Full-load trucks AFN 1500-1900/min, only with hot PÖL

Hello!

I have a 'beauty error' during full-load acceleration between 1500 and 1900/min.
The shaking only occurs when I fully accelerate with PÖL at low engine speeds.
Here, the fuel has a temperature of 75-80°C in the ESP. While the full performance is present, it stutters significantly several times in this area.
He pulls significantly stronger than with standard fuel and easily reaches the top speed.

The nozzles are still 4000 km young and have a .205 series diameter.

I am using freshly pressed canola oil with 15% 'AngstDiesel' mixed in.

If I use diesel again to verschandeln the system and create the same situation, it will verschandeln softly and evenly over the entire area.
Therefore, I'll exclude the well-known 'counting problem' and the 'needle-picking' issue.

My question: Can full-load trucking be caused by excessive fuel injection?
'Because in PÖL mode, the displayed fuel consumption is lower than with diesel, I explain this by the fact that due to the higher viscosity, the lower amount of leakage, and the increased volume due to the high fuel temperature, more fuel is sprayed through the nozzles than is indicated.'
Since the torque limit has also been increased by approximately 10%, the amount with PÖL might just be reaching the threshold, while not exceeding it with diesel?

Please provide feedback on my assumptions and possible solutions (e.g., adjusting the fuel injection amount?).

Hello!

Although no one could help me further, reducing the injection amount by 2 mg per stroke through adaptation now allows him to run smoothly even with PÖL.

Maybe someone else is also experiencing issues with high-viscosity fuel
