@ Randy:
A few pages back you asked me to get my full setups for my 2 systems to try and help me make my Gen2 combo feel like my Gen1 combo (Gen1 seems more responsive and much easier to make short run up gap jumps, though top speed down the straight seems the same). I finally got to the HotWire at the track with them both. Each is in a Tekno EB48 with an 18t pinion, using the same SMC 6500 4s pack.

These are the settings. The one difference that jumps out to me is the RPM for timing stuff. Both were set up by hitting the calc rpm button while connected to their respective t8 1900 motors and choosing the top rpm available so it would only be active at the top rpm range, but the numbers are very different.

Gen1 RX8 w/ T8 1900 running 223 software:
13v cutoff, bl-dl
no drag, 65% brake, no push, brake min 5
25 neutral width, no current limit, 40% reverse, throt min 0
C2, 5 timing, 28251-32034 rpm
linear curve (3)

Gen2 RX8 w/ T8 1900 running 238 software:
13.5v cutoff, bl-dl
no drag, 50% brake, no push, brake min 0
25 neutral width, no current limit, 35% reverse, throt min 0
C2, 5 timing, 18471-20016 rpm
