The modern diesel engine has come a long way since the old smelly noisy almost agricultural units of years gone by. With the advent of high compression engines, turbo chargers and direct fuel injection at phenomenal pressures we have a range of diesel engines that out perform thier petrol counterparts and return better fuel economy.

The big plus is that with a simple remap you are able to dramatically increase the performance and also generally get better fuel economy.

We look at all aspects of diesel engine tuning and suggest that you join our forum for more information about the world of high performance diesels.

Stage 1,2,3 remaps and mods

We wish people would stop using stage to describe a tuning option or plan but while they do we’ll define here what we mean and expect when we talk about the term.

We get asked so much about this that we wanted to spell out what we mean and most car modders mean when talking about stage 1, 2 or 3 remaps and mods. We look at the various stages of remap available and the mods that would work best on stage 1, 2 and 3 upgrades. Each level of remap carries risks and drawbacks so we will outline them here.

Diesel Tuning for maximum power and torque

From a diesel perspective, anything that isn’t turbocharged is a waste of time from a tuning point of view. Similarly, anything that isn’t using electronically managed direct injection is a pointless tuning proposal so we are somewhat limited to modern Turbo Diesels.

Get rid of those two ointment bound flies and things get more interesting

Remaps for diesel engines

Our members frequently talk about their latest mods and power figures. Many of our members have remapped their diesel engines and boast of more power, better economy and unchanged reliability.

But do the claims live up to reality? What sort of power figures can you get from a diesel remap? Diesels have really come so far in a very short time.

Tuning boxes

Tuning boxes are often slated because there are so many rip off devices around. We look at the truth about tuning boxes and help our readers identify the piggy back ecu’s that are worth having. What does a piggy back ECU do? How do they work and are they worth buying?

Alloy wheels and their impact on handling and performance.

Some rally style alloy wheels are lighter – (less weight = more speed) and also are designed to increase the cooling of the brake disks.

Some designs hold up better to being curbed than others and some break very easily when hitting a pothole or curb at speed.

Always go for the best quality alloy wheel that you can afford and read the reports and reviews. If you do go for a different overall size you must get the suspension and tracking realigned to avoid uneven wear under acceleration.

Lightening the flywheel

Lightening the flywheel – the flywheel works in a similar way to the wheel in the toy cars you used to rev up and release and let it zoom off. The heavy wheel located between the engine and the gearbox builds up rotational force with speed and momentum.

Effectively storing the energy and helping the car resist changes in engine speed – good for cruising at a steady speed but bad when you need a fast engine response.

Big valve kits – larger intake valves.

The heads primary job is the mixing of fuel and air and delivering this to the combustion chamber.

Any turbulence or drag can restrict the air flow into the engine starving you of power. So this TorqueCars article will focus on the intake valves and how they can be improved.

The aim of head tuning is both to maximise the amount of air and fuel that gets into the engine, and to improve the mixture.
