b20vtec swap...throwing code 45
code description:
45
System Too Lean or Too Rich malfunction in the fuel monitoring systems
I drove the car for over 300 miles home and then going down the last street to my house CEL comes on. I reset it for the heck of it to see if it came back, and sure enough...60 miles later or so it did.
I recently had a b20b block bolted up to my b16a2 head for a CRVTEC setup done by a shop. They said the engine is running a little lean up top (nothing bad, except performance hit) and to replace the b20 injectors with my stock b16 injectors when i get home. Aren't they the same size?
Any info on what it could be or what i should do would be appreciated!
Thanks,
mike

maybe youre runnin leaner due to more displacement.. i say you get a adjustable fuel pressure regualtor first.. that might solve your problem there.

I am using some GSR injectors, but they are 240 just like the rest. I do have a fuel pressure regulator set at 50psi with the vacuum hose connected.

I'd seriously consider at least 310 cc injectors. If you think running lean at 8000rpm is ok, just a performance loss, research again.
Look into your O2 sensor as well...
