Frequently Asked Questions



Our technicians link to the vehicles ECU or ‘brain’ with a laptop PC through the vehicles diagnostic socket and read the current engine management file which is then sent to our files office and custom optimised for you vehicle. The technician programs optimised file into your vehicle and you then have opportunity for yourself to experience the amazing results. On some vehicles it is not possible to carry-out this function by the diagnostic socket so in this case the ECU is removed and either a chip change or boot loading function is carried out, direct into the ECU. The final effect is exactly the same, only the process is different. Depending on the vehicle, the chip tuning normally takes less than 1 hour to complete the re-map.

Our StageX M re-mapping process enhances and optimises the power of the engine within safe limits, not beyond them. Extra power will also result in fewer gear changes. Manufacturers have to build in a tolerance for the parts in the engine, to manage the effect of wear and tear, production variations, and to ensure their warranty claims during their warranty period normally 3 years, are kept to a minimum.

Most race and rally engines are pushed for every last bhp, and thus they more common to fail, whilst normal car/van/lorry engines are limited back, well away from probability of multiple failures. Each individual engine is different as in how much it can be pushed in a remap, but a good ecu remap from a quality ecu tuner will never get close the limits of component failure.

You will see that the top companies within the market place have all develop vehicle improvements to similar outputs. Beware of tuners who claim significantly more, it’s either lies hoping that the average customer wouldn’t be able to tell the difference, or the engine is being pushed too hard and will quickly become unreliable.

Manufacturers generally sell one vehicle that covers various markets, with different tax and emissions regulations; different climates with extremes of heat, cold, humidity; different fuel quantities; different operating altitudes, etc. A manufacturer has to take all of these factors into consideration and make substantial compromises in the vehicles operation.

Sales and marketing also have a big affect on the way an engine is mapped. If you look the in manufacturer brochure at the engine specs, the torque graph will rise, then flatten out on a straight line, and then drop off. This obviously isn’t how an engine breathes, and it’s the request of sales and marketing to produce this flat lining of the torque. Why? Well it’s about having better torque figures than the competition and about local market taxation laws.

A professionally tuned engine will not cause technical faults with a well serviced and maintained the engine. In the extremely unlikely event of a problem we will 100% stand by the quality of our product, should any fault be assessed to have been caused by the upgrade.

If you want to tune your diesel vehicle and still keep the vehicles safety and durability functions for the engine/transmission/ESP intact, the only way to tune a diesel vehicle is to make changes in the existing control system of the engine.
That is exactly what we offer with a StageX remap. Our tuning process has total control over all parameters at any moment, and we don’t disturb the safety functions of the car, by deceiving the system.
Apart from an obvious power, torque and fuel economy benefits you get the following advantages with a StageX remap:

✅ The StageX Remap is installed within the hour, normally without lifting the bonnet
✅ Nothing needs to be connected to the vehicle after tuning to get the benefits
✅ No loose boxes and wiring flexes in the engine compartment
✅ Torque comes soft and smooth
✅ Torque is adjusted/limited on lower gears (to avoid damage on the transmission)
✅ Boost pressure and air flow is optimised
✅ The original settings can be reinstalled if required
✅ On board computer shows correct fuel consumption
✅ Anti skid program (ESP) function is fully retained
✅ Torque reduction when shifting gear (for comfort and durability) is retained
✅ Regeneration (emptying) of diesel particle filter (DPF) is retained optimal
✅ Correct calculation of exhaust temperature
✅ Correct calculation of service interval
✅ The diagnostic system is retained
✅ No enlarged NOx, HC, CO, CO2, Soot emissions compared with original when going for MOT and servicing

We are very confident that your StageX ReMap will both improve your driving experience and save you substantially on fuel. But, don’t take our word for it, try the upgrade for 30 days and if you are not delighted with the results we will take it off and give you a full refund.

We advise that it is your responsibility to inform your insurance Company of any modification to your vehicle. We are finding that more and more insurance companies are not penalising their customers for saving fuel and recognise our economy upgrades. We can provide a certificate of conformity if required.

Yes, in secure archival storage, should you ever require your vehicle to put back to original.

Some manufactures diagnostic equipment may detect a remap. Additionally many forward thinking manufacturers turn a blind eye to a quality remapping service , knowing that a properly enhanced vehicle can only ever benefit them. The official line from most manufacturers is that if a modification causes a problem with the vehicle, then the part of the vehicle affected will not be covered under warranty, this does not mean a unilateral cancelling of the whole warranty.

A full StageX engine remap alters the fuel, boost and torque characteristics of the engine. By controlling the fuel pressure, injected fuel quantity, maximum permissible visible smoke limit, boost pressure from the turbocharger and the torque characteristic.

A StageX remap offers a fully controllable change to the engine characteristics, whilst still operating with full engine feedback control and within all the preset engine sensor limits.
