Hello,
Maybe a specific question for anyone who may know here. a.k.a. Mihnea?
Is the overboost function of an AAN motor, an additional table in the ecu that doesn't exist in the 3B? Or are these just different values in the same tables?
Dahlback offers two mods for stock AAN motors, one that gives 269hp/304ftlbs and another that uses a 3.0 bar PT 269hp/328ftlbs.
To me it seems that the higher torque but same HP indicate higher boost pressure at less-than-redline rpm levels, tapering off as rpm increases to save the turbo.
Whether that is translatable to the 3B is the question.
Thanks,
Ken
