Title: FLAT SHIFT CODE MODIFICATION ME17
Post by: alessandro244 on May 22, 2026, 04:05:11 AM
Hello everyone, my name is Alessandro. I recently learned how to dismantle code and create small patches.
I think I'm on the right forum.
I'm working on med17.3.0 with an existing flat code. The problem is that NLS only activates when the threshold is set, and it doesn't take the rpm value when I press the clutch pedal.
I'd like to modify the code to take the rpm value only when I press the clutch.
I didn't want to publish the entire code out of respect for its creator; I only posted the part where I think I can make changes.
I believe the code was written by someone on the forum ::).
I apologize for the variables, but I identified them in Italian and hope they're correct.
Anyway, my idea is to create a variable that contains the revolutions per minute (RPM) when B_kuppl is active and insert it in place of NLS_ATTIVAZIONE_RPM.
I'm available for any further questions; I'm eager to learn.
the code is too long so he inserted it into a text document

I'm sharing my little patch (still not working) and I'm hoping for some expert opinion. *************************************************************
