Really Really stupid newb SR question

[MoNkEy_MaGiCx]

hi all,
ive been around the site for a while but i dont post much...since i dont know too much about all the tech stuff....anyways...i was reading through some mags laying around my rooma and i saw some cars that had a SR20 with a k/ph and some with a mph speedometer....is it becuase you can re-map the ecu to read mph? or is that guys speedometer messed up?...i really dont know any tech stuff about cars....please dont flame....

japan = kph
us = mph

whats all i can think of

Actually, if the car had heads up display (hud) you can switch it I believe on the Japanese model. I have it on my 240sx but you can't switch it to K/PH. You can rewire your original USDM gauge cluster into the SR harness also.

This was actually a very good newb question.

yep. you dont remap the ecu. its just a wiring issue.

[MoNkEy_MaGiCx]

o ok...so if i just keep the USDM wires and stuff then ittl read mph?

thanks for all the help

Its all in the gauge. They both read the same signal so its just a mater of plugging in the MPH gauge or the KPH Gauge. SCC did this on there project silvia, I think they had to trim some plastic to make it fit, no biggie.
