well, the mph was working fine when i had my stock cx cluster, but when i swapped it out for an Si cluster, the mph seems to be 10 mph off. it would be 0, but when i hit about 20mph, the cluster reads 30 mph.

also, when i come to a complete stop, the mph needle is a bit laggy and even though i am stopped, it still continues to fall.

o yeah, and when i turn the ignition on, the mph jumps to about 1 mph even though im not moving

please help

 

Did u check all your connections on your cluster? Just go back and check them first....then check your VSS for loose or bad connection....then check the VSS for the proper Ohms (I think its Ohms) of resistance and see if its outside of its service limits...I am not sure of the specs on the Vehicle Speed Sensor but that is something i would check. From personal experience I would check on all the grounds. For credibility sake I am a diesel mechanic in the army....I troubleshoot bullshit all day long.

 

thanks.. i checked and cleaned all the connectors to the cluster. any other ideas.. do i need to open my cluster up and check some thing

 

the calibration for the speedo and tach is different for the si cluster and the cx, dx, ex cluster. so it is going to be off.

No, there shouldn't be a calibration problem between models. 20 MPH in a CX is going to read 20 MPH on the Si speedo. Maybe the previous owner took off the speedo needle to turn the odometer and didn't calibrate it.

 

I put an USDM 99 Si cluster in my 98 EX 2 weeks ago and it read fine.

how do you calibrate it?

 

Yeah, I'm guessing the previous owner of the Si cluster had the needle off. And once that happens, it's hard to make it read properly afterwards.

 

I think there are shops that can calibrate speedometers. I am unsure what they are called.

 

u could swap your old speedometer into the si cluster. The faces won't match but at least everything will read correctly.

 

haha thanks.. man this is wack. any suggestions?

anyone with a link of how to calibrate? i seen one before now i cant find it

 

calibration...

35 bucks most shops

 

any links for calibration thread

 

maybe chp or the local pd can do it...?
