So i got my kit the other night and i have the whole thing done but i just have one problem. My kit never came with a resistor for the R57 spot on the board. If i do need it can some on tell me what it is so i can run to radio shack and grab one.

Thanks
mike

 

R57 is a spot for a pullup resistor. Using it depends on what type of input circuit you plan to build and is optional. For MS3 on a standard miata, I set up CKP input through the VR circuit and populate R57 with a .5-1k ohm resistor (the exact value isn't terribly important within reason).

Additional info is found in the manual:
