What are good starting values for VSS pulses per mile and injector uSeconds/gallon?
For the injector numbers, please look at this post. The injector number can be fine-tuned after comparing the gallons displayed on the MPGuino with the actual gallons used to fill up. Repeat for a few fillups to get a more accurate reading. Multiply or divide the usec/gallon by the factor you are off in order to fine-tune the number. For the VSS, start with a multiple of 8204 for foreign cars and 10000 for GM vehicles. In order to get a more exact number, you need to calibrate it based on a known distance and multiply (or divide) by the factor that you are off. Repeat until you are satisfied with the accuracy.
