This is probably the most interesting video I've seen on your channel. It makes it very clear why you can't really set up knock sensing without a dyno. It was fascinating to see what's involved in getting the system to sense real knock, but not other, normal engine noise with a dyno, and how you set it up to remove timing when knock is detected, then how long it takes to put that timing back afterwards, etc. Thanks,

Steve, Learned more than I thought about the knock sensors and your tuning. Appreciate the in depth explanation. Warning Steve is the best!

[@raindeergames6104]

Knock frequencies are different for all engines and is actually based on bore diameter kinda like a tuning fork. I tune alot of cars on road and always use my KnockLink headphones. Is a whole different story on the road alot of noise. In South Afirca we have locally made EFI systems and none of them have good knock control so we make extra sure we are safe. If You have a little bit of knock at say 3500rpm at like 27° timing by the time You at 4500rpm it won't knock anymore at te same timing. The higher You rev the more timing it can take because the events are happening faster and that gives more knock resistance. So once I check for knock at lower rpms and find the threshold I know what I can do with timing at higher rpms because it is less knock prone at higher rpm. On a engine like the VW R32 which is a VR6 engine You use 2 knock sensors. One on the front and 1 on the back and You always find that the rear 3 cylinders is more knock sensitive. The Plex V2 is what I believe to be the gold standard of a knock monitor for tuning.

Good clip. It's really cool you explain all the cool stuff you can do with these computer systems.

[@davidotoole-nu4ig]

You can use the individual cylinder trim function to advance the spark one cylinder at a time. You also need to use an oscilloscope to analyze the knock frequency of the engine. Once you determine the knock frequency range of the engine you can select the appropriate knock sensor for this engine. Also knock frequency varies from one cylinder to another. Use the individual cylinder trim to optimize the sensitivity of the knock detection system. Advance the spark in one cylinder only until you get knock in that cylinder, then determine its individual knock frequency. Make sure the knock sensor has a wide enough frequency range to accommodate all cylinders. Sometimes you will need multiple knock sensors in different locations on the engine to detect knock in each cylinder reliably. With crank position information the ECU can determine which cylinder is experiencing the knock and reduce the spark advance only for that cylinder. The more you reduce the spark advance, the hotter the exhaust temp, and the hotter the valves. Also, a leaner cylinder will run hotter and thus be more likely to knock. If you balance the fuel enrichment and spark advance reduction in concert you can optimize the knock response. For example, with individual cylinder EGT information, you can determine how both spark advance reduction and fuel enrichment affect EGT. This level of data granularity will enable the ECU to optimize engine performance with temperature safety maintained across a wide variety of operating conditions and fuel quality. Hope you find this information beneficial!

I'm a tuner and I tune stock base Ecm and Pcms but knock sensors is a must , especially buying from gas pumps.

[@woodyclio]

Steve, when setting up knock how do you know frequency? Is it using the bore dimension calculation? Does the material the block is made out of affect it at all?

[@stevemorrisracing]

It is all trial and error

[@nlo114]

Maybe the knock sensor was picking up the starter-pinion hits as knock? (Sparks = hit, hit = perceived/interpreted knock. It may be worth putting the video side-by-side with the laptop knock-trace to see if they coincide)

[@Map71Vette]

How much power do you think that engine could make when tuned and running on race gas? Would it beat the 5k mark or would it need more things changed to withstand the added power?

Would be interesting to see more of this giant jetski looking boat. Also interested in how these high horsepower centrifugal supercharged engines go in marine applications in regards to sudden engine rpm drops when going over waves/chop. Is it even an issue?

[@jamiealexander6585]

Big Black Hemi question in a boat would the knock sensor have an issue with waves? The hull of a boat smacking the water for example. Just a question more or less

[@theatomproject007]

No. Knock Sensor = High fidelity Microphone (technically an accelerometer) so the dynamics of the sound made when a wave hits the boat would be completely different sound than what engine knock sounds like. That's why Kyle hitting the engine with a hammer is a good analog for engine knock and not his fist or head. (though I bet they felt like there were banging their heads against the block for the BBH :) ) Not Steve's fault but the signal he is displaying for the knock signal is not really what it looks like. In fact I don't know what that signal is actually showing since the raw signal would be a sinusoidal sound wave that crosses over 0 mV just like any other sound wave. [If I had to guess I would say it's the RMS for the whole signal] For normal engine operation there would be a baseline sound level across a whole range of frequencies, but when engine knock occurs there will be a peak at a specific frequency range. Commonly for this type of signal the sound wave is processed in a way that instead of it displaying sound over time it displays sound over frequency in units dba.(think noise meter app) If you have ever seen this type of Power Spectral Density plot it looks like an equalizer display for a car stereo and each 'block' represents a given audio frequency range being measured. In the case of a PSD used for knock sense it's made up of many more blocks that divide the signal into hundreds or more smaller segments that are then each measured for their magnitude. When the magnitude at the correct frequency exceeds a certain level (one of the inputs in the EFI system) then it gets recognized as knock. So normal engine combustion events are low frequency, but actual knock is a very high frequency. Water hitting the hull of a boat would also be a very low frequency compared to the normal engine sounds. It's actually common on many engines to just put in standard foam earplugs while running on the dyno and they do a great job of blocking most low frequency noises, but still allow you to hear engine knock. As for OEM Car Manufacturers they actually use a combination of high frequency pressure sensors (Kulites) that go directly in the combustion chamber and single plane accelerometers together to establish a given engine's baseline noise level. Then once that information is established a known frequency and magnitude can be determined to be knock so that even the simple $100 knock sensor can sense when the engine is knocking. Along with that they can build up baseline engine noise and vibration levels that are so precise that abnormal noises can be identified all the way down to a given bearing or accessory being driven by the engine. This is actually a very common measurement method in Aviation propulsion where most aircraft engines have a Plane 1 Accelerometer that is used to measure the rotational noise and vibration of an engine assembly which is fed the the FADEC (Aircraft engine controller) to signal an alert if the engine is not performing within it's nominal limits... Or even more amazingly... how long an engine has loitered in a given noise range which triggers mandatory maintenance. Imagine having the ability to catch valve float or crank vibrations at a given RPM and make sure your engine never operates at that RPM for long... Yea, only costs a small fortune in instrumentation and software...

About the gear driven blower: cant you turn the gearbox 180° so it steps up? In boats that is done. Mostly the forward/reverse box is straight in and out. But the reduction has a step like an ,,doubler,,or an transverse box. Normally this step goes down. So your propellorshaft ends, bolts to te combined reduction/transverse box. Because of the gears a step of ? inches is going up. At least on the standart configuration. So the engine has to come up that ? inches. With you its the other way arround, its stepping down. On some boats the engine will get to high and dont fit under the floor. A few brands or type of boxes can be 180°(no not playing darts😂) so the step goes up. Is there ever experimented with the blower drive like put a cvt in? Or is a fixed ratio the best option?
