Making the ECT button useful (1 Viewer)

[ThreeEyedBandit]

Edit: This wiring is for 93-94's. I'll look up 95+ wiring later on.



Here is a quickie that I did years ago to make the ECT button way more useful.

Effectively you take(de-pin) the B-L wire pin 19 on the 'B' connector, tape it up and set it aside.

Remove pin 14 on the same 'B' connector, the P-W and place it in the original cavity for the B-L(pin 19) wire removed above.

This allows you to leave it in the softer shift points in low range which is super useful in snow, and also select the 'low range' high revving map in high range for Sand and other street racing activities. Also is really useful to keep the 'high range' map active to save your neck in low range. One of the best things I have done for playing on super low traction floater snow.

street racing activities

Isn't "street racing" an oxymoron when it comes to our Land cruisers.

not when it's against other landcruisers.

This really happens down there???

Are you saying, besides being able to select different shift points by mashing the ect button, there is also preprogrammed low range/high range mapping that switches with the high/low lever? I pretty much mashed my ect button 18 months ago when I put on 37” tires and left it there no matter where the range selector is at and it works for me.

Yes, certainly is. We use to have ''Wednesday wagon races". 80s Subaru wagons, one block at a time, exhausts removed of course. Was lots of fun, and was never able to break the 25 mph speed limit... Scaring children and nuns kind of stuff

On my 93 and 94 the shift points are drastically different in low range. Holds the gears might longer than high range, and way higher than than with the stock 'power' map.

I would have to assume the 95+ vehicles have a similar map, but the wiring will be different since I recall they use a pcm, not a separate tcm and ecu

I don’t notice a difference with ect on or off in low range, but then again, I’m wheeling at that point and my attention is elsewhere. I’ve had 94 and now a 93. Both will shift into O/D in low range. I’ve read several times here that this won’t happen. I’ve also read that O/D is unobtainable until the trans is up to a certain temp, but mine will go into 4th immediately. I read a lot on mud and much of it is snazzy sounding bs.

 

[ThreeEyedBandit]

They will definitley go into O/D in low range, that sounds like someone not trying hard enough.

I'm not talking about having the ect mode on in low range, just being able to select the either the low range or high range maps via the stock ECT(pwr) button. Regardless of the which range you are in.

I wouldn't doubt the factory would disable power mode in low range, but the couple hundred rpm max you get is trumped by the couple thousand rpm you get in the low range map. So less noticable.

I couldn't agree more, most of the reason I spend less and less time on here.

I'm terrible at explain stuff, especially typing it on the internet's... I'll get a short video later explaining this

Well, for my purposes, the ect mode by itself brings rpms up enough to make a significant difference in acceleration. This, of course, is based on throttle position and duration of time it’s held there.

Gotcha. The biggest use I found is in the snow, allows the trans to shift at much lower revs and less harshly. Keeps the tires from spinning and allows momentum to be built as needed.

80s are deceptively slow.

A year or so ago I accidentally turned off my ECT button and thought I had a tank of bad gas or that something was wrong with the engine. After a some casual troubleshooting I realized it was off, turned it back on and it felt "normal" again.

Softer shift points in low range, especially from 1-2 would be nice though.

I'm running a '94. So does this mod basically keep soft shift points for both low range and high range, if ECT is not used and changes the shift points to the harder shift for both low & high if ECT is mashed? I'd love to have the softer shift in low range, especially 1 - 2!

Bingo! That is exactly how this works. All it takes is a small jewelers screwdriver to extract two pins, and stab one back in.

Do this while your in there and you will always be in power mode.

Absolutely! I take great pleasure in blowing the doors off a 200 series at the traffic lights

how is the safari set up? still on the fence but looking more likely I'll keep my lpg and turbo it with 5psi boost

yes. the trick, I have found is that you don't let the other guy know you are in a race. guaranteed success.

Awwww, come on!
That's like playing rock, paper, scissors by yourself, or taking your right hand out on a date!
