1. What do you do exactly?
We link to the vehicles ECU or ‘brain’ with our unique remapping equipment through the vehicles diagnostic socket and read the current engine management file which is custom optimized for your vehicle. The technician programs the new ECU Remap2Race optimized file into your vehicle and you then have the opportunity for yourself to experience the amazing results.
On some vehicles, it is not possible to carry out this function be the diagnostic socket so in this case the ECU is removed and either a chip change or boot loading function is carried out, directly into the ECU. The final effect is exactly the same, only the process is different. Depending on the vehicle, the remap normally takes less than 1 hour to complete the re-map.
2. Is it safe for the vehicle?
Our Remap2Race remapping process enhances and optimizes the power of the engine within safe limits, not beyond them. The 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 the more common to fail, whilst normal car/van/lorry engines are limited back, well away from the probability of multiple failures. Each individual engine is different as in how much it can be pushed in a remap, but a good remap from a quality tuner will never get close the limits of component failures.
You will see that the top companies in the marketplace 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.
3. Why don’t the manufacturers do it?
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 vehicle’s operation.Sales and marketing also have a big effect 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 for 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.
4. What warranty do you give?
5. Please explain what remapping is?
6. Do you offer a trial period?
7. Do you keep a copy of the original tuning file?
8. What about insurance?
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 penalizing their customers for saving fuel and recognize our economy upgrades. We can provide a certificate of conformity is required.
But ask yourself a question? Has the vehicle been remapped before? if it is a secondhand or used vehicle who knows? We have arrived on many occasions to find that the target vehicle has been remapped before and the customer not being aware. So how can you declare to your insurance company that the car has not been modified in any way?
9. Does it affect the manufacturer’s warranty?
This question does not have a straightforward answer. There are European Commission laws in place to stop anti-competitive practices in the motor vehicle sector. Our research indicates that It is deemed anti-competitive and therefore against the rules for manufacturers to invalidate a warranty because a vehicle has been worked on by an after-market supplier of parts or services.
We believe this should apply to ECU remapping and tuning services. If it is stated in your vehicle’s documentation that remapping your ECU will affect the warranty then it is possible that your warranty may not apply. However, firstly the warranty company would have to prove that your vehicle has been remapped and secondly they would have to prove that a remap was the cause of a failure. Unlike many remapping companies, we ONLY carry out sensible, tested remaps that stay within the mechanical limits of the vehicle’s components.
An ECU Remap2Race, remap has never been questioned in relation to mechanical or other failures. However, to give our customers peace of mind, we have fully underwritten product liability insurance warranty (optional cover), UK insurer so that in the (completely unheard of) event that failure was to occur and was not covered by standard manufacturers warranty, it would be covered by our own insurance.
Part of the European Block Exemption Ruling states that a manufacturer cannot cite after-market servicing or parts to void a warranty or reject a warranty claim. There needs to be proof that the work carried out is the direct cause of the failure. If this cannot be proved (and the burden of proof lies with the manufacturer) then the claim should be fulfilled. Although this section of the ruling is mainly aimed at servicing we believe, at the time of writing, that remapping/tuning comes under the same rule – i.e. it has to be proven to have caused a failure or the manufacturer must fulfil the warranty claim.
10. How does the remap improve the vehicle?
11. What do diesel add-on tuning boxes do?
We do not fit add-on tuning boxes, which normally just interfere with engine management signals to trick the injectors into adding more fuel. Our service is a custom remap of your ECU, specifically for your vehicle. These differ from how a remap works. A tuning box relies on the principal of more diesel fuel = more diesel power.
That theory is correct and boxes do increase power, but they can’t control the amount of black smoke (maximum permissible visible smoke limit) coming out the exhaust. Too much smoke is undesirable, both environmentally and visually. More importantly, the black smoke is unburnt diesel fuel attached to the combustion chamber, with deposits exiting straight out the exhaust pipe, thus wasting fuel which hasn’t had any effect on power gain.
The results are raised emissions, a higher thermal load on the engine (i.e. exhaust temperature) and frequently defects such as “bucking” are often the result. It should be clear what this means for your engine.
