I just cant get my head around the std map sensor living with positive inlet pressure, the s/c cars have the throttle body and map sensor mounted before the charger whereas a turbo has the opposite I'm going to phone chip wizards tomorrow to see what the man says |

Perhaps the ecu can accept a different map sensor? ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

On the SC-6, the map sensor (and throttle for that matter) are on the suction side of the supercharger. That'd solve it. ________________________________________ Ex SC-6Now in a Megane R26 |

that would be ideal, but surely if it could then wouldn't rich have done this when he developed the s/cconversion? |

yes i know that, but the sensor is between the actual compressor wheel and the throttle valve so wontactually see positive pressure |

The fuelling therefore is guessimated by using 'fictious' boost when using the standard ECU.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

But then how the feck are these xsara boys doing it? was there not a ZX turbo on here a while back? |

A turbo setup where the MAP sensor would need to read boost to my mind is out of the question, therefore I don't know how they're achieving it to be honest on the 1AP ECU.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Better off going dta... The 1ap cant see positive boost thats why rich worked draw through setup. There is a 6ap i believe that was fitted to some euro s16s which use a 3bar map sensor...
