Sounds like the translogic stuff can't deal with counting 40 odd clicks per wheel rev. software not up to the job. I wire up dash mounted dataloggers to the front wheel. Easier wiring, run the wire down the speedo cable/brake line. Little bracket off the axle pinch bolts to pick up the front disc bolts.
Okay I'll conceed you cant see what speed your wheeliing at
