I dont expect to make any more overall power than BM3 (they have been doing it a long time) I just want it in a different way. Lower torque low down which should be easier on the rods and keep thing cooler then keep more power top end which will be harder on the rods  .
Then when I mod the car further I can always tweak the map over and over.
I hear they are both very good. Not looked into it as I was never going to use anything other than OTS and my own |
The way the S58 works from factory is with a lower torque curve than previous S55 or even S63T4 (F90/F92).
The OTS maps are also following this curve
I've been on OTS for almost a year now and the powerband is perfect, it's exactly how it should be linear. I mostly run the E30 maps have you tried?
OP, I will be gladly to answer any questions for BM3 related too.
