a little more gas...

diagram is here

Outdoor temperature according to climatronic: 25 °

Note on the side: the seconds are incorrect... the duration is only 70 seconds long... needs to be adjusted next time icon_smile.gif

Hi
IMO, it doesn't seem definitively "wrong". OK, the LL temperature is still 5°C above the outside temperature, even after recalibration, but this could be due to errors in both sensors.

I also suspect that your LLK is not working properly: either it is clogged (externally) or it is not being properly supplied with power.

Hey guys... there's something to do...

I recently reactivated an old thread and am posting new data about my problem child...

http://www.8ung.at/blackmagic/blackmagic.zip

are three datasets... Excel spreadsheets, where the 3rd page of the spreadsheets contains the calculated and finished diagrams...

I have a problem: my speedometer shows 195 km/h, but the document states 206 km/h...

the ulf test takes 6.44 sec, I think it's too short if I'm not mistaken...

on the roll, it delivers 110.3 kW and 387 Nm (resulting in a vmax of 214.5)

So, what's going wrong there?

so, was ist da falsch?


Did I miss some information about the Tunig chip somewhere?

or is the test stand team responsible for the role?

At least the LL-temp is now within the normal range...

See you, Gremlin

no tuning chip... nada, nothing...

is still standard... the whole problem started because I wanted a tuning chip... but the tuner said that the car wasn't running at 100% and that a chip might not be the best solution until all the problems were fixed.

then I got into the role and he achieved a fantastic result... I don't understand...

but in all the manual tests, he's not doing so well

if you look at the diagrams, you need to add the following...

I've always tried to shift up from 2nd or 3rd gear, using full throttle, all the way to 5th gear to reach the maximum speed.

Therefore, the peak RPMs are usually around 3000-4000. However, you can see that it's just barely reaching 3500 in 5th gear... (Although it has 6 gears, it doesn't have enough power to reach the top speed in 6th gear, and it takes even longer to do so).

Can someone calculate how much faster it actually is... Unfortunately, I don't have the gear ratio handy right now... The highest RPM in 5th gear was 3822 rpms.

Winter tires 195/55 R15.

hmm...
I'm wondering why the moment injection limiter allows less injection when I increase the engine speed from 3000 RPM in 5th gear to 4000 RPM... I thought that the moment would also decrease at higher engine speeds...
