When I bought my 5.0 it was with an automatic so wanting to be smog legal and got a computer from the wreckers. They sold me a 8LG. Worked great except no check engine circuit - check engine light didn't work neither did the plug. I just put in a 8LD and my light works! Smog here I come! Course it ran for about 2 seconds and died - now I have zero fuel pressure. If it isn't one thing its another..

turns out if I plug in the 8LG the fuel pump has power, but when I plug in the 8LD no fuel power but check engine light works, now if I could combine the two to pass smog..

I'm sure you'll get it... The power distribution amongst the computers is pretty standardized...

Now, all I want to know is whether upgrading to a stick shift computer for my 95 351 would help the performance now that i have gotten rid of the e4od and am now running an AOD....

Is is worth the $200 to find out?

hey if ya have a 88 auto comp. it wont matter if ya have a manuel tranny the 88 should have been an aod its not comp. controlled !
so my guess is run 8lg and fix the wiring prob. youve got somthing not hookedup or a brokin wire .

It is all in the factory harness, why would the light work with the manual computer and not the auto unless it is the computer? Why would the fuel pump get power in the 8LG and not the 8LD unless it is bad too? I need a third puter to test. Is the AL9 cali legal?

ya know i had an way off topic but applies 95 escort that would not shift .

it had a 91 engine and wire harness in it but with the 95 comp. it would not run correct put the 91 comp. ran great wont shift .

tured out to be both comp. were bad put new 95 comp. in runs great and shifts

so it may be the comp. :eek: i know its a long shot but i changed the tranny and wire harness in that damn car for nothing it was the comp. all along :eek:

I wouldn't be so hasty to jump on that bandwagon, Alx.

I found that the computers either work or they don't. My 4.0 kept throwing me a code 999 meaning hard failure, and when I checked it it said that there was a hard fault somewhere.

I just unplugged the computer, cleaned the 102 pin connector interface, re connected it and then everything worked fine, codes 1,1,1.

Hell, I got the 1995 E4OD in my bronco 2 to run/work well without the Vehicle Speed Sensor, passed the ref and everything.

But, that, is another story.

So you have a AOD running on your 5.8 with the stock computer???You arent getting crazy codes or anyting???What T/C are you running...If it is the 1356 did you have to do anything to make it work???Just wondering cause if my E4OD bites the dust, i can use a AOD (much cheaper) till, i can get the E4OD rebuilt...Thanks...

Of course not, I don't have any codes for it! if I did, I would not be smog legal according to the referee for California. (I hate the ref in this state. The man is so stupid, he can only think inside of his parameter box)

As for the T/C, keep in mind that all of this is under a bronco 2. The 1356 just wouldn't do. I run a 4.3 atlas 2.

I used a stock torque convertor for a 1989 351 and a 28 oz. flexplate from a car 351/AOD combo.

Codes are clear, computer is happy and so am I. yeah, I kept it a stock computer. It keeps up with my stroked out, bored out 392. Heh heh heh.

Nope. I was surprised too. My motor began life as a California 351W, which was speed density at that time and still is today.

Damn thing runs so clean that you can stick your head in the back of the flowmaster series 50 and not smell anything other than hot air. The smog machine says it runs clean, and that's with nothing more than one cat.

Nah, when you get your e4od out, I'll help you work the machine to accept what you want. The computers hold up well with mods and everything.

I know, I know the bennies of MAF. I run MAF on my 1994 4.0 in my 1985 ranger, and my 1988 5.0 HO in my 1985 Bronco 2. To be honest with you, I have yet to push the motor out of the dynamic range of the computer with cam, heads, timing, stroke, compression mods.

Computers always tell me everything clear, the machine smogs well, and have power. You just can't be afraid. Think of it this way, some other guy designed it, so some guy like you should be able to modify it.

It ain't no thang...

What AOD r u running???You are giving me hope...My E4OD has 177,000 on it and i am afraid it is gonna die...It stills pulls good, and i have a factory F-350 cooler on it so hopefully it wont die soon...I can get a performance AOD for a hell of a lot cheaper than a performance E4od, and i want to keep OD...

I am using a 1989 AOD. It has five wires on it.

Starter safety switch.
backup lamp switch
Neutral sensing switch.

Tuesday I picked up a 1995 F250 Computer for a 351/Manual Tranny.

I'll do some experiments this weekend and see what I can find out to tell ya. the diffs seem very minimal, but I'll know for sure come monday.

And yeah, I still have a 1995 E4OD with under 70K miles on it for sale..... In northern California. Shift kit and everything.

I run a 18" x 12" x 4" Jegs cooler. 5/8" tubing, with box fan on it. My E4OD runs at 150 degrees F.

I swapped out the 1995 E4OD because it had a variable line pressure servo built into it.

As you accelerate into a pull, the transmission will *slowly* push the fluid through the tranny, creating the softest launch possible. After a little while, it would spool up, which would *then* put the power down into the ground.

Their theory is that you are towing with this thing, and you do not want to leave your payload or tow on the side of the road as you try to race others.

Now come on, how am I supposed to do burnouts with this thing? I spent $4000 at the machine shop, and still did all of the labor myself to build a 392 stroker, and have crappy results from the soft tranny?

I know it's strong, and there are VERY few as strong as an E4OD. Don't get me wrong, the AOD is weaker than the E4OD. E4ODs rock. Especially in a diesel or lightning application.

But not a home built bronco 2 tire smoking wheeling machine. :(
