FS#3 - Throttle angle limited when running speed density

Description

At full acceleration, the target throttle angle does not reach 100% and seems to have a ramping when using speed density.

Does not affect 2.5T users.

Finding the culprit

The target angle is based on the airflow requirement. When flooring the accelerator pedal, the ECU add an offset to the base target. It has been confirmed this offset is applied on speed density setups as well, which indicate the offset or the base throttle angle is lower than when using a MAF

The base throttle angle respects the torque and airflow model. The culprit is with the offset added at WOT. The 2.5T are not affected due to the high manifold pressure requests that max out this offset

Todo

  • Log variables from the offset function to determine where the offset is lowered
  • Implement a patch based on those results or a hard patch to max out the offset @ WOT (Similar to 2.5T)
