Has anyone used a FAST EZ-EFI unit on a slant six yet? |

Nope, but it looks like you could rig something up with their multi-port set-up using the same size injectors as the v8's you have to steal them from. Frankly, I wouldn't go this route. I love the idea of the FAST EZ-efi and don't think it is that expensive for efi, but it's almost have to be a 350 size engine and such.... oh well |

IF you can put a 500 cfm 4 barrel on a Slant six, I'm sure the EZ-EFI unit would be better and more efficient given the injectors are computer controlled and it's optimized for best air/fuel mixture. I'm planning a Hyper Pack 225 with the FAST unit in mind. A camshaft with a little attitude and a 4 spd stick and the turn-out should be right as rain. |

Yeah, give it a try! I'm a little worried that your comparing a 500cfm Edelbrock carb to four (4) 65lb injectors? Just to give you a ratio my efi runs twin 55lbs off of a 350 and has never has cycle duty problems! This system is design off of the 350 and has feed some 600hp big block (according to the vette guys), I wonder if Fast has some smaller injectors? |

I wouldn't doubt it. I've sent some correspondence their way asking just such a question; I'm awaiting their reply. I'm sure the system can be modified. I'm also curious as to when they come up with a blow-through unit for Forced Induction applications. |

I remember that article, the gains they achieved by using multiport injection were pretty solid over a carb. Unfortunately, that setup is the more expensive option. If I had the dollars to do it, I'd give it some serious consideration. |

If cost is in consideration, than the EZ-EFI still isn't the greatest option. My buddy is planning this for his 360 Dart and he is going to be in the whole setup for over $2000. Call me crazy but that is more than I've spent on both my slant six and tranny stuff. However, it would still be a great deal if you could get some smaller injectors in it and have them change the basic fuel requirement in the program, than it should be a great easy set-up. |

My Ford friend is pretty warm on the EEC-4 engine management and they made them for a 300cid 6 cylinder truck. He likes the self adjusting feature, basically it learns and tunes itself to the application. I looked at the schematic and it does show a vehicle speed sensor though, which might be a little sticky to rig up. The 8.8 rear has a sensor and wheel off the ring gear..There is always megasquirt V2.x at $110 for a kit. Not bad, but that is only the driver, you need to supply all the other sensors and injectors, plus HP pump. It adds up. |

I have not used the FAST products but I did just put on an EFI kit from professional products (professional-products.com). The kit i bought is a Powerjection 3 that bolts to a 4brrl intake. This kit seems like a simpler setup than the FAST and is easy to install. I think it is cheaper also. The longest part was running all new fuel lines and returns for the fuel pump and fuel injection return. After I got the system bolted on, hooked up the 5 wires I plugged in my laptop and set it up for a 6 cylinder with 300ft lbs of torque, I also set it on the auto learn. After that I hit the key and it fired right up, I let it idle about 5 minutes, then took it out on the road. It pulled very strong up to about 5500 rpms and ran smoothly. It did have a mild "sputtering" because I had some vac ports unplugged. It is supposed to self learn as you drive, so I need to get it out and run it now that the vacuum leaks are fixed. You can also use Professional products EFI kit with a blow through turbo charger up to about 21 pounds of boost, which is what I am hoping to do down the road. I have less than 20 minutes driving experience with this kit so I can not give any experienced advice yet, but so far it seems to work well. Because I have a repair shop and a tax license I got set up as a dealer with them (mainly for personal use) but I get a good discount on the products and can order anything for anyone who is interested. I will keep you updated as I get to test it more. I need to put a transmission in the dart before I can do any more testing so it may be a week or 2 before I really get to put some time on it. |

Very nice. Please, let us know how it develops for you. Any particular changes you've noticed after long term driving? |

That product learns even under boost? That is impressive, but I was nervous that the computer was under the hood. |
