Today i went to replace the inverter to test if newer had more torque.
I removed the cables and inverter itself. I replaced my older inverter P/N 9410A081 with newer model P/N 9410A163 from 2020. After a short drive later this evening it really seems the takeoff is somewhat more powerful.
Megane is quite a bit heavier than Mazda, 1800kg vs 1200kg and 400kg more is showing no matter how i go at the throttle code. I will elaborate later...
