Chip Tuning Box?

[Big Kev]

Scott.....if fitted as standard, and IMPROPERLY used (i.e. full pelt all the time), mpg would suffer, and so would sales because of it. Pure commercial sense.....if the extra power is there, we will use it.....then moan about the fuel figures.

PROPERLY used, it can definitely yield 4-6 mpg extra, and the overtaking flexibility and wee bit more engine flexibility and pleasurable driving experience is really quite obvious. Mixing both proper and improper like I did was great fun......Astra Boy was left looking daft on more than one occasion, then on long journeys mpg improved noticably.

Ahhhh. That makes sense. Always wondered if there was a catch. Thanks. I'll give it a few months and then have a look at getting one.

Well I've had my chip kit for three weeks now and the difference is amazing.
Lots more torque,especially from 2-3k rpm.
As Kev says your mpg will drop if you floor it..BUT if you take it steady keeping to around 1500rpm (which still gives you plenty of power in reserve ) then you will definately see an improvement.
My MPG has gone from 28 to 37,which admittedly is partly due to the warmer weather...I havnt even used it on an M'way yet,where I'm told it really shows its worth.

Ah. a chip kit.... I'd love to try one in my motor... So... Kingo.. I have a proposal for you...

We are driving 5000 miles in the summer, to Portugal and back. Our fuel consumption should be the same each way. Gees a loan of a chip kit and i'll try it to prove what difference it really makes to the consumption. I'll use it one way and not the other and see what happens??? Go on.... you know you want to!

I think another reason for Toyota not fitting or offering a higher state of tune is it would not allow the engines to pass emissions tests which are taken across the rev range and the loading of the engine at all revs ..

If you do the mileage these kits are a must have.. The extra power and driveabilty are a huge bonus !

Hi

I'm new to the club. I got myself a 2004 2.0 D4D Rav4. I was looking to boost the performance so I contacted Lindop but they told me that they no longer supply boxes for anything older than 2006.

Would you guys recommend any other box that I should consider?

Thanks

I'm trying to get me head round how you can get a big fuel saving on Toyota's diesel engine, if you are only putting a chip in circuit are you fooling the ECU into injecting less fuel, does this not make it run hotter and produce more NOX gases, this would then make the EGR valve come in more, this would then let burnt exhaust gases back into the engine intake system making it run worse, I was severly told off by memebrs on this site for suggesting blanking off the EGR valve because it would upset the running and Mr Toyota knew best, how can making it run weaker make things better, Blanking off the EGR valve is free it runs better and uses less fuel, but yes you do stick a bit of NOX into the sky, but making it run leaner weaker is even worse, manufacturers have made diesels run meaner, cleaner and use less fuel becuase they run hotter but the down side is more NOX, so they have to use a EGR valve to stop the NOX, so making more NOX gases won't save much fuel maybe I'm wrong, I could try a tuning chip but seems a waste of cash...

The cheap and cheerful chip kits do just that, they are a set of cheap resistors that cheat the engine into thinking it is running cold, and permanently overfuel the car. There are thousands of those on the market, made and imported from China and the far east. They are a waste of time and should be avoided at all costs

Decent kits like ours will or should be made to a standard such as TUV, and be multi channel with at least two connections to boost and fuel pressure sensors, some will also have a live data RPM connection too.

To say you get "big" fuel savings is misleading, it has to be taken in context. Most of my customers get between 3 and 6 MPG better consumption from their cars, which for some may be more than a 10% saving. We make no specific claims over MPG as it so much depends on how you drive and the type of driving you do, but like I say, anecdotally, our customers say a saving of between 3 and 6 MPG. This is achieved by having a much improved torque, anywhere between 50 and 90 NM in our kits. With improved torque, you are not up and down the gearbox all the time, and you are able to make smaller throttle pedal inputs with the improved power, the upside is better MPG and a much smoother power delivery right through the rev band up to max torque

Hi ajdath.

the tuning chip in your shortcut/link plugs in series with the fuel pressure/rail all this kit than do is increase or decrease pressure no doubt you may get a bit of extra power if you inject more fuel in, but where will the extral air come from, so the increase will be small. and if you want to use less fuel which might just happen, but it can only be achieved with less power becuase you will be running a leaner mixture which will cause the it to run hot meaning the EGR valve will kick in to cool the mixture down, even Toyota has not managed perpetual motion so I can't see a tuning chip manufacturer but please keep me informed.... and on another note, keep your eye on your DPF filter sticking more fuel in and running rich will probably cause more soot, who knows.....

[firemac]

I cannot comment on chip express but I had Kingo's kit on our previous 4.3 2.2 automatic and it worked very well. I carried out B2B consumption checks (and didn't simply depend upon the OBC) and during the time I had the car, mpg went from 31 to 36 average; that's a 16% improvement. In my case it gave pay-back on the kit's cost in just over a year.

In addition, the engine ran more smoothly and torque was noticeably improved. The deciding factor for me was the fact that, although it wasn't a Toyota-approved fitting (no chip kit is, by any manufacturer) it came with a Toyota dealer's de-facto reccomendation.

Tunit is another company that has had good feedback in the past.

I would be very interested in which one you try, if it's not the Lindon one.

[the fox]

Followed the link to chipexpress, it basically goes in between the fuel pressure sensor/rail all this kit can do is inject more fuel into the engine to make it run richer can't see you getting much extra power without a bit of extra oxygen (it back to basics), for the amount of extra fuel you will burn it would be a waste of cash , buy a faster vehicle

Although I was more than happy with the Lindop kit and would use it again, I always have the niggling thought in the back of my mind that says that if a manufacturer wanted better economy/performance/refinement, he would have tuned the engine to the same level that the after-market kits produce. After all, these things sell cars.

Because they don't, you can't help but worry that these kits are pushing the engine beyond it's design limits with possibly expensive results......

[the fox]

you are correct the manufacturer can only make a compromise, it's either more power or more economy, thats why you can buy a 136,150 or a 180 bhp, Rav4. you can't make 180bhp without using more fuel it does not work, but when manufacturers made diesels more economical by making them run leaner it made them run hotter which is better for economy, but they then produced NOX gases they then had to reduce by law. the only cheap way was to use a EGR system, all new trucks have then fitted, but the downside is, it reduces the heat thus reducing the power/economy, by blanking off this system you get better economy/power all the time, it cost nothing to do just a bit of old metal, your Rav4 will run cleaner, you can visibly see the differenc eless smoke under hard throttle, buying an expensive chip is not the way forward, if Toyota could make the Rav4 use less fuel and produce either 136,150 or even 180 bhp they would????
