Hi everyone I was just thinking about how I am going to get my speedo to read right with 31s and a 4.9:1 because as far as I know when I install the g16b baleno engine the ecm needs to know the ground speed for the fuel efficiency thing and how will I get it all to read right to get good fuel economy out of the engine. |

no one really bothers. i think you can get a gear driven speedo correction box made but seems like a lot of effort. my baleno motor ran fine with no speed correction and similar gearing to yours |

What sort of L/100km did you get with the baleno on 31" |

The baleno ECM doesn't need to know the speed accurately, only that that car is in motion. Steve. |

I was averaging 9-10/100 on long trips 10-11/100 around town |

Sweet thats pretty good How did you guys make your speedo read half way right because as far as I know the speedo cable is driven by the output shaft of the transfer case Or am I better off just using a gps |

no one bothers changing it. just check it against a gps and remember where different speeds are. |
