hello fellows, i wanna know with how many volts works the tachometer on the clusters, now i dont got a pcm for that, cuz im looking if we can retard the signal we can make the car rev higher!

 

well first off i wouldnt reccomend doing that.....the computer montiors the engine speed and alters the spark timing due to higher rpms......if you change it it might not rev very high at all...itll probably pop miss and backfire alot.

 

yeah i know that, but i wanna try, lol! but u know that? about the volts??

 

well take a volt meter and measure the voltage.....grey with a blue tracer if i remember correctly......then change the size of the wire...that should change the reading.......good luck
