Maybe the pictures on the website are better than the tuning box itself !

From my understanding is Bob, it fits in the cable feeding the airflow meter and in-line with the accelerator cable. And modified theCode from the ECU to the unit without re-mapping the ECU as is the usual. Have seen them a lot higher price than this. If it works i could do with one

Ah - David Thank You for your explaination, however the key word perhaps is "IF" it works and delivers the savings / benefits stated ?

Hello Bob,

In my opinion, such an external device cannot reprogram the ECU.

It just fools it by modifying some inputs, for example by lowering the temperature value of the air inlet.

If the ECU thinks the weather is very cold, it will inject more petrol. As a result the engine can actually be 10% more powerful (at least for usual temperatures, not for very cold weather).

With the risk of damaging the rest of the mechanics! (however 10% should still be within the standard safety margin)

Now, I don't see how such a device could improve the mileage.

You know, engineers work hard to adjust the engine parameters in order to achieve the best mileage for a given hardware !

I hope this device is doing much more than just fooling one sensor. If not, it would really be too expensive...

When i used my K&N filter i got a lot more power at the top end and a reduction at the bottom and that was only letting more air in but i must admit its not easy without a lot of air ducting to feed cool air in. So i can see an advantage in tricking the ECU but as Christophe says how good is it going to be. Having 18 inch wheels you need more acceleration at the bottom end at roundabouts. So interested to see if it works

Loads of similar all over eBay. Isn't it just a resister that fools the car into thinking it's warmer or colder than it should be so the car pumps more fuel in etc. Might give better performance in some conditions, but with higher emissions and higher wear and possible cold start issues etc.

If it were so simple to get a 10% economy and performance increase for £100, don't you think Toyota would snap them up in bulk, slap them on their latest models and beat the competition?

If it sounds too good to be true, it usually is.

Good Point ! your possibly right !

Id debate how well this worked, but actual programable ecus make a big difference. I spent a long time working with a TT tuner on my road bike and it made a big difference, on power, smoothness and MPG. I went from 108hp at the crank to 115 at the wheel, and now I can get about 140 miles to the tank when it was 130 previously, and its so much smoother with power delivery. The toruque/hp curve is so much smoother than it came out of the factory. Each engine is different and manufacturers cant spend the time doing each one, they just have to set general parameters to try and cover all bases. I can literally ride every where in 6th gear and not have to change down. Obviously how much difference it makes depends on the application. Im sure with the correct hardware and a good tuner/operator even the IQ could be made to behave better.

Hello Bob.
This was on a review forum a while back, and it explains what the "chip" is, and how it works.
It also mentions the amount of damage that it can cause.

"Having been a member of various car forums and been asked
whether these 'tuning chips' work a bazillion times by other members,
and after seeing how many are being listed on eBay, i thought it was
time to set the record straight on what they are, and the harm they can
do to your engine. Firstly, they neither chip or tune your engine - only
a proper ECU chip, mapped to suit your car with the correct
fuelling/air ratios can tune it (superchip, seb etc) and these are
usually 100+ pounds to buy and are a replacement EPROM for the board in
your cars ecu. They're NOT a 10p resistor available from any branch of
maplins or RS. So what does this resistor actually do? In a nutshell it
cons your ecu by sending it false information about the temperature of
the air going through the airflow meter or IAT sensor on your cars
engine. It basically makes the ecu think the air is much colder than it
actually is. The colder the air, the denser it becomes. Dense air (if my
physics is right) means that you're getting more oxygen per cubic
centimetre (CC) in the combustion chamber which makes the mixture of
fuel and air burn hotter, making a bigger bang and creating more power.
Its this information that is used by the ecu to adjust the amount of
fuel needed for the conditions its sensing, and proper running of the
engine. Right, thats the science bit out the way.

So whats the problem with the resistor 'chip' then?? Right.....with
one of these resistors fitted, your cars ecu recieves the air
temperature info via the resistor which, as said previously, is not an
accurate reading of the air temperature going into the throttle body.
Because of this, the ecu makes the fuel system of your vehicle deliver
fuel at a higher rate than the engine needs. Yes you might feel a small
improvement in power (although in some vehicles the opposite is
true) but too much or too little fuel is pretty serious as it can lead
to detonation, lumpy idle, bore wash, higher emissions, lower mpg and,
in extreme cases, even wrecked pistons!! Anyone whose ever had their car
in for repairs at a garage will know how costly in terms of
inconvenience and money this can be, and dont expect much help from the
seller, as the small print on the packaging will state that no liability
will be taken for damage caused from use of the product 😞

Please remember what your parents probably told you many
times - if something seems too good to be true it most probably is!!
There are no tuning mods that deliver 20+ BHP for a couple of
quid.....if it was that simple to gain horsepower from an otherwise
standard engine car manufacturers development costs would be a lot lower
and everyone would own a racing team 😉 Unfortunately there are also no
shortage of unscrupulous people who are only too happy to relieve you
of your hard earned money by promising the earth and delivering a
nightmare so research your subject before you buy.....

If you're serious about tuning your engine the best advice i
can give you is to go online and join a forum that covers your make and
model. This way you can speak to people who have already done it. They
will tell you what works and what doesn't, whats good value for money
and whats a con, and you'll meet friendly, like minded people as an
added bonus 🙂

Well thats my tuppence worth - hope reading this has been
of some usefulness to you. Please remember to mark it as helpful if it
has been 🙂

Buy smart, and remember........fire burns! 😛

Lucky."
 

The only way to attain what you require/desire, would be to have a full re-map of your ECU, which will cost upwards of £300
Also, if your car has a warranty on it, I would check with the warranty providers to see if a re-map affects the policy in any way.
You will also have to inform your vehicle insurers of the modification.

I hope this provides enough information for you.

[Grumpy Cabbie]

Or put it a simpler way;

If it looks too good to be true, it usually is :)

If Toyota could get an extra 20 bhp out of their little 3 cylinder 1.0 engine for £20, do you not think they'd do it?

[bobkneale]

Thanks for the above explanation much appreciated !

[Parts-King]

I would think this chip is for a Diesel version, as a chip for petrol models do not really exist, apart from the carp that does nothing for your car, which can be put in the category of magic fuel magnets and fairy supercharger dust

Howdy,

Its like you dudes dont get it...

All engines have a safety parameter and tolerances etc...

Toyota if needed could double the power output of this motor if they needed tomorrow. When you manufacture cars your biggest fight is to meet customer expectations while complying with your market compliance regulations in terms of emissions standards etc. So there is no point of making a car like this thats in the same emissions bracket as a Ford Focus RS or RS3 and so on.

In meeting class standards and competing with other manufacurers you end up in an awkward place of dudes in a forum debating on power gains on a car that was planned only to be a sleek Urban cruiser for mostly single people who likes to look sphisticated while heading to the coffee shop or late brunch on a Saturday.

It is what it is.... save your money just install a K&N and be content.
