Knock Control only goes down to .50

Post by Jasonvictory86 »

Hi!
My Knock Control Value only goes down to .50. It looks like a software limitation and not my driving habits.

Can you take a look?

Thanks!

Right. That's not something we change in Honda's settings. You have access to change knock retard and ignition values, so it's not relevant.

Would I set the Knock Retard table to 0 negate it? Or would setting to 5 compensate the the control value of .50?

Also, what happens if I do have a knock? I thought the car would pull timing if knock is detected by default.

Thanks!

I don't think you've read the help section for this logic.

I did read it but it is still confusing.

How did you get the "knock limitation table value" to 2.0 in the example?

In the example picture, the only value with 2.0 is at MAP .2bar @ 5000 rpm.

It says "Say in this example that we have", because it's an example.

Ok, I re-read it, took a look at my logs with actual ignition, and got some good ol' pen and paper and makes more sense now you I know the value of 2 is just an example.

One other thing, I noticed there's no boost table visible for my Fit. Is that something that can be added or is the last value (.02 psi) carried throughout the rest of the boost table?

Thanks!

As the tables are interpolated, if you exceed the last column that is what is used.
