Hey guys, just wondering if the stock Honda RPM gauges are accurate. For example if I wanted to put an EX/SI gauge cluster in a DX because I dont find the Monster 5" tach too attractive...but someone told me that the stock RPM gauges weren't that accurate at all. I think the EX/SI cluster with the RPM shift light seems good, but how accurate is the EX/SI RPM gauge?

Thanks.

 

 

accurate enough. not all cars are built the same that's all i can say. on one car it may read perfectly while on another it maybe off. mine reads super good!! i don't dig the Moster tach thingy. i think it's just a way to attrack thieves and such.

 

well i know that at 8000 on my tach, my VAC reads 7600. (similarly at 4200 on the tach the VAFC readst 4050)

 

the stock tach can be off
mine is off by about 200rpm.

 

My JDM tach is out slightly too, when idling the needle is at 900-1000rpm but my vtec controller digital tach reads 650-750rpm so its out by approx 200-250rpm. We swapped my controller in to my friends UKDM EG VTi (B16A) and his was reading out by 2-300rpm too.
