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?
i have this problem with my proton 1.6 Sedan where the trunk has this cranking sound when the car is idling or when i am driving through a bumpy road....
