im not positive its an exact amount of teeth out,but i did align the marks on the pullies and made extra of my own on each side of both pullies and made sure they lined up with a ruler when i put the belt on, which i secured with vice grips as i put the belt round the rollers, so its couldnt be that badly off. | |

There is nothing you can 'tune' on the rollers on these engines. | |

Cursa is right, fiddling with the ecu aint gonna do anything if your valvs are opening and closing at the wrong time. i just went to vauxhall and they changed my timing belt and tentioners for forty notes. if you get the timing too far out you start to fcuk your motor up. then you will be paying a hell of a lot more to get it sorted. | |

The teeth control the camshaft which opens and closes your valves, if the inlet valve is staying open for a tiny bit too long, it's going to be open when the piston starts the compression stroke, throwing out some of your air and fuel, reducing compression and quantity of fuel. | |

if the ignition can be reprogramed then surely its just a matter of telling it to fire at the right time in relation to my new timing, therefore making the position of the teeth irrelevant.?? | |

The ECU can only adjust the ignition and fuel timing, not the cam timing. So sorry, back to taking the belt off! | |
