View Full Version : Learned values in the ECU...how does one go about getting them

other than recording them by chance and hitting the load site/rpm, is there a way to download them and then just apply the changes? Are these maps not found in the codeing?

I'm paranoid about driving my car and not capturing all these spots. maybe I should learn to live with fine learning knock correction values less than 1. there aren't many of them, but it drives me nuts!!

I assume you are talking about viewing the entire fine learning knock correction table? Currently, there is no open source method for viewing the entire table. In Enginuity, the functionality to arrange these values as a 3D table in the logger would have to be added. Then the location in RAM would need to be defined (which would not be hard). I've started working on an app in vb to do this and I'll release it when its finished as a temporary solution until one of the java developers can add the functionality to Enginuity.

Not sure what you mean my values less than 1. 0 would be no correction. I guess you mean negative correction. I wouldn't worry about it too much unless it is a consistent large correction. A serious knock issue would also be reflected in feedback correction and/or the IAM. Absolutely no correction/positive correction across the entire fine learning table (at a given IAM since it is cleared as IAM changes) is not realistic, nor a necessary goal. You are always going to have some negative correction in the table.

thanks for the info. I was hoping I could just o drive for a few days, and then download a compensation map which is similar to the advance timing map.

yes, my goal was to have "0" correction all the time...which I assume is unrealistic. the values I do get are -1.X. I have noticed that I can hold the load and RPM spot and actually watch it slowly add back timing in...so it must have been some kind of false sensing. I will just have to learn to deal with it.

It wouldn't be similar to the advance map. It is based on load/rpm ranges which are fairly broad.
