I need to know about ecm compatibility. Long story short I have a 94 f150 that was throwing 633 code and after days of checking wiring I have come to the conclusion it’s in the ecm. I pulled it and repaired the leaky capacitors and still had the same code coming up. I have a 96 f250 parts truck and out of curiosity I plugged the computer from it in and checked codes and it’s gone. Both trucks are 5.8 E4OD. The only difference is the 94 is an electric transfer case and the 96 is manual transfer.
can anyone tell me if I will work. All I have done was KOEO test I have not started the vehicle or tried to drive it with new ecm.
the 96 f250 ecm is on bottom in photo and the 94 f150 is on top.
The internals on both look exactly the same. Although I know that probably doesn’t matter.
F250/F350 use different emission setup than the F150/Bronco. The engine will most likely run just fine as well as the transmission. Since the F150 uses discrete TAB and TAD solenoids, the F250/350 uses a combined valve, you may get unexpected results when the computer is controlling the valves under different conditions.
Aur injection tube is between the back of the heads on a F150. TAB and a TAD solenoid to direct airflow as well.
F250/350 injects air at each exhaust manifold port. Also uses a combined TAB/TAD solenoid.
You are correct the intake manifolds are the same.
F150 uses two converters and a y-pipe. F250/350 uses a h-pipe and a single converter for the exhaust. The air injection tubing for the converters is different as well.
Verify the ECU pinouts between the years. Most likely the pinouts will be the same. As long as the ECU's are "speed density" and correct cylinders, they will run most times.
In past I have ran a 95 5.8L ECU in my 89 F250 302/AOD. Only issue I had was the 95 ECU was for a E4OD trans and I have a AOD. Bunch of transmission codes but the truck ran fine till I found a non E4OD ECU.

93 F250 has the crossover injection pipe at the back of the head.
I know this because mine is rusted out, AND the bosses are rusted
stuck into the heads...

it's like working on a Honda back there, but pokier.

If your F250 is a light duty version, then I would expect that setup. Just like the lighter duty trucks are.
If you have a F250 with a 8500 GVW or over, then you have another example of Ford's continuous exception to the general rule.
Need the interchange for a F6TZ12A650AJA. Any help is appreciated.
Interchange? probably not as you more than likely looking for another EEC for an RV.
But, since you need one for a 460/7.5l and Speed Density and E4OD, pretty much any SD48E hardware will/should work. There will be differences in shift points,fuel, and emissions though.
Ideally, you replace it with the same strategy/calibration code with BOX0.
More than likely, being a 1996, that is the latest and greatest produced, I doubt there is a newer one with a different revision.

It's truely and actually is a 1997 motorhome. I have the hydroboost on the firewall. The last gasp of the 460's. Yes, it's a BOX0. What is SD48E hardware?
