Hi everyone,
I came across the BMW M5 engine management system. It is kinda interesting how the ECU limits the maximum engine rev during cold start to 4000rpm only.
Anyway, I am looking for the possibility in using the ECU to limit the engine rpm during -30 C cold start.
My question is, at such a low temperature, how will the ECU know that the engine will be started at such a low temperature. Is it through the coolant water temperature sensor only, or there is other mean in knowing that the engine is about to be started at such a low temperature?
