What I have found on our small carpet track was that with a 17.5 (SP V3) low FDRs overheat the motor. This was tested with motor timing set to 0 (which isn't saying much, because as we have seen BL motor timing is not consistently defined across motor brands) no turbo, boost at 45, wide boost window starting at low RPMs (2000ish-17000ish), linear throttle profile (3/4) and no drag brake.
Low FDR seemed to work better with v200 as far as overheating problems are concerned. Motor was Tekin 17.5, timing as per factory setting (not sure what that is), turbo at .7 delay, boost all the way up, profile 3, no drag brake (I am not a fan of drag brake because we have a tight technical section where I would rather let the car flow freely than brake).
There is still some testing to happen as soon as the track opens again but this is an interesting difference between the two software versions.
