Yeah the SQL can only be done using the MUT 3. It is more thorough doing it with the the MUT 3 although you may notice it or not but the triton or pajero will carry out a minor SQL on their own. You can tell if its doing it it will make a funny sounding noise.
SQL has to be done on all tritons and even pajero with the common rail system. Due to the injectors being coded.
Another thing is the injectors have their own own coding and also have to be coded to the ECU otherwise they will run like crap. Can only be done with MUT 3 yet again.

New to this site and good to see everyones comments.
I have a MN GLR Man 4x4 and just had it back to the dealer because of the engine fuel knock is getting bad and the fuel economy is getting worse.
They told me that they had to reflash the memory and everything should be OK. As it was Friday at 5.00pm I drove off and the problem was exactly the same.
The vehicle has now had two reflashes and only has 9500km's on it. When it was new the fuel knock was only there during warm up and was never there after reaching operating temperature. Ran smooth and quiet for 2-3000km's and then got gradually worse. Now it is there all the time. Is this a sensor, injector or computer issue? and is there a good dealer in the Goulburn Canberra area that can fix this?

Much much quieter engine than a ML. Thats a definate!
However its seems to work a lot harder (revs faster/easier) and did sound 'pingy' compared to mine.
I have found fuel quality makes a huge diff (to pinging as well as economy) but this isnt the thread for this guys!
Ask your dealer to perform a SQL. (If they havent already) It definately has made my engine smoother running and possibly helped economy but i doubt that.. (2nd tank just started first showed better economy marginal but was tainted by some 'spirited' driving but I have so many changes I couldnt pin it on one thing anyway)
I am curious what the mechanics on here think about the statement that a SQL can help with economy... Given the ECU performs its own calibration when it feels the urge..
Chaser: Is a MUT3 SQL something you guys just do as a matter of course during a service or is it something done only when something like tappits are adjusted and/or the client complains about engine economy/surging etc?

I had a auto 3.2 paj the other day with the fuel thingy in the dash(forgot what its called), drove it up the road and back i think it was about 8.1-8.2 l/100. Performed sql and it droped to about 7.9-8 l/100, so they do make a difference.
