rich afr with toda calibration

[jayson415]

Hi everyone, I have a 2006 Honda s2000 with fujita CAI,Toda header and invidia q300 exhaust,i uploaded the toda calibration and did a datalog and as far I know for a NA engine an afr of 10.1-10.4,is very rich or is this normal with this canned Toda calibration... can some one please verify the datalog and point me in the right direction, thanks in advance.

It is a bit rich for a naturally aspirated setup. You can try taking some fuel out, but your best bet would be to get this tuned on the dyno.

Will do in about a month, thanks.

One more question, if I go to settings, then overlay lambda input...closed loop and open loop what settings I use, stock sensor or corrected stock sensor?

[Spunkster]

use the stock sensor.
