement for the GTR, but not for the RWD GTST (only for AWD).  But, the plug on my GTST is the same as one of the ones on the GTR.  Has anyone ever tried using a Tarzan Do-Luck G Sensor on their GTST with just the one plug?  Here's the GTR vs GTST plugs for comparison...

They don't explode, the indicator just releases dye when damaged by excessive force. Probably most sellers don't know you need to pack that particular sensor like you're shipping an egg. The AWD cars have pinouts that look like this:

I would see if power and ground are on the same pins. If it is then more likely than not it will work, when I check the R33 wiring diagrams I see that the AWD CU uses the same pins as the RWD A-LSD ABS/A-LSD CU for the same things. It actually seems to me that you might be able to leave the other part of the harness disconnected altogether. Only issue I can foresee is potential fitment issues if the brackets are different.

Keep in mind that the indicator being red isn't a guarantee the unit is not working (and vice versa, an unbroken indicator doesn't mean a working unit). 

It is just a g sensitive tag, the unit itself is independent and may still be fine.

It isn’t absolute no but I wouldn’t want to install one that indicates excessive shock. And I’m not sure a used one is a good idea anyways, the springs and pots in there have probably aged significantly. Modern MEMS like the Do-Luck or Midori Seibi sensor are the way to go IMO.

OK, thank you! It seems obvious to just plug it in and see if it makes the error light go away, but my car has been at the shop for the last month that I have not been able to drive it. So as soon as I get it back, hopefully next week, I will plug-in one of the “damaged “sensors. Thanks!!!

Lol… the one I got from JPJDM was packed like it had delicate eggs in it. Tons of bubble wrap, foam, boxed, more bubble wrap, packing peanuts and then boxed again. 
 

I suppose I will try and plug-in one of the ones that has the red indicator on it and see if it fixes my issue. If that does not work, I may just try and order one of those DoLuck ones and see what happens with just one plug, I have tried reaching out to them, but have not gotten a response.

Unless a box has excruciatingly clear fragile marking and you pay triple for careful handling, any freight company's trained apes will throw any box 40 feet from the belt to the far end of the truck. Bubble wrap does not really stop G loadings from sudden change in velocity from 5 m/s to 0 m/s.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
