Quick ecu Question ?

[90_240sxx]

hi i got an s14 sr20det and i still cant figure out y im running lean. I think i got the wrong ecu? When i was buying the motor i remember that the pics of the ecu had an N/A sticker on it but when i got the motor it came with a WC ecu . the car runs good but it just runs lean which it causes it to over heat and I just wanted to know if that would cause it to lean out, im just trying to eliminate some things before i buy them. Im still looking in to some other things, right know im downloading the manual book for the s14 so hopefully that will help me out. oh and im not dring the car its just sitting in my driveway so if any one can help THANKS.

The NA ECU is a late model (1997-1998) S14 ECU. WC is for earlier model (1993-1996) S14 SR's. The NA doesnt plug into a WC wiring harness, and vice versa. So the NA shouldnt fit, if it does let me know.
