5896, FMU recalibration for 440cc (3:1 or 4:1) Posted by Stan2gnt, Jun-04-01 10:08 AM Due to finances and time restraints I must take the 440cc,AFC and FMU recalibration ($30) route for fuel enrichment. Recalibration available is 3:1 and 4:1 (and higher but defeats my purpose then). I'm thinking 3:1. Any thoughts? | |

5897, RE: FMU recalibration for 440cc (3:1 or 4:1) Posted by SaberKhan, Jun-04-01 11:16 AM Sounds good to me Stan. Now you can run the boost without all the sky high fuel pressures. =o) That, and it wont overload the Walboro pump. | |

5898, RE: FMU recalibration for 440cc (3:1 or 4:1) Posted by Corbin, Jun-04-01 02:08 PM I'm actually going to a 1.5/2:1 disk with my 440's. You have to order it separately from the S-FMU. That way I won't have to trim the fuel down so much with the AFC. I can't wait until I actually finish with my fuel system...I've had the turbo for a year and I'm still trying make a fuel set-up that I feel comfortable with. I am impressed with the stock ECU though, it'll run decently on any reasonable fuel set up. | |

5899, RE: FMU recalibration for 440cc (3:1 or 4:1) Posted by DarkOne, Jun-04-01 04:24 PM I'm going with 3:1 for now. I have one sitting with my pile of "not as of yet installed" crap.. Like my AFC and 440's. The way i see it.. i can lean it down enough with the AFC to compensate for the excessive increase in fuel pressure created with the 3:1 riser in my setup... there's only so much you can boost on stock internals. | |

5900, RE: FMU recalibration for 440cc (3:1 or 4:1) Posted by Stan2gnt, Jun-04-01 05:07 PM I'm going for 15psi with race gas on forged pistons and prepped stock rods (it only has to hold together for a weekend, then I can go back to sanity and if it doesn't thats life and the cars paid for). | |

5901, Corbin Posted by RAIZIN, Jun-04-01 05:27 PM What 1.5/2:1 regulator? Is it a recalibration disk for the vortech fmu? Didn't think there was one. Where'd you get it? I don't want my Cartech regulator.. want to put in the vortech but thought I couldn't go lower than 3:1 with it. | |

5902, RE: Corbin Posted by Stan2gnt, Jun-04-01 06:19 PM Thats why I was going with the 3:1 I checked vortechs website and the smallest they have listed is 3:1 http://www.vortechsuperchargers.com under accessories and fuel management. | |

5903, RE: Corbin Posted by DarkOne, Jun-05-01 08:44 AM It's the lowest you can go with the Standard FMU. The recal disc they're speaking of is for the SuperFMU... the adjustable one. | |
