10 Cent Tuning: Why Pins 2 & 3?

Hello, diesel mechanics!
Why are you using a 10-cent tuning on pins 2 and 3 instead of pins 1 and 2?
The pins 1 to 3 are connected to the sensor for the control slide position.
The tuning box I'm currently examining activates pin 1, meaning the box disconnects pin 1. Speedbuster and Küberl are connected to pins 2 and 3, with Küberl functioning exactly like yours.

PS: Why not on pin 1?????

Hi ,
The drive is less sensitive to variations on the variable side (2,3). Even a small difference of a few ohms on the reference side can cause the motor to jump into emergency mode. Even small resistors (22 ohms) can cause noticeable instability at idle.
To make a meaningful adjustment here, you need to consider factors like boost pressure or engine speed (or something similar) to determine when to activate the resistor.
From a practical standpoint, it doesn't matter which side the influence comes from; 2-3 is easier to manage.

Does this now mean that we can also try connecting it to pins 1 and 2?

Basically, yes, but I don't think it offers any advantages over 2/3.
