If i am running the BF oil temp and presure meter with a controller but i don't know what controller. Can this tacho work with it?
Another thing is how accurate is this tacho? I using the USA autometer and i find it not accurate as it always varies with the car's rev meter. the car meter show 8krpm but autometer show 8.2krpm?
does anyone know how to set the frequency into a new remote of car alarm? i just changed a new battery in the remote but the memory is lost, anyone how to program it back? i'm not sure what brand is my alarm, but...
