Sorry for the confusion on the A/F numbers. The Dyno run I posted was logged prior to final on-water calibration. To clarify our A/F ratio data I posted a graph generated by our onboard data acquisition system used during water testing and calibration.
Note that as engine RPM increases A/F ratio improves. This is because our ECU's fuel mapping is boost sensitive and will deliver more fuel as manifold pressure increases. Our mapping will cover a broad range of modifications due to its robust fuel and timing maps. Stage II through Stage III-plus will be adequately fueled without the need for additional fuel system enhancements.
Again, sorry for any confusion created on our part.
