ECU Remap Software

Yes it certainly can. An automatic gearbox in most instances is actually stronger than a manual so with regards to the power it is more than up to handling it. There are however a few things to note with regard to automatic gearboxes. If you have a DSG gearbox then we are able to modify the software to allow more torque and higher RPMS. If you have an automatic box which isn’t DSG then we are unable to remove the engine RPM limiters so although you get more power, the gearbox will still change at the factory RPM limiter.

The power of an engine doesn’t determine its longevity, the way in which it is driven and maintained does. Most engines these days are modular and therefore one engine can provide various power outputs from factory varied only by the software in the ECU. The use of modular engines highlights very clearly the large tolerances available within modern engines

The software itself is 100% reversible in terms of engine drivability and performance. With modern management systems being more complex there can be trace markers left inside the ECU which the dealer may still be able to see. In respect of selling a vehicle or simply returning to stock, we can ensure the engine operates at 100% factory specification.

Can my dealer find the remap?

As mentioned in ‘How will the remap affect my warranty’, no one can guarantee that your main dealer will not detect the performance upgrade on your vehicle. There are a multitude of ways a dealer can detect the remap;

· Internal DTC’s which only the main dealer can see.
· Changes to the ECU flash counter.
· By logging the engine parameters to check fuelling and boost levels against factory specification.

This is not solely for engine remaps, dealers have the ability to see if you have had or have a tuning box attached to your engine also.

In saying this, not all manufactures have this level of ability on their diagnostics so it is not definitive that they will discover it, in reality they very rarely do. We simply advise you that there is every possibility they may regardless of what any other tuning company may tell you.

Where we can source tamper proof bolt replacements we can replace any tamper proof bolts with genuine OE ones so that the ecu cage looks to be untouched.

For those where we can not source genuine OE bolts then we will try to utilise compatible bolts and those where this is not possible will leave visible entry marks. Contact us for more information on your specific model.

In many circumstances an auto gearbox is actually stronger than the manual variation. However, all of our software is designed to be safe and reliable for all systems. Should there be known limitations of a gearbox, then our software will have been designed to restrict peak torque values.

The gearbox controllers are based on torque load and thus will provide you with reduced lag on pickup but will not totally eradicate it due to the communication delay between the ecu and gear box controller. Our software is designed to work along side your gearbox controller to ensure smooth running of your vehicle.

Modern dealer diagnostics have been improved to detect for tuning whether it be a remap or a tuning box. Despite what any company may say to you, there is always a chance that the dealer can detect if it has been tuned. Where not all manufacturers look for this or have the ability we advise that there is always a chance of detection and all tuning carried out on your vehicle is at your discretion.
