Summary of change:
Measured fuel consumption: '''1941 km / 1 liter gasoline'''. '''Controlled by VEMS''' (of course). Next goal is 2000 km / 1 liter gasoline. A low-consumption daily driver runs appr 10-16 km / 1 liter gasoline. But this is a competition car, admittedly not very convenient (and unsuitable for bumpy roads), of course. Among the world's [http://www.eco-marathon.hu/ most fuel efficient vehicles] with internal combustion engine (battery and fuel cell are different technology and 1 MJ to 1 MJ based comparison that journalists often practice makes little sense). http://www.eco-marathon.hu/galeria/verseny2/06_t.jpg * low drag (Cd ~ 0.1 - similar cars often claim 0.08 - it's hard to measure exactly) * appr 20kg (without driver) ** 20kg is '''record weight''' in its class. The next in this class is above 30kg.

The max PWM duty of the IAC output need to set lower than 50% (this means 6V effective maximum)
