FAQ's

Perhaps you are too far away from us, you are outside the UK or just want a more affordable service. Maybe you are a tuner who only has access to basic tools but needs to program a more difficult ECU.

Yes we have specialist knowledge that allows to remap the ECU by soldering, flashing or BDM.

No. The engine cannot work without the ECU.

We usually remap the ECU the same day we receive it and put it back in the post.

The most important thing to remember is that it is the QUALITY of the remap software loaded into the ECU that matters. We produce some of the highest quality software available that will give excellent performance and economy benefits whilst having the engine operate within tolerance.

We get asked this quite often, the reason is that they like to sell you the SRi, GTi or XSi model. This is usually the same engine with a different map on the ECU.

Another example of this is when cars have a “SPORT BUTTON” or “ECO BUTTON” this is either a switch able ECU map or the car has two ECUS’. Also with the pressure put on manufacturer to produce cars with lower exhaust emissions not higher MPG but lower emissions because of this cars, vans and trucks are not running to their best ability. Also because for example on a “VW GOLF” it is sent from factory with a ECU file that is detuned as theses cars are sent all over the world having to cope with counties at -25 to countries at +45. The quality of fuel can also vary enormously in different parts of the world. This is why when we REMAP your ECU we fine tune the parameters on the ECU to unleash your cars, vans or trucks true potential in less than 3 hours.

Not necessarily, we offer postal ECU services. The most important thing to remember is that it is the QUALITY of the remap software loaded into the ECU that matters. We produce some of the highest quality software available that will give excellent performance and economy benefits whilst having the engine operate within tolerance.

Yes we can make remap software to suit exhausts, air filters, etc. In some cases this Custom Tuning might cost more because of its complexity.

You can pay by credit/debit card over the phone or bank transfer.

A lot of our customers choose to pay for our remaps on finance, this basically spreads the cost of the remap over 4 equal payments over 4 months. We guarantee every customer is eligible for the finance.

Yes, please ensure your vehicle arrived with min of ½ tank of fuel and ensure your vehicle is mechanically sound.

No, in fact having a DPF will cause more problems than removing it altogether. Once the DPF is removed there is no need to worry about regeneration, power loss or expensive bills from the dealers.

A blocked DPF will use more fuel than usual as it is making the engine work a lot harder, removing the DPF will help the exhaust gases flow freely which in most cases will see an increase in MPG.

In the UK it is illegal to remove any of the original emissions equipment fitted to a vehicle from the factory. Vehicles with the DPF removed and detected will fail an MOT.

It is the customers responsibility to ensure they comply with rules and laws relating to their home country. Custom Tuning accepts no responsibility for the use of this part on the public highway where removal of emission controls is prohibited.
