spheres or springs?

No

Just had a thought, If I have front globes on the rear, would this cause my bottoming out issues?

I did find reference to other internet articles saying
" The rear globes are bigger than the front ones, 500 cc vs 400 cc. The rears also run a slightly higher pressure, 2.65 vs 2.26"

I'll ask my mech about this, perhaps as its a UK amazon its different

Yes, the rear OE globes have a greater volume and higher nitrogen pressure than the fronts. They are physically larger. This is to accommodate pressure and volume flow variations due to cargo weights and the +3 inches addition travel the rear shock actuators have over the front shock actuators. If you have the OE smaller, lower volume, lower nitrogen charged fronts fitted to the rear then you would absolutely bottom out far to easily, particularly if your rear height is lower than design.
I believe the UK based company who provides after market Citroen globes (with adaptors) for Toyota/Lexus AHC applications uses one globe size but varies the nitrogen precharge to suit front or rear and or "sports/heavy load" applications. It's been a while since I explored their products so I may well have it wrong.
Check under your vehicle to see what's actually fitted.

I looked on the ones that came off but the printed numbers are very different to ones found online

Numbers on them are:
2626-0934
Muv 200-500

I'm unsure how to check if the ones on the car are large or small?

For OE Toyota the larger rear sphere is approximately 105mm deep and the smaller front is approximately 90mm as measured from the flange face to crown of the sphere.

MUV 200-500 = larger rear (500cc volume)
MUV 200-400 = smaller front (400cc volume)
At least that's whats stamped on some old '99, '02 and '06 globes I have laying around.

Are there different versions of 'techstream', one better than another and what version of 'windows' would I need t have on a laptop to work best with it?

Thanks in advance. I read so many different posts about it....it has me confused.

There are many versions of ripped off techstream. Any of them have the same functionality with our cruisers. 10.something is the newest if you want to hook to newer toyotas. What matters is the ripped off cable. You have two options, firmware 1.4.1 or 2.0.4. You want 2.0.4. The least expensive place I've found is on aliexpress.com search there for "mini vci 2.0.4" only 1 result should come up and it's $30us shipped.

For some reason my edit explaining the PC requirements didn't show up.

Techstream likes Windows XP. There are ways to put it on newer versions. For more info there search google for "tundrasolutions techstream Windows xxxxxxxx" with your preferred version of Windows replacing the x's

finally got techstream
data values attached

what are every ones thoughts?

 

[PADDO]

You need to also provide actual vehicle height measurements (axle center to fender bottom) to put everything into context.

 

[Quade]

Front is 47.5cm
Back is 50. 5 cm

 

[PADDO]

Front heights should be closer to 495mm both sides (cross level) and rear should be closer to 520mm. So raise height at each sensors about 3mm and recheck, FR maybe slide it up 4mm to balance with FL as best you can, they don't have to be identical values, but close is good. It's an iterative process. When your heights are where you need them then take new pressure readings. This is all suppose to be done on flat level ground, no extra weight in/on vehicle.
Still bottoming out at rear?

 

[Quade]

Thanks!

Yes still bottoming out when loaded and on soft setting,

I presume I can adjust these settings within techstream? if so, any ideas which screen I do that in?

 

[PADDO]

You physically need to loosen, reposition, tighten the front height sensor links and the rear sensors' lever arm. The height sensor adjustment FSM pages have been posted previously and will come up with a mud search.

I'm glad I asked!

Hi Paddo,

Can you tell me; In Australia, is it possible to test neutral pressures using techstream on a 2006 HDJ100
Been researching this site and struggling to find an answer.
New car for me and history somewhat unknown. AHC seems to be working ok, graduation results gave 8.
Tossing up whether to keep or change for after market suspension. I really want to keep. TIA.

 

[ihadmail]

Techstream has a region selection, even the hacked version.

I have no experience using it though I've seen members here and on tundrasolutions discussing it.

Sorry I can't give a better response for you.

I'll say it's pretty much a certainty that Techstream is compatible with your diesels AHC system, the question I can't answer is what vehicle interface cable (16 or 22 pin) running what ISO/SAE protocol is required? For example, here in the US we can use a cheap knock-off of a propriety cable that has a 16 pin obd2 style connector which runs the J2534 standard interface and we need what's called "K line" support to read data on pin 7 of our 16 pin connector. If you can eye ball your OBD connector and also confirm what interface protocols you need and order accordingly you should be good to go. The AliExpress ones referenced back a few posts in this thread may well do the job, just ensure you order 16 or 22 pin connector. And in worst case you could use a brake system pressure gauge good to 10MPa and a M7x1 adaptor I believe - I can check the bleeder screw thread if you want to try a gauge. It gets tricky with the many regional and petrol/diesel interface protocol differences through different model years. Have you looked on LCool or some of the Aus LC forums to see what other blokes are running? Global compatibility my a$$!
