/confusedI can assure you the S14 speedo with RB25 VSS reads correctly. The KA VSS shouldn't even fit in the RB25 transmission.another VSS thread here zerothread?id=167001Bluefire wrote:s14 rb25 speedo does not read correctly either. I've done two and both read slow just like the s13. Speed sensor is also the same for s13/s14/ka/sr... except different plug. So as far as I can see the only speed sensor that will work in the RB25 transmission is the RB25 speed sensor.
Also I tried the jdm s13 speedometer in my ka cluster and it freakin read just as slow. I was hoping it might be a little closer, but no dice. Also a weird thing I noticed with the pot on both usdm and jdm s13 tachs. It jumps from ohms to kilo ohms with a slight adjusment, almost seems exponential, unlike s14 tachs which seem more linear. I know if I can get just one more day to touch my car I can get this all figured out.

Re: (eh?)
Well pertaining to the two s14 rb25's i've done, both have read slow, so take it as you will... But maybe there might be something here. Both the RB25's were sII's, was yours a sI by any chance?eh? wrote:/confusedI can assure you the S14 speedo with RB25 VSS reads correctly.

Re: (Bluefire)
Finally got my cluster back from LS AUTO on friday,.......their websites says turnaround time is a week, well, Mine was 3days short of a month!! But it works fantastic. Tell them you need your speedo calibrated as well, they should be a able to take care of it. just be prepared to not have a cluster for about a month.Be VERY clear of what your car is, what cluster your car has and the new drivetrain that is in the vehicle, also let them know what your problem is.

zenki s14 w/auto cluster...RB20det. I use the Ka speed sensor, so it is pretty accurate.
