Hello,

brauche mal für einen Versuch den spritzbeginn bei max. Speed.
(between 4000 and 4500) of an AFN and 1Z that are chipped.

Only the maximum injection start time is needed. Provide a single value with the corresponding unit.
Speed is sufficient.
The maximum power output would be helpful for my experiment.

Since I don't want to start an unnecessary discussion here, could you please tell me...
Please send the information to me via private message.


Thank you.

Hi,
What are you planning to do, or what is the purpose of this?
I can provide you with the values of the serial software, which offer at least some level of...
It has a certain level of validity, but when it comes to tuning datasets, it always depends on what the...
'Whether the respective tuners are correctly configured and whether they have found all the relevant parameter maps.'
In addition to that, there are also the mechanical limitations of the injection adjustment...

If you have datasets, I'd be happy to extract the key information for you.

Best regards,
Rudi

I just wanted to collect some data so I could have a better understanding.
by how much I can move the start of the injection forward.
Without going overboard.

I wanted to do this in conjunction with a box to see how it works.
"how far I can go. Since the box also controls the boost pressure..."
The only thing that can be adjusted is the start of the injection.
must.

You can only meaningfully change the start date in the dataset. However, if you're already modifying the dataset...
touches, which is then what the silly bird with the box icon_question.gif icon_question.gif icon_question.gif does.

The start of injection, labeled 'Max' (which is not the intended operating map), occurs at 1Z, and the air-fuel mixture reaches the stoichiometric point (AFN) at approximately 17° before top dead center (BTDC).

Best regards,
Rudi
