You must really love drag racing.
There is nothing like beating a much faster car by beating them off the tree and driving well. Its great to tweak your car for performance and challenge yourself to be a better driver... but then again, you guys already know that.
My latest race mods have definitely improved my fuel mileage. Most race mods are targeted towards improving the overall efficiency of an engine and my tune was designed to dramatically increase horsepower in the 3k to 7k range which I am staying out of. The throttle response is amazing!
The attached data shows similar testing with additional data items added. The distance, instant mpg, and speed came directly from the obdII and I used the fuel usage vs distance to verify.
The end result was ~47 mpg (~41 mpg using the fuel level sensor) as calculated in a manner suggested in this thread and using two different data inputs. BTW, thanks SentraSE-R for the calculation lessons and the rest of you for your excellent comments and suggestions.
I elated with the results and will continue to run the '93 octane race tune' especially this week at the track where I plan to top 100mph (since I can't top 100mpg).
Also, I have a Scangage II (which I love) but you guys gotta try out the Torque Android app. It was only $5 to buy and the Bluetooth OBDII adapter is $40 on ebay. I'm even thinking of putting a tablet in my car for larger gage displays.
California98Civic, I am new at this so what is a BSFC map? Is bump starting using the clutch in 5th gear to restart after a EOC cycle? During pulse is it better to get back up to speed quickly or better try to get good MPG while accelerating?
Thanks!
