s14 SR ecu question

[SidewayZ-s14]

Hey guys. Long story short. I picked up an s14 WC (black) ECU for my s14 SR20DET. Will this ECU work? I've heard that the s14 black WC is for SR20 NA.

This ECU is chipped with NISTUNE so that's why i purchased it.
The one that is currently running in my car is a red WC.

Thanks for all the help!

the wc is for sr20det s14 or s15 and NA is also for sr20det ...they both pretty much the same.......i used to run the wc for my s15 and it work fine...until i went with pfc

Oh i gotcha!
Well i put it in and it works but it sorta runs like crap lol!

The guy i purchased it from said he put the stock bin file back on their but i doubt he did. His setup had 555cc injectors and whatnot so im sure that bin file is still burned to it.

The ECU thinking i had 555cc injectors and not 370 would make it idle low? Thanks for the help!
