Chip tuning, why don't the manufactures do this?

You may have wondered why a manufacturer can have the same engine in different models but they can have different power outputs.

This is not due to the engine mechanics, as they are usually built to the same standard, but it's down to the software installed in the ECU which governs the engine's output.

Manufacturers don't use diesel chip or common rail tuning modules because of strict emissions regulations, tax bands, altitude (effects oxygen levels), temperature, fuel quality etc. They build the lowest number of variants, which suit all worldwide markets. By doing this they compromise performance and economy.

How easy is it to fit?

Most installations can be done yourself within 15-30mins. No special tools, soldering or wire cutting is involved. At most you may need a screw driver to remove any screws holding the plastic engine cover on, but that's it. It's the ideal DIY project!

We provide a comprehensive installation guide taking you through the whole process.

Will it harm my engine?

No. Our diesel chip tuning unit sits behind all the engine's safety features which remain active. Control of the engine safety features are ALWAYS with the car's ECU. It is not actually possible to damage your engine if the product is installed correctly.

It is important that when applying performance tuning to any car that the engine and clutch should be well maintained and not suffering from age or neglect in any way.

High millage cars or areas with very poor fuel quality should avoid chip tuning.

So how does the unit work?

We have prepared a technical overview document to explain how the common-rail diesel engine works and the tuning process we use. Click HERE to view.

Will I really notice the difference?

Absolutely, you won't have to ask yourself "Is it working?"

Can I adjust the power setting?

Yes. the chip tuning unit is fully adjustable with 16 tuning programs. We also pre-set all units prior to shipping so in most cases it's plug and go.

How does this power increase improve fuel economy?

In addition to controlling the diesel fuel delivery, our chip tuning unit provides more torque through the engine, particularly in the low to mid range. This allows the driver to change up to higher gears more quickly and enables use of the higher gear for longer. MPG gains are delivered as a result of this control over the fuel system and the effects of more torque.

How can I pay for my diesel chip?

We accept payment via PayPal, this allows you to pay by any major credit/debit card without needing to sign up for an account (aka 'Checkout As A Guest') and allows us to ship your order quickly without waiting for bank transfer clearance.

What shipping options are there?

We can offer express shipping (1-3 days) for all UK orders, or flat rate tracked service for international orders (3-18 day depending on location).   Both are fully tracked and shipped via Royal Mail to ensure quick and secure delivery to you.

Can I return my diesel chip if I decide not to keep it?

Sure, we have a no quibble 14 day returns policy - please see the Terms & Conditions page for full details

Where are the chip tuning units made?

Our chip tuning units are made in England at our local assembly factory in Gloucestershire which is fully ISO9001 accredited. The same factory regularly builds equipment for the UK defence and aerospace industry so you can be assured of the quality standard.

Should I inform my insurer if I chip my car?

Yes, although the diesel chip tuning unit is totally undetectable when removed we can only recommend that you inform your insurance company of the modification.

Will a diesel chip affect the warranty on my car?

Installing any third party add-on can cause a raised eyebrow or two at the dealership, and whilst our unit can be fitted and removed (reversing the effect totally and without retrospective trace) we would say it's often best to check and ask before fitting.
