On this car the green and red indicator lights no longer match the real revs - the lights are quite a bit ahead of the engine revs and indicate the need to change up when it is not he case.
The one you see on external views, which is custom to each car. It is fine with the standard basic info one you can toggle betwee.
The coloured lights are shift lights to indicate the optimum point to change gear, they're not a count down to the rev limiter.
Interesting to know that the BMW actually needs early shifts (i never looked at the power curve in the setup). But on the other hand there is still the problem, that now the rev lights on my wheel don't match up anymore with this car.
The production engine stats seem to be 7600rpm rev limit, 5500rpm-7300rpm peak power, are those the figures represented in the game?
No, the power profile is modified for Balance of Performance. The real GT4 makes use of a USB sticks to set boost pressure, rev limit, modify the torque curve and more. BOP bulletins pre-race specify which USB stick must be used for said event.
