Hello everyone
I'm trying to tune my M2 N55, but I have a throttle closure from around 2600 rpm, yet the boost and pre-boost seem to match, right? Where do I have a torque limiter table? Because I feel like I'm limited to 500nm on the monitoring screen.
thanks

Any ideas?

If by monitoring screen you mean the sport display on the car, I'm pretty sure its artificial but I could be wrong. If you are using tunerpro, make sure your transmission torque tables are set to a high value (like 900), and look at the load to torque tables to see if you have them set too low. In my table I kept it stock except for the last two rows that I rescaled to 180 and 220 load with higher values and I'm able to push 27psi.

Hello, thanks for your reply.
Yes, I did raise the torque safety, I set it to 800 nm for the moment, because I'm aiming for 1.5 bars / 22 psi. I also played with the KF_RFMAXATL_KR table, but it didn't give good results. However, with the KF_RFMAXHDP table, I can set my target pressure as I want. For the screen, I found the solution; I had to change the values in the file in KF_EDA_ANZ_SPORT_MDK_IST. Now, full E85, I'm limited by the injectors, I'm going to change them to S63 eur5 injectors.
