Hi gorp , Thanks for the tip to check the gude assembly . I'm just changing the chip to be safe becuase even though it is working it will only register lap times on one lane . Thanks Jim
It is NOT the chip.
It is the the lap counter unless your other cars count on the bad lane.
If they do not work on it, try cleaning the eye on that lane.
My first apb was dead on one lane so scaly replaced it.
Of course replacement counted but is bear to get both lanes of analog to run in 1 direction only.
Back to problem - if other cars count but yours will not, try cleaning car eye.
If dpr have no other solution but if soldered in, the eye may be up in body too high or to the side.
Oh forgot to ask first - You do have at least 1/2 straight before lap counter so car can pass headed straight and not traveling sideways out of a curve ?
If no, then fix your track layout.
