Which ecu is better
Im starting to look for an ecu to swap my 1990 F150 to mass air. It's got the 5.8 with e4od transmission.
Apparently there is three computers to choose from.
HOG1, HOG0 or VEX1
Which one of these is best for tuning. Is one of them sequential or are they all batch fire. Or which ones are which.
I'd like to just stay with batch fire to make the swap easy. Then I only need to swap and add only a few wires.
The plan is to put headers and full stainless exhaust.
Then will be ported heads, roller cam, roller rockers and injectors.
After that I'd like to get a custom chip for it.
That all will happen for sure....
I have an idea for a blower setup that will come later if I ever get some spare time in the garage.
Anyway. Is there any of those computers that are better for tuning.

All three of those are Sequential, there is no batch fire Mass Airflow PCMs out there that I am aware of.
As far as which to use, check with the tuner of your choice to see if it is supported. I think they all have aftermarket support, but I would not say that with 100% confidence without some verification.

Good point on asking the tuner. I didn't think of that.
No big deal that they are all sefi. I just was being lazy. I'll grab an injector harness off one of my parts mustangs and that way I'm not cutting up and soldering tons of new wires.
Sweet, thanks.
I think I have the ecu pinout of my current ecu, anyone have one for the mass air ecu so I don't get mad at my phone searching for it...

I can remember when that website was first started. I'm glad that it has progressed throughout all this time.
Great info.

Well
A few questions sorta...
That website shows it as batch fire. It's not listed that you need to add injector leads or even maf wires. I'm not understanding the spreadsheet apparently.
(hard to type on phone and see the differences)
Do I wire it like the 94-95 mass air truck and make the changes listed in the right hand column for the e4od trans or what do I do.

Oh... Is he list on the left for a manual trans and then the one on right is autos...
So the 2nd one from the right is what I make he 3rd one to the right look like. Then it will work.
Sorry. I think I got it now. Been a long day at work. Sheesh

Got it
So it's insinuating that the mass air ecu is still batch fire.
Cool
And you only need to repin 4 wires which is kickass.
Very easy.
But where do you add the mass air wires.

I'm assuming you are using the fms piggyback adaptor to attach your harness to the ecu...

No it is not insinuating you only need to add 4 wires. Mass air PCMs are not batch fire.

Yes, I use a jumper harness on mine which came with an AKC0 ecu. I used that same ecu to replace an HOG0 on a 94 F-150 (mass air from the factory) and I made programs with it using an HOG0 database. Only downfall to using a 2wd ECU (with an electronic transmission) on a 4wd rig is that you wont be able to utilize 4-low.

the second column over says e4od additions but not saying that i need to add mass air wires or injector wires. Thats why I thought it was batch fire.

Yes it does show where the wires for the MAF goes as well as the injector wiring. The column labeled as "additions" for MAF trucks with E4OD transmission is also clearly marked.
I am not here to defend Ryan, but I will say you need to do a lot more research before tackling this project.
