turbo timer help Pls respon asap

im goin with the greddy cause my dad used to racve and told me greddy is the way to be.. i wish i had my dads brain... he knows alot.. i smell bonding
 
the difference between the type 1 jspec and the type 1 us spec (black) is the units of measure for the timers and measuring functions. the jspec is metric and the us spec is standard measurement. oh yeah, and the color the us spec is black and the jspec is silver.
 
uhh i think im gonna get the US spec (??? im not sure even what spec is at the shop, i just saw type one). id like the measurements in units i can understand...metric makes more sense, but ive grown up the american way :p :p

and yes, my left arm is gone. lol
 
i have the US SPEC TYPE 1 best s***. its compact & smaller than the greddy better functions. shift light tachometer speedometer lap time 1/4,1/8, 60ft, 0-60, voltmeter autotimer and lotta presets. they only come black and its a breeze to install. comes with wires and t splices. only need to solder the main harness.
