Common Rail Diesel Tuning

[hsv364]

Guys ..

Just traided in the Triton GLX-R on a brand new Toyota Prado GXL.
Now im looking at having it tuned and upgrading the exhaust ! Ive done some reserch and from what i can find is that the STEINBAUER tune box is one of the better products on the market ..

www.steinbauer.com.au


Was hoping to here some feed back from what other forum members have used / ran in the past on there rigs being good or bad feedback.

As for the exhaust system i have boiled it down to two

DPI Diesel power chip from Berrima Diesels are pretty good, factor in a new exhaust to get the most of the chip, and enjoy the wall of torque and better fuel economy.

[kayman]

I've driven a Prado with e Diesel Power chip in it... its now on the list of things to put on my Hilux with a 3 inch turbo back exhaust.

[F6 381]

Mate check out www.chipit.com.au as they can actually tune your car to your needs on the dyno. Nothing wrong with Steinbauer as it is better than DP Chip.

[trialweis]

Mate check out the humex exhaust systems I have one fitted on my 07 t/d hilux 3inch from the turbo right through sounds awesome along with the Steinbauer chip and TJM Snorkel made a huge difference in power also improved fuel economy

[JezzaB]

Go the DP chip and taipan exhaust. DP Chip are also the only ones that will warrant your engine with the chip

might have to meet up sunday at the cruise and have a yarn about turbo diesel hiluxes!

[GMHVNSS]

DP chip and Manta 3" turbo back for the win, a good website for info on the 120 and 150 series prado's is pradopoint.com.au

[duke5700]

Anything for the new Isuzu common rail utes?

[trialweis]

might have to meet up sunday at the cruise and have a yarn about turbo diesel hiluxes!

No worries mate ,
I'll be driving the stock as a rock fusion VZ Monaro!!


Personally I have herd a few bad reports about the DP chip going into limp mode.
Never had a issue with the Steinbauer.

Clinton,


I do many deisels,stick with stienbuar if you want your engine to last the technology is awsome,it does fueling thru injector pulse rather then rail pressure like some nasty boxes circulating.As far as exhaust goes your on the money for the 2 you named,i have used both,both are of good quality,on my =cruiser i have the beaudesert stainless.fi you need more info feel free to contact me :)


regards sonny

[Sonnymad]

Go the DP chip and taipan exhaust. DP Chip are also the only ones that will warrant your engine with the chip

Read the warranty fine print jezza it gets complicated...

[MARRA]

Old Man has a Beaudesert Pipe on his 200Series, very happy with the fittment and note. Would recommend.

[JezzaB]

Read the warranty fine print jezza it gets complicated...

As were are a DP chip dealer and i have and installed 100s of chips, i have read it many many times, its very simple. We sell and install usually 2-3 a week with 0 engine failures. The workshop has been installing them for over 5 years.

[kayman]

Does the DP chip work via increased rail pressure or by increased pulse, I was under the impression it was via increased pulse.

[JezzaB]

Does the DP chip work via increased rail pressure or by increased pulse, I was under the impression it was via increased pulse.

Usually piggy backs into the rail pressure sensor. So increases the rail pressure.

[Sonnymad]

Jezza,


Interesting,so whats your veiw on increasing rail pressure to silly amounts jezza ?

[Martin_D]

Piggybacks.......stick clear if you can. All of them are fudging signals :)
There is very little in the way of direct programming for the Denso CPU in the Toyota Clint so you may need a sensor fudger. How about one of ol mate Peter Luxon APS Safari things, they have got a good name. The reality is that all of the piggyback signal benders will increase rail pressure at some point of the engines operation cycle, but CRD engines have upwards of 30,000psi fuel pressure in the first place, so its no biggie :cool:

Remember - one key objective - being a diesel, its not going till there's coal coming out the stacks :bow:

[hsv364]

Thanks for all the feedback gents .. Much appreciated :goodjob:

Its a great forum for Prado's, and you will get some feedback straight from the horses mouth.
Many discussions on this subject.
I run a Beaudesert exhaust on my Prado. its made a massive difference to the point where ive decided to not worry about the chip. A lot more torque allround, the Turbo spools up 300 rpm earlier and about 150 kms more out of the duel tanks.

I would be going exhaust first and then go from there. Also found a KN filter also made a huge difference.

Cheers john

[drbob]

Yes.
Pm me if you like,I can help you out.

Slight hiccup today when going to order exhaust

Tiapan only have a exhaust done for a 3 door 150 series prado .. Havent manufactured a system for a 5 door yet :bawl:

Beaudesert only do a 2 3/4'' exhaust for this model not 3'' which i want :bawl:

Humex dont have a exhaust manufactured for this model yet :bawl:

Looks like a custom fab job maybe ?

[Tre-Cool]

surely there isnt anything special about the exhausts that you couldnt have made up/custom?

Whats the cost of the exhausts allready mentioned? are they $$$ compared to say a commodore exhaust?

Similar model car with these brands mentioned above Dave vary in price from $1135- $1580 in mild steel 3” Mandrel Bent , Ceramic Coated Dump Pipe with 200 cell catalytic converter, flex bellows, Gen 2 vortex muffler and rear resonator.

I just wanted a of the shelf job to bolt up myself mate along with a plug and play tune and filter ... something simple and easy for a change !!

There is very little gain(if any) on this engine between 2 3/4 and 3" according to the experts apart from a 3" being slightly noisier and more likely to drone.
Very similar comparison to running a 2 1/2" vs 3" on a VE.
The only time i would imagine it would make a difference would be if you went larger in the turbo.
The biggest performance gains are at the dump pipe off the turbo and the mandrel bending vs crush bending, and obviously the larger diameter pipe.
When i changed my exhaust i could not believe how small the internal diameter was on the oem dump pipe.

[GMHVNSS]

Call Manta in Belmont, they do a 3" system.

[michaels1v8]

If you change your mind and decide to get someone to do the work on your truck make sure you check out United Fuel Injection on great eastern highway.

I had my dad's patrol done there and can't fault their work.

turbo modifications, all exhaust including dump pipe and tuned in a day.

I had forgotten to mention the patrol has had a 900mm extension in the chassis but they were very accommodating and organised the catback to be modified that very day (as I was leaving town the next day) without any dramas . :goodjob:

Give them a call for some advice as they seem to know their stuff. They won't bullsh&t you either.

Cheers

Do you have a vid of the beaudesert exhaust note, i've tried finding them on youtube, but only come up with the spiel about the company!

[hsv364]

Thanks for the info guys ....

Plenty leads for me to go check out ! :goodjob:

[duke5700]

I have been trying to do some research on "chipping" my Isuzu D-Max..

Came across this.. Obviously its an advertisement flogging there own product. I think from my perspective a ECU flash is the norm IE just the a LS based commodore.. Secondly I would go rail pressure and thirdly injector silly buggers.

Anyone chime in with more info.. only thing I know about diesels I learnt on headers and tractors and pulling ball bearing out of wastegate lines because the cocky wanted the gear to go faster.. :confused:

LIFTING THE LID ON DIESEL PERFORMANCE


TECH SHEET: - POWERING UP YOUR DIESEL

We often get asked about the method of generating extra power from diesel engines.

This data sheet answers these questions.
There is only 1 way to get more power from any motor, be it petrol or diesel … put in more fuel.
In a diesel, there are three ways to deliver more diesel fuel.
1) Injector Signal Interception
2) Control the Fuel Pump
3) Re-flash the OEM Engine Management System, or EMS for short


1) Injector Signal Interception:-
In this method, you intercept the injector signal or pulse. The signal in technical terms is called pulse width modulation. In basic terms the signal controls the opening point, open by “X” amount and closing point.
This increased duration and larger orifice allows more fuel to be injected. This is an extremely accurate method of controlling fuel flow into the combustion chamber utilising the engine designers/builders original EMS.
By intercepting and manipulating the injector signal you can make signal longer thus making the injector close later and you can increase the signal strength thus lifting the “pintle” up higher to make the injection port or orifice larger. Problem here is:
You cannot start injection earlier unless the module takes a “guess” at when the signal is going to occur and try to anticipating what it should do with the start time of the signal. The estimate may, of course, be wrong because you the driver may have changed the throttle position, or the engine go through some other change (ie higher/lower boost) so that injection cycle will not be what the OEM ECU is needed. Most Injector signal interceptors therefore do not manipulate earlier start times.
Problem with delaying the close time or close point is that the combustions can be almost over and the extra fuel being injected after the fact is MAINLY wasted. I am talking here about when the OEM ECU have also extended the close time. This would be a doubling of that extension effectively making it TOO LONG.
The real benefit is in controlling the injector orifice size with a little extension of injection timing at the end.
On the whole this is a good means of adding more fuel and therefore more power whilst having some limitations on fuel delivery.

2) Control the Fuel Pump:-
With the second option you intercept a signal to the ECU. With this intercepted and manipulated signal the OEM EMS then controls the fuel pump to request more pressure. The factory EMS asks for more pressure and then the OEM EMS controls injector timing to suit the new parameters. This method works very well since the OEM EMS is still in full control of the fuel injection. The signal to the EMS is also undetectable.
No problems exist here EXCEPT that you do ask the fuel pump to work harder. If the fuel pump is up to factory spec (ie has no defects) then there are no problems. If the car has a pump that is a bit off factory specs (ie some line worker had the flu and scratched the motor winding or the fuel pump has a bearing that has more fiction thus slowing it down or any other possible defect) then the fuel pump will fail sooner than what it would have if the Chip was not installed … possibly out of warranty (happy little manufacturer, unhappy customer). If the car is in warranty, you can simply unplug the Chip and take it back for a warranty replacement where you would receive, hopefully a new pump that is WITHIN specification.
No one will be any wiser as, as already mentioned, the OEM scan tools cannot detect the Chip or detect that a Chip was on the vehicle.
A failed pump is the risk with this MOD. Other than that this method of increasing fuel delivery and power is great and is well respected in the wider performance industry. To back this up, some OEMs performance arms like Toyota Racing Developments have come out with their own versions of Chips and provide full factory warranty, thus confirming the Chips validity.

3) Re-flashing the OEM EMS or Reprogramming the entire EMS:-
After-market EMS’ exist for this reason alone. Some OEM EMS’ have also had their code “cracked” allowing smart software developers, like ECUTEK, to re-flash the OEM EMS settings or maps.
It’s a VERY GOOD way of making more power however there are some issues that are too hard for HARD CORE vehicle owners or performance developers to accept. We are one of them.
Here are the issues. Firstly, the EMS re-flash is permanent addition to the OEM EMS. It can only be removed via propriety software which is nearly always only available from the place that first uploaded the re-flashed map. To add or, change or remove the new “tune” will cost you the consumer time and extra money.
As a common run-of-the-mill example: When you need to have your vehicle inspected by the Dealer or the vehicle manufacture, they are able discover the non standard program placed within their computer and flag your vehicle as having a re-flash and may dismiss any present or future engine or drive-train warranty claim you may. This will leave you up the proverbial creek holding the proverbial bag. Any drive-train faults or failures could cost you many thousands of dollars! To save your bacon, you will need to pay for the re-flash to be removed by the original supplier and pay for the re-flash to be reinstalled after leaving the Dealer. Also, if the Dealer re-flashes the OEM computer you LOSE the re-flash and you need to again visit the supplier or the re-flash or ANOTHER go. (ie more $$$)
Remember, this is not the case with the first two options above.
Re-flash type companies now “LOCK” the computer so that EVEN THE DEALER CANNOT OVERWRITE IT with a new factory update!!! They say that if you want to unlock the EMS, just take it back to the flash installer and pay a “small fee”. I bet the “small fee” is around $100.00 or more.
So after the OEM has overwritten an update (ie for the air conditioning or DPF or anti lock brakes etc) you need to take it back to the flash installer and again pay a “small fee” !
If they ever come out with a free Re-flash replacement policy, you would still need to get your vehicle to the installer!
Consider this: You are at the “back of Bourke” your factory computer fails or is playing up or the air-conditioning is not working, or the PDF light illuminates and you need the dealer to look at the vehicle.
This is the process if the re-flash is LOCKED:
Remove the OEM computer. Express post it to the flash installer for unlocking and to have the original factory stock tune installed. Have the stock computer mailed back (all at your cost) and reinstall it. After the Dealer has updated or fixed any EMS problem you then drive out WITHOUT a flashed EMS and start the mail back process again to obtain a re-flashed computer all the while having the vehicle off the road because you don’t have a computer.
This is the process if the re-flash is UNLOCKED if you don’t want the dealer to know you have a re-flash.
Remove the OEM computer. Express post the computer back to the flash installer to place the original factory tune in the factory computer. Have the computer mailed back (all at your cost) and reinstall it. After the Dealer has updated or fixed the EMS problem you then drive out WITHOUT a flashed EMS. Then park your vehicle somewhere whilst you send the computer to get the re-flash re-flashed!!!
This is the process if the re-flash is UNLOCKED and you forget about the re-flash or just cannot be bothered anymore.
Drive the vehicle to Dealer. Have Dealer berate you about the modification and threaten to void your warranty. Dealer overwrites the re-flash and you drive out with a factory tune! For these reasons we feel you are much better off with an interceptor style Power Mod … of any brand.
A little about our higher end Performance Chips.
All “SMART” performance Chips should allow full laptop tunability and allow variable ranges to be added at any point, at any rev range. Low end Chips will only vary values by a fixed amount by use of an inline variable resistor. We have seen very high price tags on some of these Chips which try to convince buyers that it MUST be a good Chip because of the price. This is not the case and for a long time well known companies have ripped huge profits from consumers for these cheap nasty rip offs.
All Chips that plug into the common rail sensor change the same signal. Because a Chip plugs into the common rail sensor it does not mean they do the same job. Some will use the variable resistor method mentioned above and one brand even has the variable resistor effect the idle signal as well .
Again, top end Chips will be fully programmable via laptop and have individual cells to adjust.
Why put out the info above?
We believe that by telling the truth people will appreciate it and shop wiser.
If you have a good product at a reasonable price people will buy it.
What is happening now, is people are seeing that the price of chips on the market is not reasonable. If you can buy a Performance Chip that does the very same thing (and even more with better quality and features), then why pay double!!!
Sooner or later people will need to explain why they are SO expensive.
We believe there is no need to con others about a product and so we tell the story AS IT IS and are on record about the FULL capabilities of our Chips.
We believe you don’t have to BS customers to get business. Some will buy one brand and some will buy the other brand. THAT’S THE FREE MARKET CONCEPT.

Our Chips provide features that others don’t (like MAP emulation, various output to drive other systems ie Intercooler Water Spray, LPG or Petrol Injection Systems and other outputs such as to allow EGR blanking.
The Chip It Performance Module also allows the factory turbo to make more boost (+4PSI) without the OEM Computer throwing a wobbly.
All these features in one module certainly make people take notice let me tell you.
With the above information we will undoubtedly cause some in opposition to be upset with the facts being made public however we trust that the information being in the PUBLIC ARENA will make most happy.

[ADAM 26]

dont put a muffler on a turbo diesel, just run 3 inch pipe, they sound tuff as, get the whistle out the pipe from the turbo.

just be carefull about how much fuel you put in the tune, we turned up the fuel in my 100 series and put a bigger turbo on it, it went really well, untill it went bang!

[BackyardSpecial]

Have you had a look at LPG /Diesel old man had it installed on his Prado ond is currently towing a 2200kg van and using only 12l/100km diesel.
Also more power and when the gas runs out it reverts back to Diesel only.
He has worked it out at a 30% gain.

No issues with the "Chip-It" module in my diesel chugging BT50.....

Locally supported too.

What sort of improvement did you get in fuel economy and power? wHAT OTHER MODS?

[6LtrLimo]

What sort of improvement did you get in fuel economy and power? wHAT OTHER MODS?

I wanted to do this in a few steps to truly measure the worth of the product.

Bearing in mind the BT50 has about 5000km on the clock.

Step #1 - Chip-It module install only.
No dyno runs to truly measure power, and I would imagine the engine is still quite tight being so low in km's.
Seat of the pants dyno resulted in a considerable improvement to torque.
Power increase is noticable but not mindblowing.
Prior to install, economy was averaging low to mid 8ltrs/100km
After install, low 9's.
Numbers are coming from the ScanGaugeII that is plugged into ODBII port.
Analysis is also being made on the same daily commute to/from work using BP Ultimate Diesel at all times.
"APPLES FOR APPLES" as they say.

Step #2 - Add Safari Snorkle and/or K&N Filter
Snorkle will be fitted early in the new year and Ill trial the K&N filter.
There is some speculation that the K&N filter is substandard compared to the OEM paper filter.

Step #3 - Add turbo back exhaust system TBA

[BEARWOOD]

Good idea what you are doing so keep us updated. What have you heard about the K&N filter to make you think it wont be up to scratch? Did you notice much difference in power/torque before turbo kicks in? I find the Navara D40 a little annoying under 18/1900rpm where there is a lack of anything to get you going and hoping to fix this somehow.

The torque improvement is "from the basement"

Regarding the K&N filters, Ive spoken to some knowledgable industry stalwarts and they have indicated that the particulate capture and air flow improvements are negligable in "on road only" applications.

I can only take there word for it as I am without a vast technical background in this field.

Alas, the price (and availability) of a K&N filter to suit the 2010 BT-50 (which means you end up with a Ford Ranger part #) versus the cost of the OEM piece is worlds apart.
Essentially, the K&N filter is approx. 18 times more expensive than the OEM piece.
In the long run, I may not keep the BT-50 long enough to do 18 air filter replacements.

[fatas]

guys before crashed my 2009 colorado i fitted a K&N and i can say what a improvment !!! cost $98 from Rocket better boost from low down , can hear the turbo working and better fuel economy was going to do a 3'' system but now need to wait to see if they write it off :vpo:

Hi guys, just digging up old thread here but my brother has got a new ranger - same as BT's i belive.? 6LtrLimo have you done your exhaust yet and whats the staus pls buddy? cheers.
