Truck was repainted, no stickers

 

This looks 88'ish to me:

 

These are potential EECM Numbers for 1988 7.5L.

Could be E7TF/E8TF;

E7TZ-12A650-BTC
-BTD
-CFA
-BVA
-BVB
E8TZ-12A650-BLB
-BMB

Additional potential #s


Electronic Control Module, 8-460 (7.5L), MT, ID E7TF-BT1C
Electronic Control Module, 8-460 (7.5L), MT, ID E7TF-BT1D
Electronic Control Module, 8-460 (7.5L), MT, ID E7TF-BT2B
Electronic Control Module, 8-460 (7.5L), MT, ID E7TF-BT2C
Electronic Control Module, 8-460 (7.5L), MT, ID E7TF-BT2D

 

How many vacuum solenoids do have next to your ERG Vacuum solenoid ? 1 or 2 ?

 

One I believe

 

So these are all compatible with my truck....or possibilities? If compatibilies, which is best? Haha

 

If one for sure, that may narrow it down to the 2 E8TF EECMs.

 

If you only have 2 solenoids (1 Thermactor) My best guess would be these 2;

Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BL1B
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BL2B

But let's wait until NumberDummy takes a whack at it.

Manual Tranny?

Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BL1B
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BL2B
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BT1C
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BT1D
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BT2C
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BT2D
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BTC
Electronic Control Module, 8-460 (7.5L), MT, ID E8TF-BTD

 

If this is it, then yes there is only one. And yes 5-speed manual

 

Then this has to be the wrong computer then....right? The number here is E8TF-14A608-DE

 

See this post;

That is a Circuit board #, not a Engine Computer #.

You could have the right EECM Remanufactured, maybe, but the remanufactured EECMs rarely have the original #s on them. It was most likely ordered of the EECM that was in your truck at the time.

So Number dummy has narrowed it down to 2 Calibrations;

E7 = 3 vacuum solenoids/2 thermactors

E8 = 2 vacuum solenoids/1 thermactor

So the EECM programming will take this into account for the KOER/KOER self-test and normal operation. So you want to be sure on your Solenoids and Thermactors.

 

So 3 or 2 vacuum solenoids/2 or 1 Thermactors

 

Do you know which one is your truck?

F-250: light-duty 3/4 ton (7,700 lb GVWR max)
F-250HD: 3/4 ton (8,800 lb GVWR max)

 

I sure don't. I'd assume it would be the HD having the 460 but that could be completely unrelated
