    how can i make bbs01 PAS respond quicker from standstill

    Ive gone back to using my bbs01 after a period of using bbshd. I love the lower powered bike ,but its dissapointing in one important feature. The bbshd is off the mark as soon as i start turning the cranks. The bbs01 however takes forever for the PAS to respond. I make sure its on say the T17...

If you set the 'keep current ' to say 50% .You will get 100% of the AMPS for the selected PAS when peddling at low cadence...
