Difference between WC ecu's in red and black?

[devonkyle77]

i am looking to buy a wc ecu and i have found a few. the one that went bad on my car has a red sticker, although most the ones i see for sale have a black sticker. they all say they are for s14 sr20det, so should i be concerned about the difference in the color of sticker? any clarification would be greatly appreciated. thanks

Hey Devonkyle: did you end up going with a black WC? if so, did it work out for you.

i've also been hearing that it doesn't matter, but wanted to know if anyone else has tried it successfully.

by the way, what symptoms were you getting when your red WC crapped out on you?
