Hello Richard,

Blocks 3 and 4 are looking pretty good now.
In Block 8, Field 4, the injection amount of >41mg/H is still not being achieved. This is due to the insufficient air mass in Block 10, Field 1. It is also very clear here that even when exceeding the maximum boost pressure of 2300, the required air mass is not being reached.
Is the intercooler piping really airtight?
Please also disable the EGR valve and perform another test run under full load.
Are you absolutely sure that the LLM is working correctly?

Hello Michael,
The measurement blocks in my previous post were operating without AGR (Abgasrückführung).
I tested my LMM by installing it in a different car.
'I had already installed it, and the LM values were okay.'
Unfortunately, I can't check the entire length of the intake air path because, after the turbocharger, the pipe disappears under the engine and only reappears at the front.
Is the rubber hose already damaged, or is there another way to check the line?

Sure, here is the translation of the text from German to English:

'Hello'

Richard.

Hello Richard,

Okay, please perform the measurement run with the EGR system activated.

Hello Michael,
I may have expressed myself unclearly.
The postings from 9:09 and 12:47 are measurable values without AGR.
that from 14:23, with agr.

Richard.
