Knock or detonation is one of the most common causes for failure of any high performance engine. Closed loop knock control when properly configured and tuned can provide a margin of safety to detect knock and automatically retard the ignition timing to prevent damage.
In this webinar we will look at how to correctly approach configuring and tuning this function using a Haltech Elite 2500 fitted to our Nissan 350Z. As always though, the vehicle and ECU is just used for demonstration (we have to use something 😉 ) and the knowledge shared will apply to more than just this specific combination.
Due to the current global situation we though over the next few weeks we'd help keep you guys out there entertained and release some of these Gold Membership webinars to you for FREE to help pass the time.

This is extremely helpful for my current project. It answered so many question I had that I could not find without a significant investment of time on forums waiting for replies about a specific issue with specific conditions. I believe I need to invest into a more expensive ECU so that I have access to a higher level of modification/control and information gathering. Thank you very much for such thorough and comprehensive videos. I enjoy your content very much and I am quite grateful for how much I have learned from you in the short time I have known about this channel.

Hi , it 's interesting to listen to your lessons, especially for a person not particularly dedicated to this, but trying to figure out the setup, I have to use subtitles with translation , since I'm in another part of the world, having a certain equipment of the ECU from Japan and the engine is the most popular 2J in the world , I would like to hear general information about the setup of this engine , maybe you already have a webinar or a narration about the setup of this engine ! Your webinars about the concept and strategy of setting up the internal combustion engine ECU are very clear and give an understanding of where to start!

Very well explained, cheers

@questfor10s 2 года назад

Excellent! Exactly what I was looking for. Thank you Andre! My only question would be if there are more advanced ways to increase the signal/noise at high power levels when noise is much higher? Does knock always occur at one frequency or could monitoring multiple frequencies together increase the signal without increasing false knock?

@yvestheunissen 4 года назад

Would you change knock frequency when running a stock block with forged internals? (MQB platform)

@johnny_gtr 2 года назад

I noticed that when you lifted off, your knock numbers went above the thresholds. How can you stop that registering, if you get the margins right for accleration? Do you remove base timing, or increase the threshold on zero/low throttle?

Hey mate, having a look at my friend's ELITE 1500, there doesn't seem to be a long term ignition trim... Is there something i'm missing?

@dynotechkarachi7481 4 года назад

How set knock threshold for turbocharged car's? Like if my boost target is 30 Psi..

@DP-nr1hz 3 года назад

Andre do formula one engineers set up their ecu the same manner?

Is it worth having knock sensors for a drag car that runs on E85?

@988oguzhan 4 года назад

@@axelriet makes sense i guess i didnt think of it that way. So in order to do knock control we just have to add abit extra timing to see the frequency

@kristiangronberg3150 4 года назад

How about intake temperature? In turbo cars, the flow true intercooler is highly impacted by speed and pack / drag effect driving close to someone in race. The nock limit is by my understanding inpackted which intake temp. Is there a way to tune the spark advance faktoring in the intake temp?

@sexyfacenation 4 года назад

Definitely. Typically there are iat compensation tables. These also exist in factory ecus

i have a knock sound at around 3000 rpm at like 30% throttle, engine at normal temp, (stock hyundai sonata (theta 2.4L) 2010), since it was brand new it's doing it, now it has 90k km, and still doing the same thing. if it occurs, i will change the throttle amount immediately, i can't figure it out ! no fault codes, the car was brand new, i went to the dealer, they tested it ... no clear answer, what do you think is happening ? Oh, i also tried to put some octane boosters ... same thing. it's not a big problem, but it's frustrating me, note that the car is very quick and nice on the road.

@lucasl.dossantos9858 2 года назад

your knock sensor can be with a problem. Consider changing it

@G.J.G.P. 2 года назад

Was it the cracke/ rustle noise? Never heard it before and didnt knew who knock sounds like. Thx for showing us

@hpa101 2 года назад

That is the knock. The constant noise in the background is just your engine, then that crackle over the top is knock/detonation. It will sound a bit different in different engines, but will still be similar enough to help you distinguish it. I am not the tutor here and this video helped me understand what I was hearing when tuning my own vehicle for the first time. It was surprising how much knock was occurring on the factory map, but also being a low strung NA engine it also wasn't really a massive issue for me either. Once you add a turbo or supercharger though that changes quickly! Hope that helps! - Taz.

@G.J.G.P. 2 года назад

@@hpa101 thank you for your answer and further discribing it.👍 since im watching your videos about stand alone ecu tuning, im thinking about it to try to tune my s13 rb26 by my self, once i switch to the emu black i bought. I learnd from you, that i have to tune the ITBs with alpha n. But i still need to get a knock monitor, if i should really do it by my own.
