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.
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.
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
So what exactly is engine knock and how dangerous is it? What causes engine knock and how can it be avoided?
You may notice a knocking or rattling noise from your engine or a sudden loss of power under full throttle.
Immediately back off the throttle and only use low rpm engine speeds until you can get the engine investigated.
The chances are that you are suffering from a condition known as “engine knock”.
