Is tuning possible by replacing OEM messages?

Hello,

Is it possible to perform an engine tuning on a Fabia II 1.2 TSI with Simos 10.1, involving a MSG (Engine Control Unit) replacement and WFS (Workshop Information System) adjustment, at a regular Skoda workshop?

Background:
A local dealer still has a few models with the 86 horsepower engine (engine code CBZA) in stock, but we would prefer the 105 horsepower version (engine code CBZB).
The only relevant differences are in the MSG and the VA brakes (15" instead of 14"). Swapping both of those parts wouldn't be a major undertaking, and it would result in an OEM engine with 105 horsepower.
The parts catalog does not list any engine-dependent differences for the AI model.

The question is whether, during the WFS (Wing Flap System) adjustment, the FIN (Flight Instrument Network) is also evaluated, and whether this could lead to a situation where the installation of an MSG (Maintenance Steering Group) of the wrong performance level is blocked...?


Okay:
Why not chip tuning?
My answer: Because OEM software generally has the best quality.
And even if a tuner says they're copying our original 105 horsepower software into the engine control unit (ECU), how can I verify that without a diagnostic tool and the original software data?
My file collection has so far consisted almost exclusively of TDIs.

Hi,

In the Octavia forum, there was a similar discussion about the question of CFHF vs. CFHC, and I believe there's also a thread about it here.

Okay, I'm ready. Please provide the German text you want me to translate.

I think what was said there applies completely to your situation as well, especially regarding the safety features.

In addition to that, there are the exorbitant costs associated with the new MSG.

Looking for a reliable tuner that does exactly that?

In any case, the warranty on a new car would definitely be voided.

Best regards,

Jan.

Thank you for your input.
The matter is now settled, as we have ordered a Rapid Spaceback with the "top" engine option: a 1.4 TSI with 122 horsepower and a DSG transmission.

Hi,

Congratulations!

Best regards,

Jan.

Thank you, but it will still take about half a year before it becomes a reality. "We'll continue using the non-air-conditioned Polo over the winter, and the Rapid is scheduled for delivery in March."

That was a justified request from my better half. And, as is well known, one should not anger them .

Hi Ulf,

CAXA and DSG work very well together.

Keep an eye on the wastegate in the CAXA.
The Mitsubishi Turbo has a tendency to seize the wastegate. However, there's already a repair kit available that includes a new exhaust housing. This is detachable from the harness.
And you can clearly see the water pump even with the hood open.

Currently, there is a recall for the 7G dry dual-clutch transmission. The change is from synthetic oil to mineral oil because the synthetic oil... Contacts can be eroded.

If you have any questions, feel free to ask - I'm not that far away .

Greetings.

Thanks for the tip.
However, newer CAX models don't seem to do that (as often?), at least that's my impression from browsing several forums that discuss these engines.
For example, within the Skoda community, people discuss all sorts of problems related to the Rapid, but issues with the turbocharger on the CAXA engine haven't been a topic of discussion so far.

Does this affect the filling of the transmission or the mechatronics?
"Kontakte anfressen" sounds more like the latter to me...?

You still have about 5 months to increase the distance - then we should get the Rapid

Oops, you're right, that's not the same soup.

Since the lower drain plug is marked and the volume is supposed to be around 1.7 liters, we're talking about the actual transmission oil.

Thank you!

While I could cling to the hope that the DSG (dual-clutch transmission) of our newly ordered car will be properly filled with fluid... there's a chance that the transmissions could be lying somewhere in a storage yard and installed with the problematic oil.
Therefore, I will contact our distributor at the beginning of 2015 to find out what information he can gather on the matter.
