cheaper to buy a megasquirt and leave the injection part unplugged!

and I've measured the distributor plug hole a few times, but just can't remember the size!

Hi folks, Just thought I'd share my latest improvement to my car, which is a NoDiz kit - which I believe is like MegaJolt. Basically a black box (any box which is black is awesome right?), a Ford Focus coil, a crank angle sensor (with 36-1 crank wheel) and for my turbo application, a Cosworth MAP sensor. All rather straightforward once the crank wheel and sensor are sorted out; black box mounted on firewall, a six (or so) wire loom running to the coil & MAP sensor, and a second 3 wire loom running to the crank sensor. It's not that cheap, but allows for ignition mapping on a laptop, so less visits to the dyno I guess, plus it has a digital dashboard for smartphone, so no need for tacho (and it has a rev limiter). Not quite running on it yet, so for now I effectively have two ignition systems fitted. Once I've got it bedded down I'll blank off the dizzy hole and throw the coil away. I read somewhere that a welch plug will do that job.. An interesting feature is that it's "wasted spark" system. That is, it only knows two things - fire on 1&4, or fire on 2&3. Compressed fuel and air in cylinder 1, and nothing in cylinder 4, but both get a spark! The wonders of modern technology.... More info here www.nodiz.co.uk. |

I also have wasted spark ignition (MegaSquirt 3). I think you'll find that you will pickup more torque at lower revs. I did. Jim |

Sounds like it works the same as megajolt And yes you can just use a welsh plug to block the hole in the block, can't remember what size but it's easy enough to measure. Or there was someone here on ausmini that made some cnc'd blanking caps. Should be worth the effort you put in getting it installed and setup. |

Thanks for the replies guys. I still can't believe how far things have come for the humble A series - imagine telling someone in the 60's that it would be possible to have no distributor, a phone mounted on the dash as a tacho, a rev cutout and computer based timing adjustments! And then telling them that a cheap GPS could tell them speed with much greater accuracy than the speedo?! And that's without even going into replacement heads, fuel injection, and all the other goodies! |

Sweet Jebus! Can I ask, how did you mount the 36-1 crank wheel? |

Either or. I had a feeling they were smaller than the outside diameter of the wheel. But that makes good sense. |

You might say I cheated - got a new assembly from MED, and their sensor on mounting. It was the "no work" option! Does all fit up nicely though. I did look at the other systems available, but ended up with the NoDiz. Just can't remember why right now! |

When i fitted mine, I turned down the outer of the balancer and then a 3 points i drilled and grub screwed the toothed wheel and the pulley together, the only pic i have though is with the wheel on but not using the grub screws yet

i just use a dividing head & machine the teeth out of the pulley |

Well I got it running on the NoDiz the other day, but have no idea whether the base map is any good at all for an A-series. Does anyone have any suggestions? I did find this data in the Haynes manual for a A+ 1275s, but it's so vague as to be useless: 700RPM 0-4deg 1600RPM 8-12deg 2500RPM 16-20deg 2800RPM 23-27deg 5200RPM 24-28deg For what it's worth, NoDiz provides for advance settings at these RPM points: 800, 1200, 1600, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 5500, 6000, 6500, 7000, 7500, 8000. I took it around the block on the base settings, and a familiar flat spot was noticeably absent - awesome start! Thanks Matt |

Have a look at the CSI ignition advance curves.... more advance earlier |

Thanks guys. Will check those out. Though nothing quite like a trip to the dyno, near enough will make it driveable (and better than with a dizzy). Cheers |
