New Injector test equipment Stardex 0602cross graphic

Posted on 8th October 2017

We have just invested in the Stardex 0602 which is a highly professional universal device for testing Common Rail diesel injectors of different models and manufacturers.
Stardex 0602 is reliable and easy to use. The injector test procedure is fully automated checking all aspects of the injectors operations. 
Stardex 0602 contains in its database more than 1600 test plans for automated testing of Bosch, Delphi, Denso, Siemens, and Caterpillar Common Rail injectors.
The device is equipped with an electronic flow meter that quickly and accurately measures delivery and back flow of injectors and automatically fills up summary table with the measurement results.
What we do is to install the injectors on Stardex 0602, choose manufacturer from the list, put in part number of injectors to be tested, and push only one button to start the test.
After the test is performed, the system provides a detailed report about tested injectors.

We can vary pump rotation speed, pulse width, pressure in the fuel rail and change measuring units of the flow meter. The operator can create and maintain his own test plans thus tailor making specifications to suit all applications.

Great piece of equipment, allowing us to be more accurrate and reliable with our test specifications.

Hartridge HK1400 - latest innovation for PD injectorscross graphic

Posted on 21st May 2016

We have just added to our array of specialised equipment the Hartridge HK1400 which has been designed to bridge the gap between OEM approved EUI (electronic unit injectors) and EUP (electronic unit pumps) repair workshops and the general diesel EUI/EUP repair market.

It is a testing solution for all makes of EUI and EUP applications on the market including Siemens Piezo PD (Pumpe duse) injectors. Engineered by Hartridge for its functionality, accuracy and robustness allowing for no compromise on accuracy and repeatability of test results.

As we specialise in the testing, repair and up-grading of PD injectors fitted to the VAG group of diesel engines we are confident that by using the Hartridge HK1400 for the testing process we will be able to offer a superior service and product. The Hartridge HK1400 allows for the accurate and dependable identification of a faulty unit but also ensures that a repaired unit can be calibrated to OE (original equipment) tolerances.

The key test functionality is,

  • Response time measurement.
  • Electrical resistance.
  • Fully configurable pulse widths.
  • Injected quantity and shot count.
  • Automatic test limits generator.
  • Printable test result and analysis

The Hartridge HK1400 has given us the ability to check the following,

Failure to clean or replace blocked DPF's (diesel particulate filters) can result in poor engine performance, increased fuel consumption and finally engage engine management warnings - leading to expensive repair bills.

We have just invested in a revolutionary machine specifficaly designed to clean all types of DPF filters. Our DPF cleaning service in Shrewsbury uses state of the art technology to provide a fast and cost effective solution. Our regeneration process achieves 98% of the original new condition with certified results.

As well as generating significant savings for you, it removes the need to undertake costly on-going repair bills or having to buy expensive new filters.

Our technology is different from any other on the market because it allows us to clean all kinds of Particulate Filters and Selective Catalytic Reduction units (SCR) used in cars (Euro 6 included), buses, trucks, plant and agricultural equipment.

We don’t cut the filter, bake and weld it. We don’t dip it into a ultrasonic cleaning tank and then oven bake it to dry. United Diesel employs the Flash Cleaning Machine with its Organic Absorbent Emulsifier, flushing the filter both ways and then air drying it.

We are able to monitor back-pressure (mbar) and air flow (m3/h) before, during and after the cleaning process. A printed report then shows a comparison of the initial and final parameters in order to verify the quality of the cleaning.

Exciting and challenging times ahead with diesel emmissions being a hot topic in the news, we belive that with or DPF cleaner and our experiance in diesel emission reduction we will be able offer our customers a solution.

Caution when dealing with APEX Enginescross graphic

Posted on 8th July 2015

We searched for a reconditioned VW AXE and found various options, APEX Engines, at seemed to be the best buy, having spoken to Nick who went though the engine build we were convinced that the engine would be of good quality. APEX Engines sounded and looked like a reputable company so we parted with our money, bank transfer, no credit card payments acceptable? Did the transfer and was promised delivery 2 days later. I don't want to bore you but I never received the engine and after many excuses about the freight company and then finally it being dropped I asked for a refund. Have you heard the saying "drawing blood out of a stone" I think that that would be easier than trying to get my money back from Nick. Great guy, always returns my calls but lies so much that he even convinces himself.  A month later and still no refund. Companies like this need to be exposed inorder to protect others.

Viezu wins Queen’s Award for Enterprisecross graphic

Posted on 21st April 2014


Vehicle tuning specialist Viezu Technologies has won a prestigious Queen’s Award for Enterprise, the highest accolade rewarding excellence in UK business, in recognition of the outstanding innovation it has shown with its fuel-saving and emissions-cutting software, BlueOptimize, which has saved more than 200,000 tons of carbon emissions since its creation in 2011.

Developed in-house by Viezu over two years, BlueOptimize is the only vehicle tuning product focused solely on reducing fuel consumption and emissions. Viezu’s research and development has produced independently verified data showing that BlueOptimize can cut fuel use by 15 per cent and emissions by 20 per cent.

Commenting on the Queen’s Award win, Viezu Technologies CEO Paul Busby says: “This accolade is a huge endorsement of what our team has achieved. Through exhaustive research, development and a focus on quality, BlueOptimize has become firmly established as the only choice for fleet and private users looking to reduce the financial and environmental impact of their motoring.”

The cost saving and environmental benefits of BlueOptimize have attracted major fleet users including BT, which chose Viezu to remap its entire fleet of 24,000 light commercial vehicles. Thanks to the improved fuel efficiency of its vans BT is now saving £4million a year in diesel costs and estimates that the reduction in its carbon footprint is equivalent to taking 5,000 London cabs off the road.

The efficiencies delivered by BlueOptimize are achieved by making changes to the electronic programs and settings controlling a vehicle’s engine and power. These can include limiting maximum engine and vehicle speed, restricting full throttle ability and capping peak torque.

ISO9001 registered Viezu has invested heavily in its own internal R&D facilities in order to develop first-class tuning products. At its Euro 5 certified Worcestershire technical centre it has a government approved, seven-gas-analysing emissions tester and an OEM-standard 3000bhp, four-wheel drive rolling road with smog testing capability and drive cycle programme. Viezu also commissioned and specified development of a bespoke fuel metering system for BlueOptimize, which monitors and provides accurate, real-world measurement of fuel use in any driving situation.

“The Queen’s Award has now also recognised BlueOptimize as a genuine innovation, which offers what we believe is a unique approach to efficient vehicle tuning that’s very different from the traditional image of performance-oriented remaps,” adds Busby.

BlueOptimize economy tuning services today account for 95 per cent of all Viezu’s tuning activity. Viezu is the largest provider of tuning software in Europe and has 500 dealers in 45 countries, as well as 65 dedicated UK fleet installation sites. Its products have been installed on more than 120,000 vehicles worldwide, saving in excess of 200,000 tons of carbon emissions.

DSG (Direct shift gearbox) GEARBOX PERFORMANCE TUNING for VAG vehiclescross graphic

Posted on 2nd March 2014

We are now able to offer DGS Gearbox tuning for most VAG vehicles, VW, Audi and Skoda.  This means the ability to tune auto and semi auto vehicles with Sports Mode and some with Paddle Shifters or as some know it "Flappy Paddle" gear changing.

By tuning the gearbox we are able to achieve the following,

More responsive gear change and improved driveability

Removal of the soft, lazy gear change characteristics from daily driving

Improved safety – The reduced shift time means you spend less time waiting for the next gear during overtaking manoeuvres

Greater and more noticeable difference between normal DRIVE and the SPORT setting. The Sport setting can be made more responsive and even aggressive if you require. This creates a completely new gearbox dynamic for the SPORT setting which truly unlocks the additional power from the engine.

A TIPTRONIC that behaves even more like a manual gearbox. Adjustments to max rpm shift points for the track day enthusiasts. Additional power from the engine through torque manipulation in the DSG.

Torque increased from 350nm to over 550nm depending upon which level of tune required.

Up to 70% reduction in shift time in SPORT and TIPTRONIC modes, with up to 40% reduction in shift time in normal DRIVE

Fully unlock the power of an engine remap through the optimisation of the torque characteristics and thresholds within the DSG.

Viezu motors ahead in quality performance

Viezu has always been a market leader when it comes to offering motorists performance enhancements and total peace of mind and now this is official!

That’s because it has just helped to further raise the bar for industry standards by becoming fully ISO 9001 certified, not just for its products either, but the supply of ECU enhancement services including training and program development.

The announcement is a welcome boost for motorists looking for improved performance, lower fuel bills or a combination of the two, especially with the recent record fuel prices. The news also provides yet another cast iron stamp of approval for Viezu customers.

Paul Busby, CEO, Viezu, said: “To be one of the first aftermarket car engine tuning companies to achieve full ISO 9001 is great news for drivers of all cars but in particular those needing better performance, whether it be more power or improved fuel consumption.

“Of course, all our products and services are already fully insured and come with a full money back guarantee and this ISO certification gives another level of approval and reassurance.

“We are also hopeful that more and more professional tuning businesses follow our lead, so that anyone getting their car tuned knows that they will be in safe hands wherever they get it done.

Indeed, to achieve the internationally recognised standard is no mean feat as the Bromsgrove-based business had its entire operational business and structure put under the microscope.

However, one of the major bonuses now the Quality Management System is fully integrated is that Viezu’s 340 approved dealers can guarantee that the electronic files they use are ISO compliant, as well as obviously benefitting from the service back-up and product support from award-winning Viezu itself.

Paul added: “Our ISO status is also great timing because we’re seeing an unprecedented demand for our products, which we believe is partly due to more motorists wanting better fuel economy now that they are faced with petrol and diesel prices going through the roof. In some instances our products give drivers a massive 15 per cent improvement in fuel economy, no matter what vehicle or driving style.”

Indeed, an example of Viezu’s tuning expertise include a Vauxhall Astra 1.9 CDTi (’05 registration with 120,000 miles) which recently had its power increased by 20% to 180bhp and at the same time a 20% improvement in its fuel economy.

I'm also sure our approved dealers, who have to go through a tough approval process in order to wear the Viezu badge, will benefit greatly from our ISO status and make customers feel they are receiving the very best service available,” said Paul.

In fact, Viezu, which has developed more than 15,000 individual ECU programmes, recently doubled the size of its technical team and appointed a general manager as a result of the high demand for its services.

Paul concluded: “Viezu has been working hard to position itself as a centre of excellence in ECU recalibration and customers can rest assured that even though we’ve achieved ISO certification that we won’t sit on our laurels and will continue to look at ways to improve.
