Can the diagnostic tool also be used for the 10-cent tuning?

I have read the report on the '10 Cent Tuning' method. If I understand correctly, it achieves a higher fuel injection volume by manipulating a measured value. Can I also achieve a higher injection volume by adjusting channel 1 downwards?
If you then shift the injection timing by 1-2 degrees earlier, you should be quite close to what's known as the '10-cent tuning.'

Or am I making a mistake in my thinking?

I think that while it's possible to adjust the injection timing (like with a resistor-capacitor circuit using a Hall sensor, which is extremely simple and cheap), it doesn't create real extra power. It might improve throttle response, and it could reduce knocking. You really have to get close to the flow meter; otherwise, it won't work.
(I also have a cheap tuning chip for sale at half the price!)

Hello Joe,

Unfortunately, adjusting the fuel injection量 only results in homeopathic increases in performance .
Otherwise, your line of reasoning is correct.

Best regards, Rainer.

Hi Joe,

Channel 1, when adapted downwards , reduces (according to my knowledge) the (full load) injection amount.

One should not be misled by the fact that the displayed idle speed increases; this is related to the idle speed control system.

Rainer has already said the right things about the adjustment range of channel 1 - it seems to me that this is more about a way to reduce judder (which can also be achieved by adjusting the position of the control panel).

Advancing the injection start is generally correct when the injection amount is significantly increased, but my current attempts using VAGCOM to advance it by 1 and 2 degrees have so far yielded nothing significant .
(It seems to me that placing the resistor and capacitor in parallel with the NBF would create a more harmonious overall configuration.)

Hello Ulf,

I need to double-check if that's the case with VE motors as well. This is certainly not the case with PD engines.
However, it should be clear that adaptation channels cannot be effectively tuned (in a meaningful sense). It is, rather, a way to adjust the injection system to account for dimensional tolerances.
