C7 z06 torque management

[atomic vette]

I understand that knock retard is caused by the readings from the knock sensors themselves, thats why i didn't think it was the torque model. The knock retard is the same even if the timing is reduced greatly so I think adjusting the sensitivity of the sensor is the best move. My question has been this whole time, which tables should i adjust to change the sensitivity? Is it common that the sensitivity of the knock system has to be reduced on a modified LT4?

I took Higgs advice today, and raised the torque 2% in some of the trouble areas, and also tuned the VVE out within 1% and the KR is all but gone. There is a tiny blip in a 20 minute drive that I took logging VVE, and when I say tiny, I mean like 1 degree for a second.

Thats really good to hear jmc, which torque tables did you adjust? I will give that a shot in my tune as well.

I used the virtual torque under the edit menu. Find the corresponding table, and up the torque in that area 2%, and make sure you extrapolate the coefficients and calculate the torque tables.

thank you jmc!

thank you jmc!

Thank you, Higgs Boson!

thank you jmc!

Did this help with your knock retard?
I would rather try this first rather than desensitize the knock sensors.

When they say "add 2% to the corresponding table" how do you determine which is the "corresponding" table?
I see -10,0,+10,+20,+30,and plus +40 tables.

How do I know which and where in which I should adjust/add 2% to ?

Thanks Guys

The -10, 0, 10 and so on numbers are spark timing - the timing where your running during the pull... Units should be in lbft of engine torque... Change the airmass or map zones to the maximum your going to see - pay attention to the rpm points up top...

Thank you that helps tremendously.
However I am still not clear and I apologize for not picking this up quicker.

I get that each table is spark in 10 degree swaths.
I get the numbers populating the cells in the tables are foot pounds of engine tq.
I get the numbers across the top for each column of the table are RPM.
I get the numbers 100, 200 through 800 for the rows equates to whatever is selected in the table group drop down for the Y axis. (Airmass, MAP and so on)

What I don't get is what I am suppose to adjust.
1. Is it the max torque I expect to see in each cell?
2. Which row corresponds to WOT? 800 I suppose?
3. Do I adjust both Airmass and MAP? Or are they tied together and when I adjust one table group it carries that change over to the rest of the table groups?

For a theoretical example;
During a single WOT pull my base timing is 22* or so. I am seeing 3 degrees of knock retard from 4800 until 6200 rpm.
Where in the chart would I make adjustments?

Thank you Sir.

Are you getting Knock or Tq management advance?

Thank you Sir.

I went with Boostane with my 2017 Z06. I logged kr even when it was stock on 93 octane.

Sorry to jack the thread, but I've tried to expand airmass and map on my virtual torque table to what my car sees (230kpa). I have to make a change in order to extrapolate, so I just multiply everything by 1, extrapolate, and calculate torque, but it does not save anything. If I compare to the tune, before it shows no differences in the comparison log. Also, once I expand the table to 230kpa, it says I should be making 1400 lb ft at 10*, which I am also not making. Am I saving the tables incorrectly and also once expanded would I need to lower to closer actual torque numbers that the car should see?

[viper139]

I think you have to change all of the tables under the drop down list to match.

[viper139]

Knock Sir. TQ Management Advance is zero.
Stock Z06 just trying to learn more about the "ghost KR" and what affects/controls it. It that's been there from day 1.

Thank you Sir.

Sorry folks hadn't seen the below thread.
It answered many of my questions and should have been where I posted my questions.

The knock sensors need modded some...

You can get it to go WOT before 2500rpms too

I know this I old but Ben care to elaborate on how to get throttle body to open at low rpm in first gear? Seems like this is a reoccurring theme on the forums that it's not straight forward. It's like there is a table that is missing that limits the car only in first gear.
Thanks 👍

Trans, General, Torque Limit, max torque gear vs. RPM (TCM 40750) Change 1 to a higher value. 1000 for quickest throttle opening.

I take it it's something different with a manual transmission? Since no real adjustments on the trans side of things?
Thank you!

It does change the tune if go to TORQUE MODEL> GENERAL > UNDER TORQUE COEFFICIENTS AIRMASS BASED AND SPARK A WILL BE CHANGED
