Fuel Injection and Barrett-Jackson

statesblue · Post by **statesblue** » January 22, 2009, 8:46 am

I was wondering if there was anyone on this site who makes fuel injection wiring harnesses....or does anyone know of a good outlet other than the obvious like Painless etc.. Even someone who can alter the factory harness.
Anyone watch the auction? You would never know the country had any money problems buy the prices they were getting.
Seems that resto mods are becoming very popular. The ones I saw go across the block did a lot better than I thought they would.

www.fordfuelinjection.com has all the info you need to gather the correct parts for the conversion AND they carry harnesses and other parts that you may need or may not want to fab on your own. The 5.0 EFI harness for our trucks is $475....not cheap but with all the factors involved it may be a bargain.

The big question is what FI system you have, do you want to be able to reprogram your ECM if changes are made. Why I ask is I have a drivetrain in my 63 from an 88 F150, with wiring from the 88. This has the computer and all. Because I have eliminated all of the smog control equipment, the truck runs rich, and the programmer I have been to in the past suggested pulling a ECM out of a late 80 GM with the throttle body injection. The cost for me to have it programmed is 60% of what it would cost to program the Ford ECM. Haven't done the swap yet but the wiring diagrams are available, just going to take some time to put it all together.

As for BJ auction, prices are much lower than they were a couple years ago.

There is some pretty cool stuff out there for late 80s GM fi computers. You can get all of the stuff you need to program it yourself. There is one setup that uses flash ram (I think it's ram, anyway). You can have different timing and fuel maps, say one for economy and one for performance or towing. All you do is turn off the vehicle, flip a switch, turn it back on and the other map is used. Pretty cool, I think. I have an 88 Firebird so I've looked into this. Don't have a clue what's available for Ford injection.

Man that wet plenum intake will drive the system insane....all they are are bad design throttle body injection not much of a step better than a good tuned stromberg carb...

Ask yourself why no Auto MFG on the planet uses this system anymore...

Dean i have the 88 5.8 7.5 puter in Christine.. I only removed the air injection system and she runs fine. What all did you leave off?

My street rod buddy always uses The Detail Zone for his projects. He has powered his cars with 460 EFI, 4.6 SOHC, and 4.6 DOHC, and 5.4's

My vert is a TBI car, lol.

I didn't notice the intake, first thing with pics that popped up in a search, lol. That is an adapter not an intake, lol. On a good Stromberg intake they are supposed to work VERY well. I don't think all out performance is the intention of the piece though - more of a nostalgia look combined with modern EFI livablity.

I have already been on fordfuelinjection.com which is by far the most informative I have found so far.
For my truck I will be using the injection from a 91 T-Bird. It is a H.O. computer similar to the Mustang.
Not sure about the motor. Have a older 302 that I might rebuild or maybe I will search around for a 5.0 motor. Anyone in Az got one?????

A wet manifold will work great for throttle body injection. The fuel has to stay in suspension just like a carbureted system and that's one of the things a wet manifold is designed to do. Shallow manifolds might need a spacer under the throttle body to prevent puddling on the floor of the plenum. I know of plenty of people who have installed throttle body systems with great, much improved, results over a carbureted system. The thing with TBI and most any other form of efi is that a computer, rather than screws is used to tune. For some people it is a tough concept to grasp and so EFI systems are attempted but written off as no good because the user doesn't understand the technology. Just like tuning a carb, tuning efi requires practice in order to become proficient.
Using a dry manifold on a wet system will not work so favorably.

A single four venturi TB will work on wet single or dual plane without a plenum, But not well with 3 2V Tbs on a plenum...sure the fuel gets atomized but the dead zone areas present in the plenum will allow clumping and re gathering of the fuel unlike with individual runners on a small plenum on a normal intake. You wont notice until the cylinder walls are wiped due to lean and fat fuel delivery, the HEGO will drive the system insane trying to keep up with the correct ratio.

To make an open plenum work like the one shown you need RPM to keep the fuel in suspension. Just like a tunnel ram it will load up at low rpm and stutter and drive the computer batty...

A TBI is a step up from a carb but not in the application shown.

All it takes is a good stereo...........
GREAT set of schematics..........
And NOONE to bother you............
Oh yeah........TIME

I did my own setup in EEC-V OBD 2 of which there is NOTHING available!!

It works fantastic although I do want to get it set up/checked out to be sure its all good.

And when you are done----there is a great sense of pride and the knowledge gained is invaluable.

GO FOR IT!

Did you cure the 40 MPH yet?

Agree The wiring may look daunting but it is point A to point B. fairly simple...Just like turn signals or an oil pressure gauge. The terminals on the computer go to point A or poll A+B ect.
