For those with D-Jet, what are you typically seeing for A/F ratio on a medium to hard overrun? Based on what I've read here mine seems too rich - like in 10's and 11's. Once the RPM's drop closer to idle it bounces back up to normal idle A/F ratios. Does A/F on overrun even matter?

I can't speak to your A/F on overrun. I had my rebuilt MPS bench tuned by Jeff Bowlsby to 2056 specs over the winter and slapped it on. I don't think the car has ever run better.
But as far as gas mileage - what cam are you running in your 2056? My combo runs 20-22 MPG around town and 25-27 MPG on the highway with a very mild FI cam (FAT 440 MP). |
