I am wondering if power chips really do work for new common rail turbo deisel engines as they are already quite powerful and fuel effiecient. By nature and natural desgin i would have thought you couldn't get much more power or turque out of this type of engine.

Has anyone put a power chip in a new turbo deisel engine that is common rail set up and noticed a real genuine difference. Especially in regards to towing a caravan or boat.

I have also been told that if you do power chip this type of engine you MUST upgrade your exhaust system to a better free flow with greater capacity to compensate for the increased power flow.

Any body in the know. Thanks T&S.

Yes they are, in fact they can increase your power and torque by 30%, Tunit have an adjustable plug in unit, Unichip also have a good unit.

There are also places you can have your ECU re-mapped, these are normally the cheapest of the power upgrades and have more options to give more power.

Other options are, a larger intercooler, 3" mandrel bend exhaust, changing the centre muffler (do not remove, only replace) silicon intercooler hoses, the list goes on.

One of the best power upgrades is;

ECU remap or plug in unit
Bigger intercooler with Silicon hoses
3" exhaust with centre muffler upgrade

They sure do, but what is usually the case is you modify the motor in some way, like bigger intercooler and exhaut system, then add the chip, and it increases fuel and boost, to give you better performance. Be very careful, as there are chips and chips....major brands are safest bet.

Hi Gronk, did you notice any fuel economy improvement or are you more into the performance side....touring/towing etc. ..how long have you had it on....local distributors etc?????....ta..silverback

All these things increase power by putting in more diesel !!!
But the increased torque offsets this a bit, if you have a light right foot !!

I have had mine fitted to a CRDI Terracan for approx 1 1/2 years......but I also have mine wound up a bit more than the standard setting they come with..

No local distributors....but feel free to email TDC and ask any questions..

Mine is using approx 1/2 to 1 extra litres per hundred K's....but its also wound up a bit more as well..

I fitted one from this crowd:

Site Link

Their website says: 07 V8 Landcruiser single and twin turbo plug in tuners selling strong, approx 35kw & 130nm of extra stump pulling power $990. Dont pay more for lower quality tuners that dont get the results.

35kW is 23%. I got 12%. It was a waste of money. I took it off to see if I could tell the difference, nothing, ON or OFF. I discussed exhaust systems with the owner in Brisbane too and he said they were not necessary. His chip was all I needed.

There are some informative posts on LCOOL:

http://www.lcool.org/forum/index.php

Just do a search. It seems to me that most of these devices inject more fuel and that's not what I wanted.

cheers

I thought about chipping my CRD but the research I did kept coming back to pouring more diesel into the engine to do it which = increased fuel consumption.
So I had a talk to a fellow I know who runs an exhaust business and he reckoned he could get me a 5 - 10% increase in power by playing around with the exhaust system.
The OEM exhaust is fairly well baffled and his view was that by opening up the exhaust he'd get the turbo coming in quicker, virtually eliminate any turbo lag and excessive back pressure which would be robbing the engine to some degree of power by using some of it to push gases through the restrictive OEM exhaust.
I decided to give it a go so we played around with 6 differently configured Mercury mufflers. I didn't know which one I was trying, he just gave them a number and I tested.
Surprisingly there was a difference in engine performance caused by the back pressure created by the angle the pipe went through the muffler.
Anyway I settled on the muffler that had around a 3 degree angle off straight. There wasn't any noticeable difference between dead straight but the 3 degree angle gave a deeper note.
I haven't had the engine dyno tested but there is definitely a noticeable increase in power and torque. I've also fitted a K&N Air Filter to get improved air flow.
Fuel consumption has reduced from 10.2l/100k at 100kph on average to 9.5 on average.
The jeep techs who service my vehicle agree that there has been improved performance from the engine of around 5%.
The exhaust guy reckons I've chipped the engine without "chipping" it.
Anyway for what it's worth thought I'd let you know.

Cooroy Exhaust Centre Graham. Fairly small shop, doesn't charge the earth and really spends some time getting the note and performance to your liking. One of my son's visited over xmas and was so impressed with what they did to mine he got a system fitted to his BMW 318i with the same result but being young fellow his is a tad louder then mine!!!

I have the V6 3.0l Merc Engine, it's an awesome engine. Jeep have done a great job of matching the gearbox to this engine.

My vehicle's a 2007 Grand Laredo WH series

Geri,
If you do decide to change your muffler I would recommend you trialing several different styles similar to what happened when I did mine. Some mufflers have an "s" bend some are straight through with the pipe offset at different angles, also the dia of the pipe will make a difference. The note will change as will performance. As an example we tried one that he uses on V8's to get that deep growl. On this particular muffler even though you could see straight through the muffler there was no straight through pipe instead it was baffled when I tried this style it created turbo lag.
If you do go ahead I would be interested to hear how you get on.

Would suggest a Safari chip as its programable to each individual engine via a laptop software program

We have a DP chip fitted to our Hilux and the improvement is very noticable.

The Hilux weighs 2700Kgs and sitting on 110Kph we get about 10 to 11 L /100k.

With the Trak Shak on the back weighing 1400Kgs we get between 12.5 to 14 L/100k.

Yes they do work and are worth it.

It's not about speed but easy of driving, before torque came in around 2300rpm and stayed flat until 4200rpm now it comes in strong at 1400rpm and stays until 4500rpm.

Why not try a DP chip and if you don't like it take it back and get a refund (they offer it on there web site).

But a warning you will become addicted to it.

Regards Richard

Hi AZP777,Agree 100% with Olcoolone,also have a DP Chip fitted to my Terracan and the increase in pure grunt is amazing,also have a complete 3"exhaust system.Go ahead and do yourself a favour.Cheers Snake and Josie

Silverback, No real noticeable difference when towing but a bit heavier around town as I have a heavy foot now from the lights especially if a Tojo or those other brands are alongside,which is not for long.The look on their faces is worth any extra juice.Cheers Snake and Josie

Ok niave question.
I have got the free software for the OBD2 compliant engine in the 2002 Jack and it would appear that you can do some reprogramming of the ECU for more power/ better economy. The catch is that I have yet to get the OBD2 to USB lead, if I could find the pinouts I could make one, my research continues. I would have thought though from a purely high school physics stand point that if you want more out you have to put more in and I'm sckeptical that you can get say 30% extra for no extra fuel burned but then most vehicles would be factory preset to some manufacturers optimum so some tweaking may give you some advantage but the cost of these upgrade chips is I suspect exponentially larger than any realistic gain unless you want to throw more coal into the fire box.
