    RPM Tachometer with Shift Light (Android & iPhone)

    Just digging in myriads of applications for Android, available via Google Play, I looked for something for my car to improve my skill of drive – tachometer (rpm gauge) with shift light. My car has performance chip tuning installed (btw this is Audi A6 Allroad with diesel engine) and I rev it a lot, as this is fun for me. Name me a big child but I love to launch at green light like rocket (sometimes I'm even faster than Ronnie o'Sullivan, LOL).

    Installing shift light with big additional RPM tachometer needs a lot of wiring and it is even more complicated in diesels. In gasoline engines pickup of tacho signal is possible from coil, or injector. In diesels (especially modern diesels like VW TDI or Audi TDI, or even Porsche Cayenne diesel) injectors are driven by high voltage and/or have multiple open/close phases throughout combustion cycle.

    A solution may be acoustic tachometer (rpm meter gauge) with shift light I found at Google Play - c. It works as they describe with Z-transform of sound, your cellphone hear from engine. Even noise of air conditioning or moderately loud radio music is not a problem. Screen blinks yellow when revs are too high. Beside that I have nice tachometer gauge at phone screen. Maybe not extremely useful when I have my own tachometer in the car, but shift light is worth that dollar.

    That RPM Tachometer with Shift Light is a part of much bigger project from CIRI ( and their idea is to make full diagnosis of engine only via listening its sound and sophisticated sound processing. It will also detect knocking – that's worth a million for tuned cars, especially with performance chip tuning installed.

    App will be available for iPhone users too (I personally use Android HTC 3D phone and it works for me).

    CIRI - Car Intelligent Recorder & Interpreter - New Method of Car Engine Diagnosis.
    Do you wonder if there is any method of scanning car's engine for malfunctions without investing in expensive expertise and/or OBD scanners?

    C.I.R.I. helps you to record and analyze the sound of your enginefor malfunctions, strange noises & defective behaviour. It works likecar diagnosis, but basing on sound of engine. It listens to your engine's sound and with sophisticated analysis methods it searches for a wide range of mechanical and combustion problems. You can also store a "fingerprint" of your engine for future comparisons if you suspect that the engine's sound is altered.

    How does C.I.R.I work

    C.I.R.I stores a fingerprint of your car’s engine sound using your phone or pad microphone including all noises, including sounds, that people cannot hear. Stored sound is processed via sophisticated analysis, sound transforming and factoring and finally compared with other engines stored sounds. This can give an answer you expect: 
    Is everything OK with my car?

    C.I.R.I Advanced Cloud Server

    In C.I.R.I. Advanced version it is not only your phone involved in analysis and expert check of your engine - you can extend accuracy by sending your fingerprint anonymously to C.I.R.I. Advanced cloud servers, where it will be compared with whole database of malfunctions’ sounds. Powerful servers that work for your C.I.R.I. can process sound of your engine using dedicated DSP processors and thus - improve recognition accuracy. You can also re-check your engine by comparing it’s actual sound to any historical fingerprint sound stored in C.I.R.I Advanced Cloud - with any device, phone or tablet.

    C.I.R.I. Advanced is sophisticated car diagnosis system - it may listen to your engine non-stop and will allert you while detecting knocking or other strange behaviour you may not hear.

    Car Tuning in Vancouver – Performance Chip for Mercedes, Audi, BMW and Ford Cars
    Maybe you have heard about performance chip tuning (also referred to as "chipping", “ecu tuning”, “car tunning” or “ecu

    remapping”). This name is commonly used for increasing power and

    torque in modern cars - especially popular in Volkswagen. A performance chip

    is a program alteration that changes the engine parameters. One particular type of "green" chipping is fuel efficiency tuning - when the car tuner focuses on

    increasing mileage and fuel economy. Performance chip popularity is growing in the Vancouver region and there are more than 10 garages and workshops that offer such chipping and fuel economy tuning upgrades. Is seems to be clever alternative for downsizing of engine and car to save fuel and money. Some will buy battery-powered or hybrids like Prius, but it is hard to imagine electric Porsche Cayenne or electric replacement to Audi R8 :)
    The highest differences in torque and power can be achieved in European cars- BMW, Audi, Volkswagen, Porsche.  Also popular are the Audi S4, Audi S5 and RS5 (and fabulous R8) with 4.2 FSI engine. Of course, the power gain will be clearly visible during dynamometer testing. Excellent results can be achieved with Audi 2.0 TFSI engine, also using external powebox called V-tech BlueBox (this option is perfect, when you want to switch power of your car with iPhone or Android phone). 
    It is critically important to measure

    the performance of the car with a dynamometer (if you don't know what chassis dynamometer is, see here gallery with chassis dyno with cars at dyno). Dynos provide the unique opportunity to see the real results of chipping - increases in power and torque.
    Many naturally aspirated cars, such as

    the Ford Mustang and Focus, have smaller gains but higher mileage

    after chipping. Upgrade, chipping and increasing fuel efficiency of Ford cars is still easy, but

    dyno testing is necessary in order to see the smaller changes.

    As dynamometers are quite expensive tools, they are rarely present in garages nowadays. You can read more about Audi, VW, BMW & Porsche chipping here.
    Professional chiptuning is available in Vancouver. But, only few of the best performance tuners offer

    dyno testing. One of them is Vancouver West Motors. Another famous one is Tunexperts in Port Coquitlam.

    Typical Sources of Problem While Set Up of Vehicle at the Dynamometer Part I
    Very common sources of problems while testing various cars with chassis dynamometer is to set up a car properly at the stand. Owner of rolling road should remember on proper positioning of driven wheels vs drums. Wrong or inaccurate positioning and alignment may cause not only tire wear or cuts in their surface, but even serious accident. I have had some such accidents in my long career.
    Let's analyze most popular mistakes:
    1. Driven axle is moved (positioned) to the front versus symmetry line of dynamometer rolls (if dynamometer has two drums like that one from photo below) or middle of the drum (in one drum dynamometer). In that case while accelerating, traction forces will move the car to the front of the dynamometer. Sure, you can use as many belts you want (or have ;) to keep the vehicle at the dyno. But all types of belts have their own elasticity and even oversized belts intended for heavy loads will be expanded a bit while being tensioned. In two drums per axle dynos we may observe climbing of wheel onto front drum, along with releasing traction force from rear one. Two problems may happen: first is that car will have higher power measured than real (if sensor of rotation is at front roll – this is usual with chassis dynamometer with eddy-current brake). If sensor is located at the rear drum, measured power may be lower than real. This is result of tires loosing contact with drums, thus causing some inertia of drums not be considered in whole result or being added improperly (for instance added as losses fully, and as load – in part). 
    2. Moving vehicle axle to the front of symmetry point of dyno roll/rolls may cause more spectacular problems. In one drum per axle dyno, tire of the car may touch covers of dyno, causing burning or damaging tires but also jumping the car out of the dynamometer. In two drums per axle chassis dynamometer & leistungsprüfstand  such risk is minimized, but while releasing gear to neutral at top speed, car may burn tires because of friction against rear drum (imagine critical situation, when rear drum was not spinning at all because the car was able to “climb” enough onto front roll to cause fully loosing contact between tire and rear drum.). Then, while switching to neutral gear, car “simmers” into drums and lazy rotating rear roll is spinned now with force delivered by tire. friction will burn tire in seconds.
    What may happen when we set the car in opposition to the example above – next time.

    Fuel Saving Tips And Ecotuning (Ekotuning Performance Chip Tuning) - Tricks Of Money Saving On Fuel

    saving is a popular idea of drivers across whole

    Earth. Popularity of websites with tips

    on fuel saving rise and it is clearly to be increasingly

    important topic
    . Prices of petrol fuels like gasoline

    or diesel fuel are higher every year. This is result

    of various conflicts in countries, where oil

    is digged out, and information, that rest of crude oil still

    available is going to zero.


    have no special influence on the price of energy,

    especially price of fuels. It seems that there still are some

    ways you can save cash on fuel:

    1. Drive

      politely and change driving style to “eco-driving”

    2. Improve

      your car to burn less fuel (wide subject)

    3. Change

      vehicle to other, with smaller engine.


    1. Some useful tips on eco-driving are: close

    your windows on the highway

    (air drag at the high speed eats fuel), speed

    up moderately but not too sluggish, try avoid stopping

    when it is possible, roll towards queues and avoid joining them with

    hurry. Also car sharing may be good deal (of course if

    you have a neighbor to share your car while



    2. There are some products that improve fuel efficiency

    of engine and overall efficiency of the car. Special “green”

    tires reduce roll losses and can improve overall fuel economy by few

    percentage. Other tip is - using lowest possible octane

    number permitted to be used in particular engine (not because it is

    cheaper, but because it burns better and gives more energy,

    if engine is developed to be fed with it).

    Another trick may be eco-tuning (fuel saving performance chip

    tuning). Interesting material with test results can be found here


    - use

    Google translate to translate it from Polish language).


    3. Downsizing of engines is clearly best method of fuel consumption

    reduction. See VW Golf & Jetta TFSI & TSI –

    older models of Golf had 2.0 FSI engine installed,

    with raw 150 hp of power. Now newest models base on small

    turbocharged engines, 1.2 TSI Bluemotion (105 hp but with

    perfect torque) and 1.4 TSI (140 hp and again nice

    torque in wide range of engine revs).

    US Versions of European Cars – Performance Chip Tuning Issue
    I have noticed, that almost all owners of European cars across North Americe think, that their vehicles, even with “localized” names (like Mercedes Sprinter = Dodge Sprinter) have no technical differences to EU specs. They believe that they buy real EU vehicles, and the only additional equipage is local road homologation, or CD with navigation of USA & Canada instead of german"Fatherland”.

    Wrong! Most of these cars have huge differences, not visible at the first and even second look. They are hidden in ECU installed in the car and involved in total control of engine, fueling, fuel burning quality & efficiency and finally – torque and power of the car.

    Due to differences in SAE normative for car power and torque measurements to more restrictive DIN German normative, producers of cars have nice gap of few % between power declared in EU (where DIN rulezzz ;) and USA & Canada. And this gap is good for them and bad for us. They can reduce power of the car by few % and still have same declared power, as presented in EU. Car may consume less fuel because of such changes, but this is typical between car brands to keep the torque and power of engine as low as it is possible, if only any chance is visible on the horizon. So they do that.

    I have measured many BMW 335i with 3.0 biturbo engine – US versions have ca. 15 hp lower power than same version in Germany (test was held by changing software for USDM to EUDM, not by replacing cars at the chassis dynamometer). Same situation occurs while dyno pulling Audi 2.0 TFSI or TSI and 3.0 TFSI cars. Same is in beloved Porsche Cayenne 4.5 turbo or GLS. Always lack of few percent hits our eyes at dynamometer graph. 

    I may believe that producers may try to adapt their products to US-market gasolines. But they differ only slightly (as norms differ slightly). What to do?

    Alternative for Porsche, BMW, Audi and Mercedes cars is performance chip optimimization. Increasing power of cars by specialists clears the power lack described above, and feeds engines with nice rancho of new power horses. Also mileage will be increased by clever changes of ignition angles vs level of boost and alterations in camshaft angles (where applicable variable camshaft control aka vtec or vanos).

    Audi, BMW, Mercedes or Porsche performance chip tuning specialist can do all that with your car, using European software editor, real DIN normalized rolling road imported from Europe, with all that knowledge base build by European tuners for their vehicles. If you buy car for huge thousands of dollars, it is rather good idea to tune it at real masters, even with their funny European English ;). BTW if you are a real tuner, you can buy Vtechdyno European chassis dynamometer just at Tunexperts in Canada or USA.

    How to Improve Results of Dynamometer Pull and Make Them More Repeatable?
    Measuring power with dynamometer may give results, that vary from bench to bench, but also even two in-line measurements may give different results – with difference of more than 5%. How to improve results and make them more repeatable? 
    It is very common mistake of tuners to use wheel horsepower instead of engine power (flywheel horsepower). Because flywheel (engine) horsepower is a sum of horsepower loss curve and wheel power curve, tuners believe in wheel horsepower as it has lower measurement error.
    They do not notice, that there is additional source of erroneous result – temperature of wheels, and inconstant friction of all mechanisms, that connect engine's flywheel and asphalt. This is "driveline" loss. You loose some power in the transmission (gear and oil friction). You also loose horsepower in the rear differential or in all differentials (when we consider 4x4 car). All these depend on temperature, including real ace of losses – friction between the tyre and roller on the dyno itself. They should be measured every time, not once per session at bench, or even simulated by coefficient (like WHP * 1.18 = HP).
    Professional dynamometer measures complete power loss every time, every pull. Not all dynos have such option (but most of them have). Vtechdyno rolling road dynamometers use precise loss measurement.
    Our division in Canada, Tunexperts says, that about three quarters of potential dynamometer customers (car tuners that do ecu remapping and optimization) ask for WHP and say, that they plan to use WHP as representation of their work results. In Europe engine power is the only result considered as real result.
    Remember – even changing tire pressure or tires changes WHP. But with professional dynamometer such loss will stay unaltered between pulls, after tires change.

    Three Main Reasons Why You Need A Peformance Chip
    Every time anyone of you thinks about better performance of his/her car first in mind is to change it for more powerfull one – not bad concept if your wallet can handle it in case when your job is very well-paid. But we all understand that we must pay for rent, our food, bills and other ‘goodies’ we need so last thing on what we can spend money is a new car. Do not give up your dreams so quickly and read more.

    According to the previous paragraph this is first of the main reasons why you need peformance chip more then new auto  – money. You can still have more powerfull car without buying new one. 

    Next reason why your car need it is improvement of engine power by add more horse power and change torque of the motor. Don’t forget - chiptuning VW Audi Seat Skoda or other models is a cheaper way then any other types of tuning.

    The last one will be ace up your sleeve - peformance chip can reduce combustion of the car what in global calculation is the most important advantage which speak in favor of chiptuning.

    Now you can imagine why performance chip is so helpful. Maybe you start thinking about beginning your own business in tuning world? It is not so hard check this chiptuning files & tools download section to read more about how to get started.

    My Birthday – I'm 37. :( Time To Think How To Have Longer Live. Anti-aging technology
    Please- do not laugh –

    I'm 37 today. Sitting quite happy and meanwhile sad at the fireplace

    with good whiskey on the rocks (thank you, my fabulous friends !).

    Loving cars & women I started to think – am I in the middle of

    my lifespan ? This seems common. It would be nice to be Caroll Shelby

    and keep that energy of life until being just old. I love his ideas.

    This time it will be not so

    rubber-smelling story. Wanna stories 'bout dynos? Go to my chassis dynos company. I seriously think what to do at 37. I'm quite

    successful and handsome guy. My company in 3 countries produces a lot

    of dynamometers. But money cannot stop my aging. At least I have

    found that my money can make my life longer :)

    Strange? Stupid? Not so. Maybe you have

    read a lot of stories and ideas about longevity of life. Multiple

    supplements-shops offer hundreds of miracle-pills. But which one is

    really proper one? In famous Matrix firm Neo had to choose from two,

    different colored. Try to be them, choosing from thousands of pills,

    most of them not really working. Selling miracles is common method of

    making business. How to prove if they're true promise of longer life

    ? You will see, you will see.

    Ok, I have decided to use crazy

    scientists' ideas. LongerLive – answers to the question how to live

    without asking you to eat buckets of carrots. They use razor

    edge knowledge about hormonal and genetic aging and reverse it. With

    some simple tricks.

    Honestly I have been using their

    technology and strategies and tips for anti-aging for last 3 years. I

    believe they work for me.

    Wish me happy Birthday !

    Tuning Seat, Skoda, Audi, VW to specjalizacja?
    [Abstract for English Friends]: I write about companies, that prefer focusing on chiptuning of one brand or group of cars (like VW, Audi, Seat, Skoda). 

    W zakresie zwiększania mocy silnikównajczęściej zadawanym ostatnio pytaniem wydaje się być to, czy specjalizacja firmy tuningującej auta konkretnej marki czy grupie samochodów daje przewagę nad warsztatami, które realizują dowolne zlecenia klientów.

    Ciężko ocenić, czy strategia specjalizacji w tuningu elektronicznymjest skuteczna. Z jednej strony mnogośćtypów pojazdówsugeruje, że warto tuningowaćsamochody w sposób specjalizowany, jednak w w większości pojazdów sterowniki silnika są takie samew zakresie zbliżonych roczników. Wynika to z faktu, że producenci samochodów instalujątakiesterowniki, jakie zdołają kupićod poddostawców. Podobnie rzecz się ma z częściamitakimi jak turbosprężarki. Niekiedy różnica dotyczy gniazda czy innego uformowania mocowań.

    Jestem zwolennikiem uniwersalności firm tuningowych. Chiptuning Audi, VW, Seat, Skoda - pojazdów jednej firmy to najpopularniejsza oferta ale dobry chiptuner poradzi sobie również z innymi markami.
