ECU Chip Tune - Ignition Timing - Increase Horsepower

How to increase horsepower through ignition timing. How does ignition timing affect horsepower? Should an engine advance or retard timing to increase horsepower? This video explains the logic behind ignition timing tuning.
NOTE: "Knock occurs when the peak of the combustion process no longer occurs at the optimum moment for the four-stroke cycle." ~ Wikipedia. What happens when the timing is too advanced is the maximum pressure occurs before TDC, which pushes down on the piston when it is still coming up. This is what you are attempting to avoid when advancing timing.

One thing I found out when looking into timing experiments for my Miata, the higher octane gas you're running, the less likely you are to have knock at higher timing degrees. For instance, my little 1.6L engine will knock if it's running on 87 with the timing advanced from 10 to 12 degrees BTDC, but if I run 93 octane, I can advance the timing all the way to 18 degrees before it starts to knock. Just thought I'd add that.

@oldfashionedwrx3574 7 жыл бұрын

VoraciousPhantasma that's because octane is the measure of resistance to knock. if you use higher octane fuels you can run more parameters to generate power before you reach the knock threshold.

@ryanlee112 7 жыл бұрын

thats because the octane of gas is the resistance to knock. e85 has around a 113 octane thats why people can make more power with it

@Bassix92 7 жыл бұрын

Jared Tate I thought octane was resistance to detonation/pre-detonation, requiring a higher flash point with higher octane ratings thus ensuring that combustion won't happen simply from the pressure and/or heat that occurs from internal combustion (unless it's diesel which runs off compression once started) but from the actual spark plugs, which in turn allows for more aggressive and advanced timing and tuning setups. That allows a bigger safety buffer against knock the higher the octane used because it's rated to not combust earlier than desired. that's what I was taught growing up and why I always run at least 91 just for the added peace of mind and it actually increases gas milage because it burns more efficiently and the ECU (stock or not) picks that up and adjusts the AF ratio accordingly

@tonytober 6 жыл бұрын

We refer "knock" to the sound that detonation/pinging does when the engine is running. We're all talking about the same thing here, so you're right.

Perhaps I used the wrong terminology, but hear me out. "Knock occurs when the peak of the combustion process no longer occurs at the optimum moment for the four-stroke cycle." What happens when the timing is too advanced, is the maximum pressure occurs before TDC, which pushes down on the piston when it is still coming up. This is what you are attempting to avoid. Wiki calls this knock, though perhaps incorrectly. Regardless, the principle holds true. This is NOT pre-ignition.

It can be as complex as you desire. You could absolutey change the timing characteristics (as well as others) depending on the position of the gas pedal, as well as other factors like RPM, etc. Older cars are a bit more static, but I would imagine hardly any new cars don't have more dynamic programming.

The delay for anti-lag isn't to increase horsepower, it's to increase the amount of exhaust gas temporarily in order to maintain boost, allowing for more pressure in the exhaust manifold rather than in the cylinder.

Ignition may occur before TDC, but you want the maximum force created (by the expansion of the igniting air/fuel mixture) to occur once the piston is moving down.

@EngineeringExplained 11 жыл бұрын

If it's electronically controlled it's not going to change the timing unless something tells it that it needs to. For example, if it knew that the mixture was going to knock, it may alter the timing (or air/fuel) and try to compensate and eliminate the knock. Not sure what to tell you, check for engine codes and see if it spits anything out. Most auto parts stores will read it for free.

That's not what I was intending to say. What I'm saying is detonation occurs at a time when the maximum pressure will be reached before the piston reach TDC (while it's still moving up).

@EngineeringExplained 11 жыл бұрын

It's because you can increase the boost simply with a tune with most modern turbocharged cars. That means you can easily increase the amount of air supplied to the engine, thus can use more fuel and create more power. With NA cars you can't really alter the amount of air that comes in, just the amount of fuel, without actually swapping components.

I somewhat know the very basics of car mechanics but your videos cleared out a gray areas and taught me new things. Can you achieve power gains by ONLY adjusting the timing of an engine, while other ECU-controlled variables (eg A/F ratio) are kept the same? This would also translate into increased efficiency as well, right?

@Madds5150 10 жыл бұрын

In regards to the setting the timing back short of maximum HP/TQ to prevent knock, in most cases there are two ways to deal with it though one is more preferential IMO... Enrich the mixture to slow the burn of the flame front... or the better option of raise the octane rating of the fuel. To make maximum power in an engine you tune the ignition advance curve for HP/TQ then tune for fuel to allow that timing curve. Great video BTW!

@ChroniclesofKToyoda 4 жыл бұрын

Twin spark systems are commonly just used on poorly designed (slow burning) combustion chambers. However it can be used to lower time to establish a sizable flame kernel more quickly, meaning less degrees of burning "B"efore TDC & more AF mix for burning "A"fter TDC, AKA, more fuel being used for power.

@EngineeringExplained 11 жыл бұрын

Perhaps, based on my chart, though mine is certainly not representative of all engines. If knock is fairly easy with a certain design, they will likely choose to be overly cautious with the timing.

Just before, actually. Because it won't instantly get to high pressures, it requires a little time to spread the flame.
