dood the idle is perfect from what i saw... it went to 13:1 AFR for like 1 second thats not enought to hurt it... and if you put bigger cams and its not tuned for it, it would actually run leaner not richer. im a tuner. i tune sr20's all day

Also, not tuning with anything. I have a mines tuned ecu for my setup minus my cams, bc 264's. I don't think my cams would cause a afr of 13.3 at idle though due to the fact that it is in open loop with the o2 sensor at idle.

above 14.7 is lean and bellow that is rich. When i blip the throttle it goes lean for a sec then rich to a prescribed amount which is normal but as soon as it comes down to idle afr is about 14.3-15.3 which is normal. but after about 30 seconds drops down to 13.3 at idle.

Yes rich is lower than 14.7:1 15 16 to 1 means you are lean.

if I'm not mistaken that's really lean. 16 airs to 1 fuel is lean right?
