Isn't the Megajolt designed to run specifically with Ford EDIS + Coilpacks? How have you wired the Megajolt to the Hyundai Coilpack? http://www.turbominis.co.uk/forums/index.p...tid=469104&fr=0 |

As above. Iirc Unless you’ve installed coil drivers into your Megajolt you’ll need to use the Ford Edis unit.

It's been designed to run any wasted spark coilpack, drivers aren't needed unless you're using big draw items like LS1 coils etc. The excel unit is smaller and identical wiring to the ford unit. I'm getting great spark from them. I have another day off today and will be trying a few different things to get it going.

Fuel pressure waaaaaay too high, am trying to source a restrictor fitting to bring pressure down to a reasonable level.

Ah yes, I've wired the coil pack backwards before. Hope you've got to the bottom of it. Always check the basics for the signal too, trigger wheel position and gap for sensor. |

The standard FPR should be keeping pressure at 3-4 psi at the carb, excess fuel should be returned to the tank or back to suction side of pump (T piece). If your pressure is way too high and the FPR is ok then you're plumbing is wrong and a restrictor won't help. |

Tank -> filter -> T-> EFI pump -> fpr-> carb It's not the original malpassi fpr but do have one kicking about. Do I swap back to it?

When you say your fuel pressure is way too high, what is it?

What size is your fuel return pipe? |

All AN fittings etc, has all the right fittings plus pressure gauge. Unwound it still hits 20psi. Return line is also 3/8. “A turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.” - Jeremy Clarkson |

You have an EFI FPR by the sounds of it. Useless on a low pressure system unless you have the largest return pipe known to man. |

I would be using the standard turbo pressure regulator, if I recall delivering 3.5psi. If In good order fuel pressure will rise with boost. On 7th Oct, 2010 5haneJ said:

That will be for fuel injection and designed to run at about 45 psi / 3 bar. You need the standard Metro Turbo type regulator for a carb installation, which will run at 3-4 psi. |

completely wrong reg, total waste of time doing anything until you have sensible fuel pressure.
9.85 @ 145mph

The metro turbo also had a resistor fitted to the fuel pump, if your running spi or mpi fuel lines it may help in lowing your fuel pressure. Own the day

various options here depending on which direction you want the pipes pointing.

New Aeroflow fuel reg. Best money I've spent yet. AN lines... Will eventually go down the AN all the things, but just need to get it good enough for dyno next weekend.

I did look at the Aeroflow ones as well, but didn't see any with a pressure reference on the top for boosty use. 9.85 @ 145mph

AF66-2059BLK 2 supplied springs for 3-20 or 30-60psi, small, well made and has a great constant regulated flow. 1:1 boost reference.
