Love the explanation. Saved me a lot of time and money paying for tuning courses. I understand how things work, but don't know everything about how HP tuners works lol. Thanks
well done mate, though I would probably not go by the max values but do a couple passes using the averaged ones, just a thought otherwise your High Octane table will diminish and resemble the low Octane one too much
I believe there is a flaw with this method that needs to be accounted for. The spark decay rate will permit knock retard in other cells, where there may have been no knock at all as the spark retard decays down to 0, unless of course the scanner is programmed to omit logging knock in a state of decay. Smoothing should probably be mentioned also, as a 7 deg subtraction next to a cell with no correction is going to make for a pretty jagged spark table, not to mention some PCMs will go haywire with that kind of coarseness. Some beginners may not be aware of this and follow the above instructions as is and end up in tail chasing trouble.
How do you tune this out? I don't wanna go tuning the sensitivity if I dont have to though I may have some reverb from modified exhaust or all kinds of crop banging around besides the pistons... lol For real though, what would you recommend to account for the decay? Im seeing in my tables no knock then after the cell hit has passed other cells, it'll show up as knock a few seconds later in the same cells it detected zero knock.. Pain in my a$$.... Thanks for that insight
did you ever find it, it's called Cylinder Airmass and you have to add it to your Channels list first on the left in order to later add it to the graph view on the right
Now how do you get rid of false knock, cause I can subtract 3 times the timing as there is knock and it will still knock same amount. I'm thinking its clutch chatter at this point. Pretty well always in cylinder 4 on i4
We have some other videos that may help you. ua-cam.com/video/ScjfTGLnpPk/v-deo.html ua-cam.com/video/S8L9IUbt7ag/v-deo.html and an article on our site thetuningschool.com/blogs/news/knock-knock-article. Feel free to contact us if you have any more questions!
@@TheTuningSchool well based on this, my knock is false. I have reduced timing , added fuel, added ethanol to my tank for higher octane and I spray about 1000cc meth , I still get random knock here and there in boost. Not usually though,the more I get into it it goes away. And the light throttle stuff is still there randomly. Have run like this 3 years and its still going lol and I never heard an audible ping. So thanks this really helps ease my mind
Is it worth shortening the knock retard decay for this exercise? Otherwise couldn't the decay rate have you permanently retarding cells that do not need it?

Haha. No problem. Feel free to contact us on our website, via email, or by phone if you need help!
i would do some interpolation around the areas that was changed or you might get some bucking at certain rpm's

Hi , thanks for the informations ,
Please can I do this to kia and Hyundai brands made in US?
Best regards
I have a 2019 challenger 5.7 and i don’t see low octane/high octane. What other tables could i use in place of? Thanks ...
Another great video
Why thank you for watching! And thanks for the feedback
VERY Helpful! Thank you!
You're welcome!

I don't have the airmass channel! Yet that is what I need for my spark table... Any help would be great!

what is the most spark advance an LS should have cruising around 2,000-2,500 rpm?
could be upwards of 50 degrees cause it's light load
When are you going to do some videos on the hemi's like the 05-09 chargers etc?
Our HEMI course will be out this year so STAY TUNED!
What units can we log in the high octane timing chart to determine which amount of timing gives us max torque?
What if you have no knock but some ignition correction between 3.5k-5k rpms. How bad could that be over long term
Amazing. 👌🏽👌🏽👌🏽👌🏽
Thanks for watching!
Can you make a custom tune for my RIPP Supercharged 3.6?
Just got it installed on my 2014 Charger and I’m experiencing a lot of stalling in the low rpms
Is it worth shortening the knock retard decay for this exercise? Otherwise couldn't the decay rate have you permanently retarding cells that do not need it?
can we use same technique at wot kr ?
Yes!
