How to avoid engine knock and pinging
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”.
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.
Suspension settings, lowering and stiffening
On the track your priority is fast cornering and suspension plays a large part in this. Track conditions are quite forgiving and you can make some compromises like using hard suspension and lowering the car for optimum aerodynamics and a low centre of gravity.
This works well because tracks are fairly flat and you do not have a carrier bag full of eggs in the car from your return trip to the supermarket.
