As the title states. Finally got my car running again but I have a couple different set of injectors lying around. So could somone please inform me what color the 480cc injectors from the SR are and/or what color the stock 270cc injectors are? Thanks a ton!

 

stock sr 370cc are purple

 

Thanks, I was looking for the 480 color though, the s15 ones. I searched ebay and they all came up as RED, however, mine that are SUPPOSED to be 480's are a pale pink color. I dont believe they are 480's though cause at idle, the wideband reads stoich at 0% correction. However under part throttle condition like at 2000rpm and 10% throttle the correction is only -11% to get a/f ~ 13ish. I guess I could do the math, but Im not sure if my wideband is being gay or what. I dont think it is cause at idle if i set the correction to -42% it idles like ass and reads 19 a/f on the wideband. Im gonna be pissed if these aren't 480's

 

480's are redish pinkish (yes that's Crayola color as well). That's compared to 270's which are deep red, and Nismo 740's which are bright red.

 

redish pinkish. OK, so I assume these are the correct injectors even though all the ebay ones are RED. Anywho, how does one explain STOICH at 0% correction on the SAFC at idle? It is definately wired right and all that jazz. The shit is wierding me out. HAHA

 

It's called closed loop fueling at idle. The ECU adjusts the fuel until it sees stoich on the O2.
