Neither speedo cogs with mod motors, 17.5t isn't really suited to sensorless.
My 8.5T EZrun in my XXX-4 has no problems keeping up with the other 4wd cars in my class. I am a bit slower down the straight, but everywhere else I'm golden. They are running anything from 5.5T's to 7.5T's. The 60amp ECS is good down to a 5.5t, so I don't think your going to have any problems.
