Good day.

The injectors in my Golf 4 1.9 TDI with the AGR engine have now reached 330,000 km, and I would like to replace them.

In light of this, I would like to switch to a larger size right away.

I was thinking of using "simple" 0.216-inch nozzles. After consulting with a relatively well-known software specialist, he would now like to have various performance characteristics for them.

Specifically, it concerns the "flow map" or "control duration map." Otherwise, we would have to run the tests for a relatively long time, and that wouldn't really be worth it.

"Does anyone have these identification codes, or does anyone know where I can find them? Unfortunately, my Google search didn't yield any results."

Sure, I'd be happy to help!

Thank you very much.
Best regards,

= Limited Specialization }

For an engine with 330,000 kilometers (approximately 205,000 miles) on the odometer, I would...
- Only replace nozzles if they are defective.
- Avoid any "performance enhancements." Unless the animal is going to be slaughtered anyway.

Baby, your fuel pump is probably already broken. Let's not even talk about the turbocharger; it doesn't provide enough air for the injectors anyway.

And there's definitely no support available for "Ctrl+C, Ctrl+V" tuners.

Hm...

To be honest, the tuner now seems like a reputable company.
I can send you a private message to let you know who it is.


Denke aber das hier dann eh nichts mehr rumkommt. Too bad.

If someone is a specialist, as you claim, they should possess such qualities.

Sure, here's the translation:

"Just a quick question for clarification on my part:"

Are these parameters not different for each nozzle set?
Or are the performance metrics I'm asking about always the same, regardless of whether I'm using tires with a size of 0.216 or the original equipment (OEM) tires?

Does ALH always use these specific metrics?

No reputable tuner would work on a car with 330,000 km and then ask for help to properly utilize the injectors.

I don't even want to know who it is.
