By advancing the timing (early ignition of the spark), the probability of producing knocking increases. Although efficiency is of course a priority for manufacturers, this is also the case for reliability. The experiences show that it becomes a little tricky when doing it yourself. This converts much of the pressure generated into useful work. Finally, you want to make sure that the peak pressure occurs when the piston is very close to top dead center. If the ignition timing is too late, you are wasting energy. The piston tries to compress a mixture and the combustion provides pressure to push it down. If the ignition timing is too early, there is a force opposite to what the engine is trying to achieve. When this spark is ignited is of decisive importance.
The cylinder is filled with an air-fuel mixture and the spark plug is waiting for the engine control signal to ignite. Think of a piston on its compression stroke.
The idea behind the ignition timing is simple. The idea of chip tuning sounds a bit too good to be true: More PS without any physical changes? Is that really possible? In any case! That’s how it’s done: Chiptuning optimizes the ignition timing If you are interested in motor chip tuning and want to know everything about the process and how it works, then let this article guide you! We’ll show you the advantages, disadvantages and costs and tell you if it’s worth it to do it yourself.
