Is the ecm on the standard 5.8s compataible with the the lightning 5.8??

 

An automatic 5.8 ecu will run a Lightning 5.8, but not well.

 

I was thinking in the opposite direction here....I have a 91 F-250 5.8 that I have put a roller engine with 1.7RR and GT40 heads and long tube headers. I was wondering if I could put a Lightning ECM on it, I didn't know if maybe they were a little more aggressive or what. My F-250 does have the E4OD in it. Any thoughts??

 

The issue with that is, the '93 Lightning ECU uses a "CCD" ICM/TFI module. It would require changing a couple of wires around.

 

Both of my 1993 Lightning's had gray colored Push-Start ICMs.

 

I've seen conflicting info, with some people saying their '93 Lightning had a black one. It gets confusing because that's a transition year.

Perhaps someone with access to the FSM could clarify what it should have.

 

Already checked: gray Push-Start ignition. As previously stated I had two 1993 Lightnings and I know 100% both had the same Push-Start gray ICM on them. I chased an ignition problem on the second Lightning for a few months before figuring out I had a bad PIP in the distributor.

My first Lightning was crushed by a tree:



I bought it back from the insurance company to use for parts.

The red Lightning was replaced with a blue 1993 Lightning:

 

Got anything left over?

 

The red L found a new home at BlueOval's house outside of New Orleans a few years ago. Bobby wanted a good drive train for a project truck.

I did have part of the hickory tree that fell on that truck made into a fireplace mantel. Every time I walk into my living room I am reminded of that fateful night

 

Sorry about the red one. I really like that blue one. Looks great and right up my alley. I think you got the best of a bad deal. BTW if that is THE tree in the background why isn't is charcoal?

 

I extracted my revenge on that tree, trust me! The tree in the photo of the blue truck was another one I took down as a precaution. Ironic the photo of the blue truck is almost the exact same spot where the red one was squashed.

This is what the first tree looks like now:

 

Pure awesome trophy mantel (pun intended). Justice is served. No disrespect but there are guys in East Texas that would be proud to use that as a bumper.
