Choose the best diesel tuning system available!

Unlike cheaper, untested, "generic" systems, the CHIP Express™ digital tuning system retains all the protective functions and fault diagnostics of your vehicle's original ECU; always operating well within engine tolerances. Our digital microprocessor circuited units are all manufactured using the highest quality surface mounted components contained within a compact, light weight and robust housing. In addition only adaptor plugs that simply plug in to existing connectors are used. Every CHIP Express™ system undergoes rigorous and extensive testing on new vehicles ensuring safety, reliability and suitability requirements are met. Rest assured you are buying the best quality, most rigorously tested system available!


How the CHIP Express™ system works...

This is no "generic" system, no "one size fits all" solution - using digital microprocessor technology the CHIP Express™ system utilises proven engine-specific dynamic maps to analyse the individual data for different fuel injection cycles and conditions millions of times per second, the information resulting from this analysis is used to take advantage of the engines lean running to optimise combustion efficiency and improve atomisation by precisely re-calibrating the injection system. This intelligent feature gives the unit the ability to adapt to your own driving requirements, all without the need for any complicated "manual" adjustment or tweaking! That is what we mean when we say the system "works right out of the box".


Why buy CHIP Express™ over cheaper analogue or generic digital tuning systems?

Chip Express™ digital tuning systems are far superior to analogue units. There are many inferior analogue designs currently on the market; the first is a resistor in a box that either trips the ECUs cold fuel maps within the low RPM range only or fools the air flow meter readings. These crude methods of tuning have many associated problems. Next is a resistor type analogue or generic digital chip; these systems use primitive electronics and have no intelligence. They may initially work to a degree but often cause poor idle running, hesitation, smoke on acceleration, engine lights to illuminate, limp mode (as they are working outside safe parameters), DPF / FAP blockage or regeneration issues. These substandard methods are NOT engine specific and non-comparable. CHIP Express™ systems are different; they use unique and innovative software in conjunction with the very best components, giving you the next phase in digital tuning technology. Our solutions combine impeccable build quality with unique electronic design. What's more, they are bespoke to their application, fully digital and keep the engine standard at idle whilst providing optimum power throughout the rev-range. This engine specific, tested and approved software is held in the serial memory and works via a sophisticated timing circuit using high speed multi-microprocessor technology, optimising your engine power safely and providing a driving performance second to none. Why take chances? Choose the No. 1 provider of diesel performance enhancing solutions, buy only the very best for your vehicle from a company unequalled in innovation.


CHIP Express™ versus chipping or a remap... what is the difference?

Chipping involves the physical opening of your vehicles ECU (electronic control unit); often breaking tamper proof seals in the process (thus immediately invalidating your vehicle warranty), the standard chip is then de-soldered at great risk and replaced with a modified version. A remap like chipping also requires the removal of your vehicles original ECU settings, meaning that returning your vehicle back to standard can also be a major complication. The CHIP Express™ plug-in system addresses these issues as it works in conjunction with your original ECU settings rather than replacing them, it can easily be self installed, removed, adjusted for more performance and transferred if you change your vehicle - it cannot not be deleted during routine servicing, even if left fitted. Importantly it must be noted that the CHIP Express™ system works from part to full throttle load, enhancing real world drivability even on light throttle openings, other methods respond at close to full throttle load only. The CHIP Express™ system also produces more low RPM torque when compared to a remap so it’s ideal if you drive a laden vehicle or if you are looking for better economy potential.

What others are saying...

“Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.”

“I must say l'm delighted with the improvement from your chip, its on the standard settings and the difference in the car is amazing!!! I have a smile on my face every time I get in the car, and there is about 5-7mpg improvement. With the mileage l do, l can see myself getting my money back in no time at all. So if your a doubter like me, don't be because its one of the best things l've ever bought!!!”

“May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery. I have tried other diesel tuning boxes for my previous vehicles (Kia Sorento, Peugeot 206 and Vauxhall Vectra)... and they all produced slight engine stuttering under certain load conditions. The CHIP Express system does not show any evidence of this and is equal to the likes of an ECU remap (which I have also had done before) for smoothness and noticeable power gains. This would be the only diesel tuning product I would recommend.”

“A friend recommended one of your "gadgets" a year ago and being not-very-techno (but Scottish and keen to save money!) I bought one. The gizmo has TRANSFORMED the performance of my Land Rover Freelander 2 TD4 AND improved the fuel economy by a genuine 15%; so much so that I have bought another one for our Freelander 2 SD4 which is now a REAL Q-car! (And of course saves fuel...) I have never written a review before (though strangely I do read them and take notice of them, whilst half-believing that they are written by the owner's chums!) so to have made me pick up pen & paper so to speak - I MUST be delighted! Thanks for making technology so simple and so successful!”

“Be assured, this is NO gimmick. Arrived yesterday (less then 24 hours after the order was placed) and fitted today. The fitting was easy especially with the photos and instructions sent with the chip. The first thing I noticed was the responsiveness of the engine from a standing start, no more lag. I then went on a 30 minute drive both motorway and sideroads and my average fuel consumption went UP from 33.3mpg to 38.7mpg. My motorway speed varied from 60 to 85mph and the sideroads from zero to 40mph. I am so pleased with the whole result. This is worth every single penny paid. Thank you!”

“As do many, I took the 'if it sounds too good to be true, it probably is' approach to performance chips. But CHIP Express were recommended by an impeccable source who had had experience with their product on my model of car - a Citroën C6 with the 2.7 HDi twin turbo diesel. Following a first rate response to a query, the product has delivered in spades. Ten days and more than 1000 miles of mixed town, country, low and high speed driving later I am certainly getting more than 10% more from a gallon, and probably 15%, and the performance is markedly better. Low speed response is immediate and has eradicated what I took to be baked-in lag in a big automatic turbo diesel, and mid-range acceleration is silky smooth, including up inclines. A very good car has been turned into the excellent car I had hoped for all along.”
