Hi

I recorded the boost pressure over speed during a normal drive:

Can an AFN driver provide this data for logging (e.g., 011 or 010)? (Ideally over a longer period, such as my graph showing 1.5 hours on the highway)

Oops, there I go again with blueberries:

Here's what I was planning:

The AFN doesn't actually arrive significantly earlier with the higher boost pressure?

hi,

frage: what do you mean by 'earlier'? I thought the 1Z and the AFN both had a maximum pressure of 1900 U/min. So, what's different about that??

Hi,

At 1900, it achieves the maximum torque, while the maximum boost pressure is significantly lower. You can clearly see this when you have a high load and low RPMs, because otherwise it would normally spin out of the range too quickly.

I didn't really pay close attention, but yesterday when accelerating from 60 mph in 5th gear (with 4 people, luggage, and going uphill) after passing an Autobahn construction site, I had 1 bar of boost at 1500 rpm.

Log is currently not possible, I need to find time to modify the power supply so that it grounds the notebook power supply.

Best regards,

Jan

So, bei 1500 U/min sollte der 'target LD' (oder 'target Luftdruck') nicht einmal 1 bar betragen...der 'target LD' von 1 bar sollte bei ca. 1900 U/min liegen...und das funktioniert.
