The master fuel move was a quick fix to drop fuel across all zones. I'll go back later and actually tune the car (my WBO2 sensor is dead but I am trading headers with someone and won't mess with it for a few weeks).
Driving technique got me from 20 MPG to 24 MPG. Pulling the SC and dropping the master fuel (on a non-tuned rich car) got me from 24 to 30.5. I've got 440s in the car now and wondering if I should go back to stock injectors before I start tuning. I'd be able to sell the expensive injectors (or use them in another project) and I'm thinking the smaller injectors would have 4X the "resolution" of the larger ones. I'm not sure if that will really help me with fine tuning or not. On Fri, Jun 13, 2008 at 12:07 PM, Russ <[EMAIL PROTECTED]> wrote: > Makes sense to me (fuel map).
