That A/f is way off!


Yup, I had the same exact problem with my ITR motor in my EG. It couldnt keep up in the high RPM's. Probably explains why its soooo lean when in VTEC.

I wouldnt be going over 3000 RPM's until this is worked out. :eh: It'd be a shame to pop that motor.

Compare your stock motor to the B16b and you tell me. :wink:

- Mon Jul 23, 2007 5:58 pm #16437 i would agree with mike a stock civic pump is small and a stock motor doesnt need much fuel throw a itr motor in there you should most def change the pump and get at least a simple tune so it dont blow. at least if it were rich it would be safer then being lean

- Mon Jul 23, 2007 6:08 pm #16440 I'm surprised the tuner didn't catch it running so lean the first time :shock:

either way, I'd get it tuned after. It's like insurance - $150-200 bucks is worth the piece of mind that you're not ruining your motor :thumb:

You still have the issue of running bad when the weather is hot right? A tune could solve that too. Then if it starts running worse when the weather cools off, save that tune and have it tuned again for the colder weather.
