In what situation are you looking for more fuel? What problem are you trying to solve?

You can get to any fuel mixture your looking to get to with the SERT. Just set the desired AFR to the ratio you want once it's been properly tuned. The 14.2 limit is about as far as you can go and still keep it running in closed loop but that's not a big deal. Remember they've been running in open loop since 2001. If you tune the system properly 14.2 should be more than enough to keep it cool.
