Golf III: 90 TDI auf 110 PS TDI "umbauen" | Posts 16+

Hi,

In classic chip tuning (for engines like the 1Z or AFN), the engine control unit (ECU) must first be removed, and the EEPROMs need to be accessed.
'are desoldered, and the base is cleaned (if it hasn't already been cleaned).'
and then the modified EPROMs.
The discerning tuner will not give a damn about the data status.
he was in. He will retrieve the corresponding dataset for this vehicle from his files.
Get it, install it, and that's it.

But to answer your question:
Moderate tuning chips (possibly with a certification) do not necessarily need to be installed.
The calibration stand needs to be adjusted (while the tuner is, of course, connected to the adjustment process).
(which is also a worthwhile investment). I believe individual adjustments to the vehicle are only truly worthwhile at that point.
meaning, if there are significant performance improvements or improvements in performance.
Connection with hardware modifications (e.g., larger injectors, larger turbocharger; applicable to gasoline engines).
(modifications such as a high-performance camshaft, etc.) can be made.
However, there are very few ready-made expert reports available for such modifications.

Best regards, Rudi.

'Now, I'd like to share my opinion on the topic of chip tuning. At first, I was also interested in everything you can get out of an engine. However, I believe that the engine manufacturer (in this case, VAG) knows a lot more about the engines than anyone at TDIs ever will. Why don't they equip the 1Z engine with 110 horsepower from the start? For my part, I trust VW, believing they have capable programmers. If I want more power, I'll simply buy a more powerful car from the beginning and avoid trying to squeeze more performance out of a weaker engine (at the expense of the turbocharger and the durability of the engine block). This kind of TDI tuning reminds me of overclocking a processor; it pushes the safety margins and durability to the limit. A processor might run for 1-2 years if it's overclocked, while an engine is supposed to last around 10-15 years.'

Hi WarLord,

also, it's a certain attitude, and definitely not the most unreasonable .

VW and Audi application engineers usually know exactly what they are doing.
and they also do their job really well.

I wouldn't get a 1Z engine, even if it was somehow tuned to produce 110 horsepower.
release it for public use, if I had to anticipate that someone might...
'Driving from Flensburg to Munich at full speed, assuming traffic conditions allow.'

My 1Z usually has (with the boost pressure set to the standard setting) just under 110 horsepower.
That's not a particularly generous amount of power (with reasonable settings) for a 10-cent power box.
and rather low for a chip tuning upgrade (playful thought: 125 hp also works, and 96 kW is the power output).
Chasing Passats can definitely be fun ; (Playfulness OFF).
Despite this, the engine (in my case) operates for more than 95% of its runtime with fuel injection amounts that correspond to the standard operating parameters.

It really depends on how you use the vehicle. If I always drive to the border,
A more powerful engine might be a better option. Otherwise, tuning can definitely be worthwhile.

Best regards, Rudi.
