Tunit.

Pro-Tech are authorised installers for the Tunit range of products.

Tunit provides an efficient and adaptable method of enhancing a vehicle's performance (power and torque) without the need to alter the vehicle's original equipment or programming. The advantages of the Tunit are:-

1. Adjustment for optimum efficiency (both manually, by the customer and electronically, via a PC by a distributor).

2. Flexibility, as in movement from one vehicle to the next.

3. Ease of installation.

Further to this recent advancements have not only further improved performance but also reduced harmful exhaust emissions by up to 27% while improving fuel economy (these statements have been backed up by independent research).

The principle of Tunit is to provide all these advantages that previous methods of tuning such as EPROM replacement and "flashing" or OBD tuning could not. The Tunit performance product carries an extensive three year warranty, 1 year Engine and Driveline warranty, part exchange program and extensive after sales service.

What is a Tunit?

The Tunit is an externally installed performance product suitable for all modern diesel engines. Tunit is designed to improve power, torque and efficiency, without compromising fuel economy. In most cases applications will achieve a 7-10% saving on fuel. It is retro-fit and will not interfere with original equipment or the manufacturers warranties. Installation is usually a swift process of less than 30 minutes. Thanks to Tunit, diesel tuning is possible to increase the performance of all modern diesel vehicles by up to 30%

You may appreciate your diesel vehicle for its fuel economy, but you find it a little lacking in power! Or maybe you just want that bit of extra get up and go. The Tunit has the solution! This innovative and clever device provides a substantial increase in power and torque for the amateur or serious performance user.

How it Works

All Tunits are specifically designed to achieve enhanced diesel performance by modifying the fuel injection parameters and only by the careful interplay of these values and characteristics can the optimum performance of your engine be achieved. The turbo boost pressure is not directly altered (on turbo models) by the Tunit and is only increased via the natural increase in exhaust gases provided by the increased performance. The design and development of the Tunit has come about by the collaboration of some of the top minds in Europe and is the latest and most advanced device available on the market today. Our ongoing development programme ensures we keep up to date with the latest engine management and injection systems.

Installation

Every Tunit is designed to be compact and lightweight, the smallest being only 10cm across, the largest being 13.5cm. In most instances the Tunit comes complete with original manufacturers plugs and connections. An original quality harness to fit in-line is also provided. Most Tunits are fitted in 10-20 minutes and all are designed to be easily installed by people of average mechanical capability. If you prefer, we fit the Tunit for you. Fitting is offered by our international network of world wide distributors. Fitting is usually carried out in less than 20 minutes Fitting at any of our distributors does include a try before you buy so as you can be assured of the performance before you purchase. If you wish to remove the Tunit for either fitting on another vehicle or for any other reason it is just as easy.

Adjustable Tuning

Manual Adjustment - All Tunits are adjustable in one form or another. This allows the Tunit to be individually matched to each and every characteristically different vehicle. This can be very important as two cars the same may not react and drive the same. i.e. one VW Golf 110 bhp may produce 105 bhp, the next Golf built on the same day may produce 115 bhp. For this reason we have built in simple methods of reaching your optimum performance.

The Tunit V-CR, V-PD and V-VP models come pre set for the vehicle.Each Tunit has a 9 position rotary switch. Each position will provide a different power level. 1 is the lowest, 9 is the highest. The Tunit II, III and IV also have a manual adjustment and require a simple adjustment on installation to the vehicle.

Laptop Tune

The V-CR,V-VP & V-PD Tunits also have adjustable tuning via a lap top. This is a form of tune uniquely introduced by our company. Lap top tuning does considerably more than the manual adjustment. Once the Tunit is installed you can actually sit in the drivers seat and the Tunit can be re-programmed, by a Tunit distributor, as you drive along. As well as an overall power increase, the power can be moved further down or up the range and the power delivery can be varied to be smooth or aggressive.

Another great advantage of this is that if you decide to enhance your vehicle further, through maybe induction kits, intercoolers etc. you can easily adjust the Tunit to match the new modification so the full potential can be reached. With fixed map devices and chips this is not possible and a new chip or device would be required.

*We recommend a lap top tune if you add other performance parts such as intercooler and induction kit or if you have specific requirements such as heavy towing or large loads.

What is Achieved?

Immediately the increased power and torque can be felt. The throttle response is improved and particularly low and mid range torque is vastly improved, making the overall performance of the vehicle completely different.

When carrying loads and/or towing, the extra power is a also great advantage. The overall drive becomes more pleasurable and the engine in most instances runs smoother.

In independent tests and trials, results of 7-10% extra better fuel economy have been achieved. This obviously varies from vehicle to vehicle and application.
