Power modules

I have a '05 120 diesel, however, I am looking to put in a power module and would value your collective opinions. I have researched this issue on the forum but have not come across the "Diesel Power" Chip. They are on the web for $990 delivered which is way better than DP Chip or DTronic at $1320 or $1500 respectively. They are fitted down from the ECU and make similar claims to the DP Chip.

What do you know about them?

IŽd take a TTE chip: http://www.tte.de/popup/TTE/cm_landcrui ... ncekit.htm

Thanks for the link but it seems to be only available for the D4D

If you look at the brochure it actually does cover both models. The older diesel gets an increase to 150kW and 405nm whilst the D-4D goes to 150kW and 470nm

Thanks Bomber,
I had another look but it doesn't list the 3.0 ltr as such just the D4D. If the first on the list is the older motor then it says that they can get 150 kw which is an +25% increase. The starting point would be 124kw. This is the starting point for the D4D not the older engine, not the 95kw that I have.

What do you think?

Have you got one of these or have you just found it on the web?

DirtTracker, I would suggest you have another look at the Dtronic. For three reasons...

1. Simple to install.
2. Simple to remove
3. You can resell it when you trade the car in. You can expect $800-$1000 dollars for them second hand at the moment.

Have you thought of locating a second hand one?

Cheers

Thanks Richard,
I am leaning towards DP Chip because it is adjustable when and if I put on an exhaust system. I have a snorkle at the moment, would consider a K&N filter. So have a possibility of adjustment through a laptop or via the presets appeals to me. My question though is about the Diesel Power chip as I have not heard mention of it in the forum. Have you heard of it?

dirttracker,

No I don't have one of these chips, I figure my D-4D has enough oomph for me at the moment. My impression is the chip being discussed is actually named the tte D-4D performance chip. It has nothing to do with the D-4D engine in the 120.

I also assumed that the lc-90 and lc120 was the older 3.0TD only because I saw the 343nm torque figure which matches the older diesel. Funny that it quotes it as having a standard power of 120kW. Seems a little confusing.

I'm with Richard, I would be looking at the Dtronic. I have a family member with this chip in his LC120 older diesel and it has been going strong for 3 years now (fitted from new).

Thanks Bomber,
It is getting alittle complicated trying to work out what various people are referring to. I am moving towards mainstream or popular chips to get to my solution. Thanks for your input.

Also....
The Dtronic (like the others) gives you around 120kw & 400Nm standard. This would be about the safe limit for the 1kz anyway. However you would still make a few gains simply by putting the exhaust on as the engine will be more efficient anyway.

You may get a few kw here & there by fine tunning to your particular engine & running gear, but I'm not sure its worthe all the extra effort.

In addition, when you got your quotes, did they all include installation? The Dtronic is the easiest to install, others you need to hack into the cables in the engine bay. That to me also sounds like your asking for reliabilty problems if the install is dodgy.

Anyway, as always I'd be interested in what you find & any info you may provide to sway me the other way....I'm also in the market for a power boost, but its on hold at the moment as its not a high priority.

Cheers

G'day,
Just remember if you go for a chip that is cheaper just because it is cheaper you may be asking for trouble. All the chips modify the fuel volume being added the more expensive units like the DPChip (Which I have) and the Dtronic also claim to adjust the injection timing. This change in injection timing is more critical to effectively producing more torque and power than just dumping more fuel in.

The older engine you speak of is the 1KZ-TE found in the 95 series and the earlier 120 series Prado's before they went to the D4D engine. I have the DPChip on my 95 series and it definitely increases the torque and the power by significant amounts. But it will also reduce the economy as you want to play with the extra power. It also makes the engine more responsive. A chip on its own is not the best solution either. I would suggest getting a full mandrel bent 2.5 or 3 inch exhaust system including the dump pipe from the back of the turbo. Doing this will give you definite power gains and allow for improved economy as well. A turbo diesel engine doesn't need back pressure so the more free flowing the exhaust is the better. A more free flowing entrance to the air filter will help too. Taking out the 180 degree bend on the Safari snorkel and running the intake straight to the air cleaner and fitting a free flowing K&N air filter will help a few percent as well.

There is, however, a down side to adding more fuel to a diesel engine. Unlike a petrol engine, adding fuel to a diesel will increase the EGT (Exhaust Gas Temperature). If too much additional fuel is added the EGT will climb to a level that will cause damage to the engine. The more expensive chips will take this into account and not overfuel the engine. The cheaper chips, as many will tell you, are only devices which are cheap to make but cost a small fortune, that increase the fuel volume by a set percentage, not a variable percentage across the rev range of the engine, and do not adjust fuel timing.

So in conclusion I would say go for one of these;
Dtronic, DPChip, Tunit (If you can get it, same as a DPChip) or Steinbauer (Bulky). There are others but I have not had discussions with anyone on them so I don't know what they are like. But these 4 I've listed are all quality units.

Regards,
D.T.
