Air/fuel ratio during 2 step / anti lag

Post by bcumbie »

Can a wideband accurately read the air fuel ratio while you are utilizing the anti lag or 2 step?

No, during the operation of any rev limiter air is introduced to the exhaust system, so the lambda will show lean.

so how are you suppose to know if the a/f is correct and your not about to destroy a $15,000 motor?? how can we properlly setup the 2 step and not crack cylinders or melt pistons?

If the AF is correct at the same rpm and load as the 2 step, then it will also be correct when the 2 step is operating.

thanks for the quick response. just so im clear...even though im pulling timing out it will not affect the a/f no matter how much boost it is building? also what effect would enriching the fuel cause?

The timing doesn't change the AF. Adding fuel will obviously change the AF.

would adding fuel along with pulling timing help spool the turbo faster then only pulling timing by itself or is it not worth the added egt temps?
