Stienbouer chips.. Do they over fuel?

Mick,
there was a thread recently (and I can't remember where) about a fella with a D-max that had one fitted by the Isuzu dealer while the vehicle was under warranty,

One of the pistons had melted and Isuzu said no warranty. Fella said but your dealer fitted it. Isuzu came back and said yes you will have to take it up with them as we only warrant our product as we supplied it.

When the engine was inspected there was signs that the bores were being washed.

Mick I reckon that if you ring more horsepower out of an engine at some stage you or the next owner will pay for it. My thoughts only.

RA.

I have wanted to buy a chip for my 200 but keep seeing posts similar to what you refer to, albeit with a different engine. Lots of black smoke, trouble lights. While the Steinbouer seems to be one of the better ones, there always seems to be some issues with some users. Others of course are happy but maybe they haven't seen an issue yet... I have never been able to pin it down.

So, after years of analysing it to death I have decided an exhaust will be better and I have never seen anything other than positive reports about their effect on the engine. Obviously the performance increase is about half of a chip though. Maybe there is the clue right there.

Yes chips will over fuel at some point but not really a concern.

Your mates who are mechanics may be living in the dark ages.... washing oil of bores is from over fueling is a bit of a urban myth, any oil left in the bore above the oil ring will be washed or burnt of anyway in any engine.....if oil was left in the bore above the oil ring then the oil ring is worn and may lead to glazed bores.

A chip will give you way more bang for you bucks over an exhaust only, chips change the driving characteristics noticeably throughout the rev range.

Chips in most cases don't make an engine any less reliable, for starters manufacturers will not make an engine that is that close to it's reliability limits and secondly you may only use the maximum total power gain for less than 1% of your driving.... if the engine was under 100% load day in and day out then yes it may shorten your engine life but not by as much as you think.

Like anything to do with performance, maintenance has to be 100%.

Most linehaul B doubles will run maximum engine load around the 50-60% of the time, triple road trains around around 75%.

There are a lot of people who will may say different, sure..... show me the REAL data to back your claim and I'll believe you and don't use the old excuse the more power you have the shorter the engine life....

Your last sentence is a classic... if you don't need/want more power why didn't you buy a 2006 non turbo 100 series, you could of saved heaps of money.

I have 160k on my Hilux D4D, 80k of that with a chip. My mechanic has 300k on his Rodeo, 200k of it with a chip. Both vehicles well maintained with oil changes evey 5k and no problems or issues

I had a Steinbauer fitted to a Ssangyong Rexton and had no issues with it. The SB units don't increase fuel rail pressure like some chips. They operate by altering the timing of the injection. What I liked it, it was (is) the only unit on the market which monitored the throttle position and it has a time limit on Max power to. Sure, if you crank the adjustment to max then you can get black smoke on acceleration and heavy load. There was a comparison test and write up in 4X4 magazine about 4 years ago and whilst the SB didn't give the greatest increase, it did get the nod for the best overall performer.

A friend of mine had one fitted to a Prado. He thought the power wasn't coming on down low enough; spoke to the SB guys at one of the Melbourne caravan shows and the drag the laptop into the carpark and readjusted the setting - bingo one very happy customer.

hi mick , have a stienbouger fitted to my jeep commander (crd meredes motor) and is impressed that much that i will be fitting one to my new grand jeep when i recieve it next month. maybe some of the threads that bag it out, maybe the motors arent ready for extra power. ??
i tow a 3 tonne van and it goes everywhere and these nothing better when u need it the power is sitting there ready for you especially when you get into the sand dunes.
i have now done 70,000 km and i did not change my exhaust and dont need too.
tah chris

Mick,

"an unbelievable sufference"??? I thought that was actually the missus when she found out you'd bought it lol ;-)

I have written up the results on my 79 series ute after fitting a chip and adding a 3" exhaust 18 months ago, and they are outstanding. Having said that I did not opt for a straight "plug and play" fuel rail or fuel pulse type chip of which the steinbauer is one. Rather mine is integtrated into the fuel and tuning system of the vehicle and they spend a good amount of time on the dyno getting the settings right to ensure that you don't melt a hole through the piston of your valuable investement.

To my mind, the simple equation is this. Chip = more fuel. More fuel means greater heat in the motor and greater amount of exhaust gasses to be evacuated. If you go for a chip, you would also benefit from fitting a larger exhaust to assist in removing gas buildup. Having run the chip in my previous 3Lt/D Patrol, I would also consider fitting an EGT gauge at the same time. I'm pretty sure a lot of people don't realise just how much extra heat can be generated in the engine durng times of peak load and particularly when towing. It doesn't take long in the death zone to slag out the top of a piston!

The write up and power/torque increases achieved are near the bottom of the blog page below;

I have heard good stories about the Stienbauer module, However, I have run the cheaper (<$150 fleaBay variety) on several vehicles and had no problems. The trick is to go for a modest output increase with these...no overheating, seat of pants improvement in performance especially acceleration ad turbo lag, not rocket like but very adequate, smoother running and better fuel use. (about 1k/l per Scanguage)
If you want a rocket ship; buy one...or a good exhaust and chip combo.

G'day mick78
Is it a Stienbouer, or a stienbouger chip ? or Steinbauer chip? I'm a bit confused as to what you have as both are stated on your first few lines.
As far as I know Steinbauer chips do not raise/modify fuel pressure and are not connected to or control the rail pressure at any time. They say it doesn't?

Many people have a Steinbauer ( written on the box) chip and apart from a few having small troubles it seems like yours wasn't matched to the engine in the first place.
Generally chips which don't raise fuel rail pressure don't cause too many problems.
If you hold a door open longer or earlier it doesn't stress the door too much. injectors the same. If you have someone pudhing hard on the door before opening then it's a different story, ie higher pressures = shorter life. If it does 100,000km with a higher rail pressure chip before failure. it probably would do 200,000km with normal situation. So life is shorter despite what some argue.


Of course you can be overfuelling with too much quantity, when this is happening it immediately turns to smoke and should be rectified.

Can't see how it can be washing cylinder bores if burning correctly and not overfuelling.
You can't believe more than 10% of mechanics anyway, but which ones are they?

Generally most CRD engines benefit from a larger free flowing exhaust and it is the basis for any further mods. If it is then chipped the full benefit from the chip can be realized. Without the exhaust any mod can't really begin to show full benefit.
You can always eat more, but unless you can poop faster it isn't going to be of any great benefit and a feeling of uneasiness will most likely be felt. Engines have feelings too.

Read posts through and discard the irrelevant stuff.

Hi

I had the Steinbauer chip and Taipan exhaust put in my 2007 Prado diesel in 2010.

Prior to the purchase I spoke with the Steinbauer rep who advised that the chip does not work when in cruise control.

On several trips between Perth and Kalgoorlie since we noticed a decrease in fuel consumption with and without the van. During those trips the majority of the trip was using cruise control so I put the decrease in fuel consumption down to the exhaust.

I normally turn the cruise control off when going over a group of small hills when I get some surging or on the larger hills when the chip can assist.

We have had no problems to date and a very happy with our setup.
