hey bigred, really if you want a good relyable truck, keep the EFI. it was designed to be alot more reliable than carbs. but you really need to know how the EFI system works. pick up a book at barns and noble called "Ford Fuel Injection, how to tune and modify" by carl probst. its a great book, very informative and it explains every part of the system. its a generic book, so it makes alot of refrences to smaller fords (probes, escorts ect) but its all in there. there is a COMPLETE list of 2 and 3 digit codes. and a detailed explaination of each component of the EFI system and EEC-IV.
i just thought id pass this on, i am 19 and sometimes think that carbs would be better too...but thats only when my efi is fouled up. but when it is working i wouldnt trade it for anything.

well then you can forget about going carbed. it would be way to expensive to go about getting the proper stuff to make it work. keep the efi and allow us to help you sort out the issues. you will be happy you did

Like kemicalburns said, stick with the EFI. Little better on fuel I believe.

p.s.- i have shorty headers, a kickass intake system, and ambition.
thanks for reading and i would really appreciate any feedback

I would put my vote in the "Keep EFI" pile.
I also have a '90 Bronco. I am always trying to find ways to improve my truck. I concidered trading the EFI for a Carb... Then I noticed all the really neat trail buggies have EFI systems. The reason for that is simple, it works better.
Anybody can build a motor with a carb and slap it in a truck. However, that is returning to the stone age... My wife drives a '95 GMC Suburban. It is almost 9000 lbs., with a 350 EFI motor, & a 3.73 rear end. It gets 18.8 mpg, no lie. How? Simple, EFI and a 5 speed tranny. My Bronco gets 13 mpg with a 351 EFI and the crappy E4OD, & 3.55 rear end.
I am looking to steemline the EFI also, but I plan to replace the tranny with a much better unit. A stronger but more effient tranny. Because in the end we all have to buy fuel. You can cut it any way you want. EFI will save you money at the pump.

Keep the EFI
I vote keep the EFI..(just inc ase my vote counts!) When I bought my 86 I did'nt think I would ever be able to work on it...turns out I was dead wrong. Bought myself a manual and along with this board and many more like it...I have been able to fix EVERYTHING on the truck thus far (need some wood to knock on at this point).
Some suggestions to clean up the engine bay:
1) Wire loom all existing wires under the hood, also a good opportunity to make sure you have good wiring.
2) I got rid of the A/C stuff, never worked since the day I bought the truck anyway (besides is'nt a window down at 55mph considered "air conditioning"?). Kept it just in case I have the time and funds to fix the system. Anyway you would be surprised how much space a bracket, compressor and hoses take up...I can actually get to my oil filter from the front top of the truck now! YIPPIE!
3) Thinking about doing a conversion with the dual catalytic converter system. If/when I do it I can potentially get rid of the air pump freeing up more space.
So there are just a few solutions!

I am doing this setup for 2 reasons:
1) the stock computer is programed for both the engine and the Tranny, which is programmed for the bare minnimum, basically for mall cruising. The stock programming for the tranny seems to be very soft and mushy.
2) I had upgraded to the mass air flow conversion for the engine which came with its own computer just for the engine. which left me with two computers. The new computer just for the engine and the stock oem computer was left in place to control the tranny
End result, after I install the Baumann's computer for the tranny, better shifting and opperations.
The conversion to mass air flow and sequential firing, instead of bank firing, increased the performance on the engine now it's time for the tranny.
Another note about the Baumann's computer, is that it is fully prgramable through a desk top or lap top computer.

Good luck with the kit. would be good to know how well it works for you. especially on a stock tranny. being a 90 model e4od i would have about 2000 bucks handy when that tranny lets go. up till 93 that tranny had lots of problems and was very weak. you start increasing the shiftpoints and firmness and you may have problems on your hands . not to rain on your parade but thought i would let you know early rather then later

All things being equal, there is no bashing here. Everything that has been said so far, is very informative, even for me. And, since I have done some research on the E4OD, that maybe I could share a little of what I have learned.

I Learned something. I have heard good things about the stand alone computer for the E4OD. They are a very strong tranny when re-built with all the upgrades. Please let us know how it goes, as far as difficulty and the outcome.
