Past few days the cars not boosting right! its a seat leon 1.8T sports - P torque remap as well :D
i measured the blocks 115, actual vs requested.

when you put your foot down the car dosnt seem to pull till it hits 3500rpm.

so the actual boost slowy shoots up to the same as requested.

on the boost gauge it shoots up to 1bar boost then stays around 0.7boost.

just replaced the n75 around 3/4 months ago.

Try 1st thing 2morow. abit late.
quick question about the post lambda sensor, does it effect the air/fuel ratio or boosting? as it keeps coming up as internal resistance too high.
Cheers

Here goes guys final figured out how to do it.
The car is seat leon 1.8 Sport with P Torque remap.

Cheers

2nd gear runs are a bit pointless, not enough time or load.

I can't see what you mean about actual not meeting requested. The logs prove otherwise. Boost looks fine. It's running a tad leaner than requested though.

Brummy
Just that the car feel slugish at some times, asume it not boosting right due to other factors.,

what colum shows if its running rich? is the V colum?

Well what kind of temperature would be reasonable?

Cheers DPJ for all your help!

I appreciate you've got more pressing issues at the moment (clutch pedal)

No, the car looks to be boosting fine from the logs. The heat issue is because you 've just got a SMIC and the car is getting heat soaked after a few power runs. The first of the Lambda columns is actual fueling, the second requested. I'd have a word with P torque about it, perhaps.
