What do you think of the following instructions? They probably come from a 'pro' icon_question.gif mechanic. Please don't criticize me if this has already been discussed. icon_smile.gif

TDI Tuning with VAG-COM.

I found a way, thanks to my colleagues, to...
to give a TDI a little more power without any additional modifications.

noticeable in the torque.
Okay, enough talking, here's the instructions:
1. Have the error code read.
2. If there are any errors in the system, have them resolved beforehand.
3. If a tuning module is installed, it must be removed beforehand.

It could also be directly from the factory. VW has adjusted the value to be in the middle range.

4. Now, here's the tuning scheme:

It is very important to save the old values beforehand.

Now, the time has come. Your TDI now has a bit more power.

Try using the search function. We've discussed this before, and we didn't think it was very good.

edit: it could almost be an instruction manual from this auction platform, oh, what's its name again...? icon_biggrin.gif

Hello.

Although Jörg is right, here's my personal comment:

If I were to apply this to my tractor, the most noticeable results would be an increased tendency to jerk in the lower load range, and approximately 40 rpm more idle speed (as seen on channel 2).


Under full load, approximately 0.4 mg more fuel may be injected per cycle. This represents a significant percentage, around 1%, of the maximum fuel quantity of 40 mg, resulting in a nominal increase of approximately 111 horsepower instead of 110.
CRAZY icon_twisted.gif icon_twisted.gif

The author likely fully revved the engine during subsequent test drives and/or deflated the tires to such an extent that they had a smaller rolling circumference - which, of course, makes the engine appear to produce more power due to the shorter gear ratio icon_lol.gif.

Why did the specialist overlook the start of the spray = channel 4 icon_eek.gif icon_question.gif?

I'm not entirely clear on how a higher idle speed is supposed to deliver more power... icon_twisted.gif unless you're confusing a potentially slightly smaller turbo lag with extra horsepower.
