I spoke with Jake D and Kody Knudson a bit at the track on Saturday about the torque timing. I'm not sure anything got clearer.
I also tried a couple different settings. The track was green, so results are inconclusive.
#0 / 0* - My usual, felt like it usually does, i.e. a bit more bottom end than I'd like, but not too bad.
#5 / 25* - Felt noticeably smoother, but seemed to increase ESC / motor temp to higher levels than I'm used to. Touching the motor / ESC didn't burn me, but I didn't want my finger on it for more than about 1 second. I'd guess about 140-150*F.
#3 / 15* - Felt like more bottom end and mid than either of the other extremes.
I'm running an LRP x20 5.5 w/ 27.5* insert and stock rotor (12.5mm?) at 8.4 FDR with the 1.4 firmware. Initial drive is #1 / 3%. Boost Timing is #2-3 / 10-15*. Boost Angle & Activation is #3 / 0.6. Turbo is #1 / 5*.
Talking to Jake, he was wondering if what happens is that it's increasing motor timing to take away torque at the very bottom end. Then if you've got a setup without much timing, it will actually increase the low to mid range torque making it feel more aggressive. But if you put the setting even higher, especially with motor timing or aggressive boost, it'll over-time the motor at the low end, taking away the grunt, but making heat.
Maybe I should try another approach: If you've got a setup / gearing for the above motor for a 100'x48' carpet track, please share.
Our new layout is a lot of slow corners into straight chutes, with a big sweeper and a high speed chicane. So the low-end grunt isn't so bad as the previous layout that was very technical. But a bit more smoothness for the final corner into the sweeper would be good.
