"Welcome to the new age of tuning computerised vehicles. Over the years the coming of the computer did marvels for the automotive industry. Unfortunately workshops lost all control over the tuning of these vehicles. Even the slightest idling problem cannot be cured by the non-franchised workshop. In most cases even the authorised agents cannot cure these problems. In short, the tuning of computerised vehicles became nearly impossible.

The UNICHIP gives the properly trained technician full control over the timing and mixture functions of most electronically controlled vehicles. Not only can mixtures and timing be set, but also it can be set under various load and RPM conditions. This gives one the ability to optimise the vehicle for economy under light load conditions and set it up for optimum performance under full-throttle conditions.

The UNICHIP is much more than just a "chip". In actual fact it is a fully functioning computer which is added to the vehicle's existing engine control unit (ECU). Apart from controlling general timing and mixtures it can do idling control, drive extra injectors, take full control over timing functions, eliminate road speed governors etc. It can be accurately described as a "Piggyback" computer.

The UNICHIP gets wired into the existing ECU harness. If it is removed the vehicle is back to standard. Unlike other after-market units if the UNICHIP is programmed with zeros the vehicle will be standard. Only areas where the vehicle isn't perfect need to be altered.

The main difference between other after-market "chips" and the UNICHIP is that with the UNICHIP every individual vehicle is optimised. It is not just a chip that was made on one particular vehicle and then gets used on other similar vehicles"

I found this on Vortex. NiceTTs, is this what you were talking about?<ul><li><a href="http://www.dastek.co.za/">http://www.dastek.co.za/</a</li></ul>

i wish they put some pic of their chip and the controlling units..

"On most electronically controlled cars the timing and fuelling can be set at thirteen different throttle positions in 400 RPM steps. It is basically an extra computer which gets added to the vehicle. If the Unichip is programmed with zeros the car is standard. At any given RPM and Load points the timing is made faster or slower, the fuel richer or leaner until the desired tuning for that point is achieved. It is not needed to do all the available points (over 300) the Unichip will automatically fill in logical values between tuned points.

The Unichip is by far the most advanced piggyback system in the world.

It basically alters crank and load signals. The latest level can do boost control, water injection, nitrious injection with extra maps which are activated only once the water or nitrious becomes active. It can cut the nitrious at specified Rpm point as well as map the amount of water or nitrious versus RPM. It records the maximum RPM and boost for engine guarantee purposes and many other things. It can do launch control, drive extra injectors, accel enrichment, drive manifold flaps or cam solenoids and has many other functions.

We have three basic units. The one is for cars with distributors or few teeth on the crank signal. (Toyota, Nissan, some VW, some American cars, Subaru etc.) The next version is for cars with 60 minus two crank sensors (Typical Motronic like used on Porsche, BMW, Ferrari, Hyundai, Daewoo, Opel, newer VW etc.) The third version is for cars with 36 minus one or 36 minus two sensors, (Very latest level Toyota and Fords). We can do most of the cars on the market we know of but continuously develop the system to accommodate new cars. Any of the units can be set up in software to handle MAP, VAF, MAF, frequency based MAP or frequency based MAF sensors. We have manuals with detailed drawings for most of the cars as well as a detailed manual with instructions.

TT has 15 load points & non-uniform rpm points.

Jason Chen

and that means?

PanTTher

That means it's not as easy as Unichip makes it out to be.

It has to be easy.... they said so

expensive though. About $1200 with keypad.
