Need a Spot
I have a 4m40 with tranny headed my way and had a couple of questions. I have been able to find lots of great info on old threads but have not been able to figure out the ECU.

My question is : Since the 4m40 has a mechanical fuel pump, does this motor need an ECU, and if it does, what functions doe the ECU perform?

I am also wondering about the air intake. I have seen swaps with this engine using the existing air intake from the 3.0, but is it recommended to switch to the diesel intake ?

Thanks in advance for any advice.

Did you ever get the engine swap done and up and running?
