this will help me to understand the Ignition Timing because there is no ECU Tuners near my location. Ignition Timing is the only thing i can't understand on ECU Tuning. 🤣
Does ignition timing change once the engine comes up to operating temp? I have a motorcycle that runs fine when cold but has a hunting idle once the engines warm. Previous owner had an aftermarket ignition module.
I have a Polo 6N, 1.4 mpi, the standard ignition timming idling is 6°BTC according to the marks on pulley , but the engine is sluggish somehow here, if I turn the dizzy few degres in advance I really get it snappy. This engine employs a single Hall sender located inside the distribuitor body, wich delivers the timming signal for injection as well, so advancing the dizzy won't advance the moment of injection before the intake valve opens, with bad effects over mixture?
hey got a question for you i got 1990 blazer 5.7 tbi had engine rebuild about month ago got a few up grades bigger cam so i had to get my computer chip tune to raise fuel and timing on the chip i change pressure regulator and adjust that the cam i have in there is xe 262 h comp cam the block was 30 over.and i still have the factory swirl port heads i should had put some vortec heads on there...but for some reason cant get it to run right just dont have no power and im getting a ping sound from engine and #6 had oil on spark plug threads only the rest of plugs are fine i dont no where im getting the ping sound dont no if the oil on the spark plug have anything to do with it or something with the fuel and timing is not right..
my tuner says 0-2000 4000-6000 6-8000 and the degree changes go from 0 -- -14 do ca n i set all areas to -2 degrees or any degree as long as i stay under 10 or is it just whatever urns better
The situation that you describe is very common from mid-to-high load. I would dare to say that about 50% of the map is knock limited on natural aspirated engines. With forced induction, this percentage is way higher since engine load can go above 200%.
I wanted to watch this video because I'm curious if boosting a 392 could be safer on the engine if timing is retarded. Maybe that can be more gentle on the engine but then again, it might not make any net power gains.... *sigh
Thank you. I have a doubt. You said spark timing is retarded as the load increases and timing is advanced as rpm increases. But doesn't this contradict each other since the rpm increases as the load increases (% load = current airflow/Max airflow *100).
rpm is just how fast the engine is running, load is the resistance to the engine running. A car in neutral rev'd up to red line would have tons of rpm but no load, and a truck pulling a trailer at 1000 rpm would have a rpm but lots of engine load.
Why does anyone even go to school anymore? What I just learned took me 2 weeks of 45 minute classes in school. And I didn’t even retain the information because here I am, looking it up. School is for suckers. Drop out and learn a trade. If you need to know how to spell or do math, google/RUclips it!
All these videos showing you graphs after graphs after graphs not one video shows you how to actually do it mechanically. Someone walking into this video with not much knowledge is probably going to end up with a ton of questions then answers. I'm still waiting for someone to actually do a fucking detailed video translating all this in real time. Guess never gonna happen as always 🤬
nice video, thanks for sharing. I have BMW M4 (S55 engine) and still thinking of ignition timing corrections which I can see at my datalogs. It is random, cylinders are changing, the difference is usually up to 3 deg.sometimes up to 5 deg. Some tuners say that this is caused by low fuel quality so I have tried all branded fuel from 95 to 100 OCT and the datalogs are always almost the same. Is this a standard engine behaviour or should I look for some problem? Thanks, Richard
Excellent!!!! Best vid. Def saving ! Ty! I just didn’t understand in the beginning when u said advance but it looks like your retarding . If advance does it mean to turn the timing in the direction of the engine movement when turned on ? So does that mean the spark is sparked when the piston is past the top dead center ?
❤❤❤❤❤ Thank you very much dear....i was wondering if i could get this much clarity on the subject in one single video and here i go ❤❤❤ Thanks again dear
Spelled ENGINE wrong.... And 10* bTDC isnt farther from TDC than 15* btdc....🙄. And it needs to be said that: the Explosion takes the same time at Idle and 7000. But otherwise, great video
I let a friend use my distributor off my tuned Skunk 2 99’ Prelude to check his H22A non tuned Prelude which was not firing on all cylinders,and now i’m running too rich! Should i just mess with the distributors alignment? Or have the tuning completely checked? Thanks!
Why overheat when delayed timing is used? makes no sence or is it because of the exhaust gases have not enough time to leave before ex. valve closes which means that "old" hot exhaust gas is caught in comb?
I've worked on cars my whole life and this video still helped me visualize whats truly going on better. Well made. Thank you.
Extremely helpful.. though music was touching roof but the info was reaching sky. Thanx Sir.

Hahah that comment was priceless. I will try no music on the next video. Thanks for the constructive criticism 😃
Dang I could barely hear what he's saying.
This guy reads poetry. Made me tear up...
@@gianlucasturla6929 :D thanx man...
Came across this video, whilst researching Ignition Timing. Nicely done, thanks
It would really help if you do not add music in the background
Beautiful video! Just learned literally so much in that 5 minutes. Please continue making content that was very well done!
Absolutely the best video I've seen about ignition timing. Liked/Subscribed! Please keep the vids coming. Thanks
Best explanation I have ever seen on the subject.
this will help me to understand the Ignition Timing because there is no ECU Tuners near my location. Ignition Timing is the only thing i can't understand on ECU Tuning. 🤣
Incredibly well made. Cheers.
A very thorough presentation. 👏
Thank you for the kind words! 😃
Thanks for the informative video as you mentioned it's not as simple as people think.
Super useful! Clearly illustrated, no BS. This is the type of content we want from youtube...
Idk, the music was some pretty annoying bs to be quite frank
I love that graphic content, keep the good work, thank you :)
Very well explained. Thank you for the lesson.
thank you , very useful explaining
helpful in understanding the concept..thank you
Simple and clear. Thank you for sharing!
Amazing! So much information packed into 5:30. Thanks man for spreading knowledge. 🧰🪛💪
Thanks, very nice explained !
Thank you!
Knock sensors are a miracle
Nice explanation. Thank you man.
Huge many thanks 👌
A1 video
Very good info, but the music has very bad effect, hard to hear your voice.
Thanks
I will try to do no music on the next video 😃 Thanks for bringing it to my attention
take note algorithm overlords, this is a good one
best video
Brother why are u not uploading videos
Great info and delivery!, music wayy too loud tho
Very nice! Seems like IG timing is the real tuners secret. A knock sensor help?
Liked and subscribed. More content please!
I have something on the works! Hope to publish it soon 😃
You forget to mention the single most important thing that effects Ign. Timing. Fuel atomization and wet flow thru the intake tract.
Well what are the values in the table ? A/F ratios or degrees before TDC ?
Degrees BTDC at which the spark occurs.
Are the axis defined correctly? Shouldn't be that y-axis = Engine Speed and x-axis = Engine Load?
Does ignition timing change once the engine comes up to operating temp? I have a motorcycle that runs fine when cold but has a hunting idle once the engines warm. Previous owner had an aftermarket ignition module.
Excellent explanation. What's the name of the song by the way?
Best start up = II spark - half wrls || wire EFI xtra cellz! I.e. fuel cells!
Very good video... I am sub 👍
Nevermind , i watched it again it its before it hits top dead center so that the spark has more time to burn the fuel.
Is 12.5 to 15 degree fluctuation normal spark adv at idle for Toyota corolla 1.8l engine?
The music is louder than your voice at some points. It makes it difficult to hear everything bc your voice is so soft. But thanks for the vid.
My car is pulling -10.5 degrees we got it down to -8 how tf do we fix it
I have a Polo 6N, 1.4 mpi, the standard ignition timming idling is 6°BTC according to the marks on pulley , but the engine is sluggish somehow here, if I turn the dizzy few degres in advance I really get it snappy.

Why the music?
hey got a question for you i got 1990 blazer 5.7 tbi had engine rebuild about month ago got a few up grades bigger cam so i had to get my computer chip tune to raise fuel and timing on the chip i change pressure regulator and adjust that the cam i have in there is xe 262 h comp cam the block was 30 over.and i still have the factory swirl port heads i should had put some vortec heads on there...but for some reason cant get it to run right just dont have no power and im getting a ping sound from engine and #6 had oil on spark plug threads only the rest of plugs are fine i dont no where im getting the ping sound dont no if the oil on the spark plug have anything to do with it or something with the fuel and timing is not right..
What is ENINGE LOAD ? 3:18
my tuner says 0-2000 4000-6000 6-8000 and the degree changes go from 0 -- -14 do ca n i set all areas to -2 degrees or any degree as long as i stay under 10 or is it just whatever urns better
dyyuuuude, just seeend it braah
Again music is in the way of learning.
3:20 engine typo
in what situation would you see the knock limit happen before mbt?
The situation that you describe is very common from mid-to-high load. I would dare to say that about 50% of the map is knock limited on natural aspirated engines. With forced induction, this percentage is way higher since engine load can go above 200%.
what is the best ignition timing at high rpm?
Only considering speed and load, the optimal ignition timing increases as rpm increases, and decreases as load increases.
Great content, but that music makes it very tiring on the ears
Creating map is a good idea but how you record the info for it is not explained at all.
That’s an excellent idea for a future video!
Simplified? Prat!
KOOL
background music is loud
Thank you for the constructive criticism. I’ll try no music on the next video.
The background music is a distraction
That's great and all but could you spell "engine" correctly on your sketches??
E N I N G E
I wanted to watch this video because I'm curious if boosting a 392 could be safer on the engine if timing is retarded. Maybe that can be more gentle on the engine but then again, it might not make any net power gains....

Don't talk about fuel burning as an "explosion." I assume you know better than that.
Why not
Kill the tunes🤣
Your not explaining engine timing but explaining theories and university complexities about engine timing. You are way off the road.
All these videos showing you graphs after graphs after graphs not one video shows you how to actually do it mechanically. Someone walking into this video with not much knowledge is probably going to end up with a ton of questions then answers. I'm still waiting for someone to actually do a fucking detailed video translating all this in real time. Guess never gonna happen as always 🤬
No offense i could barely understand your tongue
Fuel air ,spark and you forgot compression!
Why the distracting music???? Could barely hear the speaker over the noise. It contributes nothing.
Thank you pointing improvement opportunities!
5 minutes video but watching it takes 20 minutes
😂😂
Amazing video it explains the concept of why tuning is so important especially if you are using an engine for performance base
Get rid of the music!
Seriously the best and complete concept explanation I've ever watch.
And I have watched millions of explanation video
thank you for the kind words!

Why people always have background music. Fu@&
If you RAISE YOUR KNOCK limit say its 20 bri g it to 24 does thatmake more power or go way 18, the other way?
Easy, find fastest 50-80 time with a stopwatch
REMOVE THIS USELESS MUSIC PLEASE!!!
Why u are not uploading videos

Thanks again dear
videos ok..but its not simplified most people wont know what the fu654k hes talking about
Good explanation and very good illustrated, but please bring down that fkn music
A lotof music film
Spelled ENGINE wrong....
And 10* bTDC isnt farther from TDC than 15* btdc....🙄.
And it needs to be said that:
the Explosion takes the same time at Idle and 7000.
But otherwise, great video
No secrets here.
I let a friend use my distributor off my tuned Skunk 2 99’ Prelude to check his H22A non tuned Prelude which was not firing on all cylinders,and now i’m running too rich!
Should i just mess with the distributors alignment? Or have the tuning completely checked? Thanks!
Timing is advanced at cruise conditions because the afr is lean.....leaner mixtures takes longer for combustion.
loved the chart saying "Eninge" either way AMAZING VIDEO AND FANTASTIC EXPLANATION GOD BLESS YOU
modifying ignition timing is too scary
Concise but informative. Well done 👍
Great stuff my friend!
We need more videos!!
Great info. 👍👍
Nuts
I subbed. I hope you keep making these awesome educational videos. Cheers.
I’m trying to get back to them! Thanks for supporting! 😃
great info man
Thank you!
