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.
Power gains from a sports catalyst
Catalysts are a vital component in our modern tree hugging environmentally conscious society. First TorqueCars will look at what a catalyst does and how it works.
A catalyst is actually a term used to explain anything which accelerates or performs a chemical reaction. In a car the exhaust fumes are fed through a matrix of ceramic honeycomb lined with precious metals.
Ceramic exhaust coatings and exhaust wraps
Under bonnet temperatures are one of the biggest performance killers around.
Quite simply, you want your engine to be sucking in cold air as this carries more oxygen and will allow you to burn more fuel.
The exhaust system is one of the contributors to under bonnet temperatures. You can therefore lag the exhaust to help prevent this heat soak into the engine bay.
Remapping the ECU – remaps benefits and issues Back in the good old days – the task of timing the ignition spark was performed by the distributor. The greater the RPM, the more the timing would advance.
This did a reasonable job but for the most effective power you would need to vary the timing to a greater degree than a fixed ratio advance curve. The electronic ignition system was borne.
