EFI question

[chomama1]

Anyone using any of the modern self-learning EFI systems? I like the new Holly Terminator and the Atomic MSD. I have a 302 with the stock ford EFI and I just don't like the look. Can't really afford the ultra cool stack EFI.

I live near Winchester, VA. Who in that area, MD - VA, can install something like that for me?? Any idea of installation costs?? thx.

"self learning" is not 100%. The self learning mode will get you about 80-90% of the way. But the rest is up to you or a good tuner. Dyno time is preferable, it's quick and efficient. And some things are trial and error - like cold start curves and altitude changes.

chomama1 If you have some basic knowledge you can do this yourself. Most systems are built to be easy to install. The programming is the pain in the butt. Get a complete FI kit to match the motor. If this motor is not stock you will need to match up injectors to it. Rick L. Ps there is no 100% self learning system. They will get you in the ball park but need to have the timing curve setup, fuel pulse, operation of the motor temp from cold to hot. Some systems have a distributor that has both crank and camshaft sensors in it. It MUST be phased to the motor for correct top end center on #1 cylinder. Some systems have a crankshaft sensor or trigger for top dead center. You will need to use their O2 sensor from the kit. Need to see if the kit has 1 or 2 O2 sensors. Some run on 1. In this case get an A/F meter to reading the motor. IF they offer, get a wide range O2 sensor kit. Power adder kits use them and you can add on a blower, turbos or NOS down the road. I good fuel system setup is needed. A 3/8" min supply line to the injectors and 5/16" return line. You can use a dead head system but IMO I don't like them because of small debrie in the gas will endup in the fuel injector rail and the screens of the injectors causing flow problems over time. Find the best fuel filter. Want a 5 to 10 micron filter. This will help keep clean and catch 98% of debries in the fuel. Good electric fuel fuel with a 30- 80 psi rating. Keep as close to the fuel tank as possible. Most external pumps don't have good suction. There is also a kit for installing a fuel pump in the gas tank. I made my own back in 97. Check with Jegs or summit. Good luck Ps use 10-12 gauge wiring for this and 40 amp relay. Insolate the fuel line if possible with shielding or wrap to keep down the heat and protect the lines from damage. Side note, no rubber if possible. The ethohol eats the rubber over time and makes little black balls that endup in the fuel filter or injectors. Need to keep eye on this after 5 years or change the lines. I when 12 years and the lines came apart in the gas tank. Easy fix. Good luck. Rick L. IMO FI systems are great for all around drivibility of a car. They don't make more power than a carb or a set of webers on a motor. They do self adjust better with driving.

Wow, lots of info.
Yes, I would definitely get the total kit from the manufacturer, fuel pump, lines, etc. Ditto for wide range 02 sensor. I don't like the idea of a return line, but I think I understand the problem with the deadhead system. Fuel pump in the tank - got it! Thanks for the info. Any recommendation for an installer? God bless me, I'm just too stupid to do it on my own.

You should consider a Mass-Flo system. Has the look (kinda) of a carb, but it's port injected EFI. It uses mostly stock Ford components, including the computer and fuel delivery system.

If you call them, I'd almost bet they can recommend an installer in your area.

I have a mass flo on my Roush 427sr and it is great! Other than the fuel rails it looks like a carb motor

MassFlow is no longer using the EEC4 from the 89-93 Mustang GT - which was a A9L code. They are having their own ECU built by the same company that supplies Ford. From what I read it comes with the software to change anything you want to change. It may even have data logging. It looks like a great system, but I have not experience with it.

There claims in the past that it was plug and play system was kinda true if you put it on something close to stock, but frankly I considered their claim to be BS. However the concept and looks was great. It is definitely worth looking at.
