I've remaped 3 petrol manual bmw' so far each one the rpm was raised not by me asking its part of the map. If you put the same map on an auto the ecu on the gearbox will limit the rpm due to the torque converter/engine spped/actaul road speed. Which is why there different to test on a dyno to a manual using the best 1;1 ratio gear normally 4th gear. Go and speak to Jason then at BW chiptune ask about the aggressive remaps he sells. Even when i had a 3.0 Z4 with M54 engine we just copied the E46 ZHP fiile which had different max rpm. Have you remaped petrol cars before or not?
