Seen this video before and it amazes me how long it takes for both the lsd or tc to engage. I wonder if it would be possible to reprogram for the TC to engage quicker when in 4wd.

I don't have my Dmax yet so I have only been reading other owners opinions
It seem most of what I have read so far say the TC in the Dmax is not as good as other vehicles Toyota Prado was used as a example .
Nothing a few grand and diff lock or 2 wouldn't fix .
I also discovered that most owners don't know how to operate their TC ,
In 2WD and 4 High
A one second push of the TC button disables the engine retardation feature and the ESC , but you still have the TC working braking each wheel as necessary.
Push and hold the TC button in for five seconds , disables the TC completely
When in 4Low Range the ESC and the Engine retardation feature is disables automatically
Push the TC button for 5seconds disables the TC completely
I think that's right , now can someone go try it for me .
Also read the the Hill descent control will brake each wheel as necessary when in Low 1st , when there is no driver input to the throttle or brake peddle , it's automatic there is no button to turn it on/off
Hmmm that has got me interested sounds like BS , I would think it would probably be of more benifit with a auto trans than a manual
If it actually works

Actually what I wrote on the other forum was:
In 2WD and 4WD High Range
When you press the ESC button for one second, this will only stop the Traction Control from retarding the engine revs. The TC will still apply the brakes to a spinning wheel.
When you press the ESC button for five seconds, this will additionally stop the TC applying the brakes and also disable the Electronic Stabilty Control.
In 4WD Low Range
When selecting low range, the TC engine retard function and the ESC are both automatically disabled. The TC will still apply the brakes to a spinning wheel.
When you press the ESC button for five seconds, this will additionally stop the TC applying the brakes.
And yes, that is exactly how it works. I have tested and proven it

No experience with this but have read about it. TC brakes individual wheels but the TC sensor is looking for a spinning wheel so not sure how it works down hill if a wheel is not spinning. Think I need to find a steep hill and try it out
If it's like the MU-X it will work very well. Just uses compression braking AFAIK. Was puttering around Mt Terrible this week. Dead easy - barely walking pace.

Yep Ziggy that's how it works , since getting my Dmax in January this year ,
I have given it a fair workout on some steep tracks both with and without the Tvan .
The down hill decent control is quite good for a auto trans , still not as much compression braking as a manual the traction control is better than I first thought , I had it working overtime climbing a track towing the Tvan didn't think I would make but it just scratched it way to the top.

Anyone had a GVM upgrade done on their DMax
I can see the problem of being over weight becoming a issue ?
I know when I'm on a trip my Hilux is way over .

Hi.
The only problem/reason your vehicle is overweight. Is not the MFG.
It's you putting too much into a vehicle you KNOW. B4 you start, is too small for your needs.
Don't blame the Highways when they pull you over the scales.
It's your choice to do it.
I Go around Australia (East and Central/North and South.) with a GU Patrol 2002.
roof bars and Tinnie/loader. Outboard fishing gear. 80 ltr Waeco. Tools, Spares. Genny
Missus and cat.
In front of a 6.5 mtrOffroad Caravan. with Solar,shower, etc etc. for 3 or more months.
EVERY yr for a long time.
We never go overweight when on bitumin. Have near 1\2 ton to spare with empty water tanks.
Just fill them when going off road and slower/safer.
I check the weighbridge every trip on the way out of town for 14 yrs so far.
If you going heavy either buy a vehicle to suit.
Or go lighter. Think of the missus and kids safety. and others on the road.
You are NOT insured if you have an accident and are overweight
Think how you would feel if you injured one of your kids
or wrote off somebody's Merc etc.
Just mix and match for your own safety.
From a 70plus old fart that drove commercial for a lot of yrs,
and saw a lot I didn't want to while doing such.
I still do.........

Hi guys I have a Q on the My15 DMAX. I'm going to put front and rear E-Lockers with 33'' tires. Before you say The 33" do fit with a little mod and 40mm lift.
The Q: Should I change the diff Gearing to suite the 33" tires if so what ratio would be the best suited. I think the ratio is 3.7 I'm think a 4.1 would be the ratio needed.
What do you think Tink I recon you would be the man to know.

What size are the tires now? If you divide the new tire diameter e.g. 33" by the old diameter and then multiply your original diff ratio e.g. 3.7 by that number it will give you the ratio to maintain the same gearing and that way it will not interfere with your speedo reading as well.

Hi oldlux thank you for your info. the OE tires 245x70x16 new Mickies 285x75x16 33/31*3.7 if the finle drive is 3.727 then if I have worked it out correctly it should be 3.967..is this right. Lucky I didn't order the 4.1
I have a 2015 LS-M 4x4 Crew Cab

I make the 245x70x16 = 29.5 and the 285x75x16 = 32.8 so 32.8 / 29.5 x 3.7 = 4.11
One way to get the diameter of a metric tire is to multiply the width x the profile x 2 / 25.4 to get inches and add the rim dia.
245 x .7 x 2 / 25.4 + 16 = 29.504 etc. There are other ways but they will come up with the same answer if they are correct.

Thanks heaps oldlux. I was almost right just as well you sorted it out for me. I will look around for 4.1 gear set.
One more Q oldlux if I fit the 4.1 gear-set to suit the 32.8 tires for off road, and use the the STD 29.5 for on road would see any issues.
I have to add the DMAX and a loaded UEV490 off road camper the CGVM 4930Kg in your opinion would fitting the 4.1 gear set help.

Well for the first thing is the speedo will read about 11% higher than it would with the 32.8's on, It will make towing and breaking better with the lower gearing at that weight. Should be workable IMO but you will have to be the judge of that after all. Let us know how you go with it all ay?
