Question Can I get the application for MPGuino?

Hello!

I am trying to assemble the mpg meter for my corolla 2006. I am ok with microcontrollers and I have a programmer.
Could someone tell me if I can get the appliation or at least tell me where to read about how it functions? I need the info of what you are reading from the car and the formular of how to calculate the the MPG from those readings.

Thank you!

application here:
opengauge - Revision 165: /trunk/mpguino

basically, it tracks the amount of time the injectors are open and determines the fuel delivered from there

it also tracks the distance if your car has an appropriate speed sensor hookup.

thus it can track and display distance, fuel used, distance/fuel (mpg), speed, gph, and a few other permutations.

Me? no. Check the wiki, MPGuino - EcoModder

do take some pics and make a corolla wiki page if you sort it out.

ECM Pin 1 yellow wire is the number 1 injector wire.

ECM Pin 17 violet/white is the SPD wire.

Could not find one labeled VSS, hopefully the SPD is ok.
