Dtronic? Does it overstress the engine?

soo.....the question begs to be asked....

if the engine is made to run more efficiantly by nissan, than why the blue blazes do nissan detune the engine for us???????

What you need to understand first is, the engine is tuned to suit emissions laws first, not power first, so this means we get engines which run very lean down low to fit into emissions laws, then richen once over 2500 odd rpm, over rich even, to compensate for the low down lean out, and this is where an economy improvement can come from with something such as a dtronic, the rest of the economy improvement normally comes from not having to use as much right pedal to do the same thing once the engine makes more power.

Now most of our 4wd diesel engines are made to meet Euro 3 emissions, which we dont have here, but because Aus is such a small dot on most manufacturers radars as far as sales go, we get what they send us, so we dont always get our own Aus tune version etc.

This is where dtronic helps improve performance and economy when not needing to meet emissions laws.

There is a long, but good article here on the subject

diesel performance chips etc

The 4.2TDI's are run fuel rich the whole way...When the powerup was done to my truck, the actually leaned it back somewhat even though boost was up.

It is also, for $1400 odd dollars one of the best acessories you will add to the car, because you get to use, and enjoy it every time you drive it.

Interesting concept Chris,
"Remember those figures quoted are at the flywheel, like every quotation, they are also inflated. "

Is this your opinion, or do you have data to back up this claim?

Absolutely my opinion. But go and drive a TD6 and I guarantee they do not have 114 kw at the flywheel. Actually, is also backed up by pre dyno report before powerup.

Ok,
your first statement seemed to be more a dig at the dtronics claim of power output, not the vehicle manufacturer itself.

Nope, just Nissans inflated power ratings ie. 114 or 116kw. Same with the old 4.2 TD42's in the GQ's as well.

I wouldn't worry about the dealers. I've loaned my chip to my local dealer to try out and they too are impressed. They've also had warranty cliams on motors with chips that Nissan have honoured.

Great piece of gear that makes sooooo much improvement.

They cant detect it even when its fitted with diagnostic gear, and by looking to see if it has one is the only way they will know, if you dont spend 10 minutes removing it first.
