I have been looking around for an ECU map/tune for the F01/F02 740.
Although it is the N54 engine its is slightly more powerful than the typical N54 in the 335, so most tuners don’t have the 740 listed along the cars with the N54 engine that they tune.
Not sure if the difference is only software or hardware as well.
Here is what I have found so far (Updated):
