I have a 93 CX and I swapped an EX/Si cluster in it and the tach was way off, like over 25%. I heard this was a common problem...so i took that cluster out and put the stock one back in and got a 2.5" autometer tach. Now I dont like the look of it because im going for a sleeper look. My question is: is the SiR cluster tach known to be accurate or do people have the same problem as with the EX/Si clusters?

how do you know that it was 25% off... that is a lot or RPM to be off!

Stock tachs are inaccurate up to like 500 rpms. You will have the same problem depending on which one you get. One tach may be more accurate than another.

I dont even look at my stock tach anymore, Full Throttle Launch set to 3,500 (crap *** tires) cel shift light at 6,800 (SOHC ZC Vtec no high rpm power) and let the computer tell me where i am at.

Unless i get really noisey then i pull out my laptop and hook up crome pro

i think i will leave the autometer
