4.4 rear end and speedometer calibration 95 240sx

[karmakaze]

i have a 95 240sx and a s13 VLSD/axles with the 4.4 ring gear that i am about to install.

this will set my speedometer off by about 6.0% so, should i go about recalibrating my speedometer? and how do i go about doing that? or am i better off with an Apexi Rev/Speed meter?

i know where and how to take the voltage reading, but i can not find much on how to do a calibration.

is there a pot on the back of the gauge cluster?

you got it. It's on the back of the speedo.

you got it. It's on the back of the speedo.

what is the range? 1 to 5 volts? and is that scaled 0-120mph?

so do i just use a voltage generator and turn the pot until the speed reads 6% higher?
