dude, if u open up d tacho, there is a switch u can select usually 3,4,6,8 or something like that. if ur car is a kancil, flick it to 3, if wira or any 4 cylinder car, flick to four, if V6 cars, flick to 6 if u have a v8 engine what the heck are u using an autogauge meter for?! hehe no la flick to 8 lor
there are cases were some ppl buy tacho for bikes, if its for kapchai, it will be wrong. my car is a proton 1.3 injection and driving at 80 it shows 8k rmp last time.. dats motor wan. doesnt work at all unless u hook it up to a bike.
