hey guys, i just installed tachometer. i connected to ecu pin62 yel/red. it is working but it read only half of rpm... when 3000rpm tacho reads only 15000rpm. i followed instuction from autometer. i cut the brown wire for 6cylinder. and i tried other loop too. but still same. need help anyody...

 

Pin 62 may not work for that kind of tach. What cylinder settings do you have? Does it have an option for ONE cylinder?

 

no instruction has for 8,6,4cylnder... any idea. shoud i connect to coil. i found some information from other forum. it says connect to any ignition coil wires but not black or white/blue. but i have no idea where located ignition coils are...

 

i found ignition coils. i connected but still rpm doesnt match. no idea...........
