engine swap
i am swapin a 4.9L with a 5.0L. now my question is what ecu do i need? i have a 89 f150 4-speed 4x4. i know i need a 5.0 ecu but i have had some people say that any 5.0 ecu will work and i have had others say that i need a 5.0 4x4 4-speed ecu. i think just a 5.0 ecu any manual style will work but i need to make sure so i have it in hand instead of finding out the hard way..

89 was the first year of the E4OD in the F-150. That's a moot point because the OP has a manual tranny.
It's not the 0.1 liter that's the issue - the 4.9 is a slow revving torquey inline 6 that has zilch horsepower, designed to WORK, not go fast. The 5.0 is a small block short stroke V8. It's going to accelerate a lot quicker but it doesn't have the low end grunt of the I6. It's probably going to get better gas mileage and feel a lot peppier until you start trying to do actual work with the truck.
I believe that 4 speed stick has a granny low - that will compensate a LOT for less bottom end torque.

hmm!
well i knew this was a hard one but i dont know. for putting a 5.0 over a 4.9 thier is a big difference, and its not alot of work to swap out motors in this year of trucks i just not to sure on the ecu question that i am having a hard time gettin a answer for. i have been told more than not that a manual ecu will work but just curious if it has to 4x4 too.
and for any parts let me know witch ones u are looking for?
