Firstly, check that the body of the device - metal, is tight to the 'T' piece - plastic, (tighten with a 19 mm spanner).

Then locate a suitable vacuum servo/breather hose to the inlet manifold - see the diagram on the right..

 

Here is a picture with the various components marked which will help some of you with locating the relevant parts and hoses in your engine - if it's too small to see properly simply click on the picture for an enlarged version and when you are finished click the 'Back' button on your browser (this applies to nearly all the pictures on the site).

Here are some pictures of the device fitted to a number of cars - see also the illustrated Topbuzz fitting instructions by clicking here - there are many more examples which can be accessed through the 'Cars & Fitting' page by clicking on the name of the car. In all cases an expanded picture can be obtained by clicking on the picture and then clicking 'Back' on your Web browser to return to the main page.

Some carburettor cars are more easily fitted when using a template (pictured right) which is available for most SU Carburettors - click here for details.

Other models start on the 'More Cars 1' page the icon for which is on the left of this page - there are more than a hundred cars illustrated - don't worry if yours isn't listed the device fits almost all conventional petrol engines - if you want to be sure then email us. Also read the Frequently Asked Questions (FAQ's) page for more information - click here to go straight there.

(If you have no conventional inlet manifold access you will need to tap a manifold core or blanking plug or the manifold itself with a 1/4" BSPT thread).
 

The servo hose is most normally found by locating the brake servo drum and then the hose that leads either to the carburettor or (in the case of petrol injection) directly to the manifold (or Plenum Chamber) - as shown above on the annotated diagram or by this Golf GTi Turbo. 

Alternatively, any hose that draws a vacuum from the centre of the inlet manifold will also be suitable provided it is large enough (internal diameter of more than 4mm), such as a crankcase breather (PCV), indeed this should be checked first as a preferred option.  

 

Check hose for cracks or leaks – clean or replace as necessary. Cut the hose (using a sharp blade) as close as practical to the manifold (no closer than 3 cm) and ideally no more than 30 cm away but always inside (engine side of) any non-return valve (if fitted). Some cars are fitted with narrow gauge servo hose - this needs to be sleeved over with 10 mm fuel/emission hose and four 14 mm jubilee clips (a 2 inch length on each side of the 'T' piece will then slide over the severed servo hose).

For standard hose such as this Audi A4 1.8 5V insert each end of the CB-26P nylon ‘T’ piece in each of the severed hose ends and secure with jubilee clips or equivalent. This effectively rejoins the hose with the CB-26P in place - an airtight fit is essential and jubilee type clips are strongly recommended.

The device is now ready for tuning.  

 

 Tuning.
 

There are downloadable Videos of how to tune the device here: 

1. Windows - Broadband. 2. Windows - Modem.
3. Real Player - Broadband. 4. Real Player - Modem 

Players can also be downloaded by clicking on the media logos above -

A DVD and VHS Video is available showing the full fitting and tuning process on three separate car types, the DVD also has multilingual subtitles in English, French, German and Spanish - both are priced at £4.25 plus VAT (£4.99 incl.). They are available by phoning 0870 - 042 9574 - just ask for either the Ecotek DVD or Video Cassette.

Screw the locking ring towards the nylon ‘T’ piece as far as it will go.

Screw the cap containing the filter in the same direction (ie: clockwise looking at the filter) as far as it will go WITHOUT TIGHTENING. 

The unit is now locked off and you are ready to start the engine. This BMW 320i is easy to fit, with the servo hose fitting directly into the centre of the plenum chamber.

Start engine and allow it to reach operating temperature and tick over revs without choke.

At operating temperature gently unscrew (turn anti-clockwise) the CB-26P filter housing until you feel the unit vibrate, this should be accompanied by a LOUD induction noise. Close the unit (turn clockwise) until this noise stops.

Repeat step 4 until you are certain you have reached the point that the unit starts to operate (where the noise stops/starts) and then turn the filter housing clockwise through 90° (i.e.: by closing the filter housing one quarter turn from the point the rasping noise stops) and then lock it off at this point . With two units (for larger engines over 2.6Litres) tune each unit separately starting with the one furthest from the manifold.

On some modern engines, 2004/2005 onwards, the engines electronics can be so sensitive that the ECU warning light on the dashboard may illuminate after the Ecotek is fitted. If this is the case, simply re-tune the Ecotek adding 1/2 turn clockwise from the point the rasping noise stops rather than the normal 1/4 turn. After a few miles the warning light will go out . Adding the extra 1/4 turn to the tuning process simply lets the Ecotek to start to operate at slightly higher revs when the electronics are less sensitive to the small amount of additional air entering the inlet manifold to improve the combustion process.

Essentially therefore, tuning the CB-26P involves the following 3 steps (if in doubt watch the videos above):

1. Close the valve (turn fully clockwise), warm up the engine and, with the engine at tick-over, unscrew the filter housing until the device makes a loud and harsh rasping noise and close it to just the point the noise stops.

2. Be sure you are precisely at the point that the noise stops and then close the unit (clockwise) a quarter turn (90°) from that point and lock it there.

3. To lock the unit bring up the locking ring (anti-clockwise looking at the filter) to lock the filter housing at the point reached at the end of the step 2. (ie: 90° closed from the point the CB-26P starts to operate) and tighten the locking ring.

We wish you safe and happy motoring.
