I'm running a Rapidbike tuner with the add on RB shift assist/quick shift module. My shifting activation is becoming inconsistent as to when it decides to interrupt fueling and allow for the shift. I see some of you guys with factory QS replace just the load cell with an aftermarket load cell with good results. Is the cell on the RB able to be replaced with a different one or do I have to buy a replacement cell from RB? If they are universal, which cell would you recommend as the replacement ?
