Knock / Pinging / Detonation | What does it sound like? [FREE LESSON]

Sooo, if your engine sounds like a geiger counter you are F*cked ! 😂

So what ECU do to prevent knocking (or reduce harm from it)? Advance timing even more?

If the engine knocks due to low octane fuel, will it generate any diagnostic trouble codes (DTC) in the engine report? If so, what would the code be related to engine knocking?"

Hello there, if I want to add one knock sensor to my engine, where should it efficiently be placed.

It sounds like shaking a bunch of bb's violently in a coffee can. The first time I experienced it was with bad gaa and I thought gravel was flying up off the road and into the underside of my van!

So is this the same sound I should be looking for if using det cans?

Why would you not let us listen to the engine normally? Helpful for us people without all your equipment.

Wow, coming from someone with 0 previous knowledge, that was very informative and helpful. You’re an amazing teacher

Do another 1 please Andre, With a Big Turbo and Antilag. Be Interesting to see how Antilag effects knock levels.

Hi sir if my link come out 122eror code injector max duty cause from fuel pump can we clear code by remove battery terminal?

terrible

Since I can't hit like more than once👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

This is complete crap. You didnt show anything on how it really sounds in real time

KNOCK THREE TIMES song by TonyOrlando!
Here's my favorite & depressing knock n pinging story that I or dozens of techs could never fix. Had a 1991 Cadillac Brougham 305 Chevy TBI LO3 motor that would ping at WOT (sounded like a glass jar of marbles under the hood that's how loud it was!...a little at part throttle. Would only stop on 100 octane. Did every trick in the book....had to run the coldest Delco plug & still saw aluminum peppering on the porcelain & eventual burnt grey melted spot on center porcelain. Used to make my rounds to 4 Caddy dealers back then & they couldn't figure it out. One of the old techs said I was 6 months til warranty expires..... drain oil out, drive it til it knocks, put oil back in & get a new short block which would then verify if it was mechanical or fueling/ecm! I'm sorry I never did it....drove me crazy, & now there's all this new diagnosis technology to verify that problem I lived with for years...... One tech figured the factory resurfaced the heads making high compression ratio with 180+psi.

how rotary knock sounds?😂

Informative and valuable. Thanks.

I have tried to use knock ears on the dyno and found that all it did was add to the amount of noise rattling my brain. I just ordered a knocklink and I'm hoping it will be a more useful tool.

So, how did you fix the knock issue that occurred after opening the throttle? 😮

I have one question for you, I have a problem that knock happens at high revs, over 5000rpm it happens, and below 5000 everything is fine, the fuel mixture is excellent 12, lambda ok, fuel pressure ok, fuel pump ok, im driving on Vems ecu, so what do you think is the problem ?

Anyone else not hear anything?

Is the hissing sound what knocking and pinging sounds like? Because I don't hear anything different.

What knock detector was in your opinion the best you have used? I’ve seen many tuners use something almost like a medicinal amplifier with a hose.

What? I'm hard of hearing and during your "knock" sounds, the video was entirely silent! Hows a deaf person living on their own with no friends to call upon going to know? I didnt hear anything! You gave the noise of the engine without knock, but omitted the engine noise entirely during it! Is there not a way to film knock with engine noise? OR because of my hearing... Engine noise or not, I wont even hear it anyway??

Ive never heard a engine that sounds like that :/

That sounds more like crickets 🦗.. not what knocking would sound like w your ears.

Sounds like crickets

what is your opinion on the Alientech KTAG?
Seems like a good entry level model to play around on a beater car

Sounds like crickets outside in the summer 😆

I didnt hear anything but crackling like valve chatter.

Knock, pre-ignition or pinking sounds like light stones rattling in a baked bean can. I didn't hear that noise in your demo even with headphones!

will retarding help reduce knocking?

I was trying to figure out what was annoying me about this guy. Hes not only knowledgable but also very patient and super clear when he speaks. When he interviews people he knows what questions to ask tuners cause of his viewers I love it. Then I realised what it was. He doesnt annoy me, its where hes from that annoys me. NZders talk with staccato so it doesnt flow. Keep up the great work HPF. Im waiting to buy my Haltech Elite 1500 then Im gonna soak in all that juicy info from your courses. Pretty cheap too considering.

Another quality HPA informative blog post. Always awesome content 👍💯 Aussie Fan 🤟🆒🤣

New video title: “RELAXING ASMR cicadas and calming NZ accent” you’ll go viral thank me later 🙏⚡️

Is this part of ecu tuning course or EFI Tuning course package?

i always describe it sounding like when you eat popping candy like pop rocks

Andre blinked 84 times in the first speaking segment.

My 132cc moped does this sound when I set the ignition timing too advanced 😅

Im looking for a tuner in dfw area for a micro squert car. You dont happen to have one you recomend ?

One more tist

Thrishhold 😂

I have seen people claim you can see spark knock by the exhaust. If this is true how does it effect the exhaust look?

That is why the engine gods gave us water methanol 😆 🤣 😂 and it was good 👍

My hears are still ringing. Super informative video. Thank you for sharing your knowledge...

Thanks sir

i learned nothing :/ i hear nothing

My boy blinked like 130 times in 10 second 😂

His 👁 are knocking...

Right, sounds exactly like someone knocking on your door. Right. And my flatulence sounds like Mozart.

I remember in the 1990’s I heard of a few cases where the mega bass competition level audio system in the vehicle would trigger the knock sensor and the timing would retard to the point that the vehicle had very poor performance.

To me knock strategies deserve a lot more attention than we give them. In racing or wanna be racing, to be competitive we must push the engine all the way to the limit and knock will be the indicator that we are there.
