Is the ECU in a 5-speed VE different than that of an automatic VE? My car is a 5-speed with a bad computer- Is it possible to use an Automatic Maxima's ECU? thanks-

 

Im pretty sure that the main difference is that the automatics ECU isn't progammed to operate the variable intake that 5spd VE are equipped with.

 

plus your clutch switch

 

Yes the two are different.

However, I think you can get the car to run using either ECU, it won't run great though. I may have this wrong.

 

car runs either way.

Automatic ECU will work in a 5spd just fine, except the Variable Intake will not work.

Manual ECU will not work with an Auto because it does not have the tranny controls that the Auto ECU has.

The 'clutch switch' thing is not an issue because on a 5spd that circuit is activated using a microswitch on the clutch pedal assembly, while on an auto it is a switch used to determine if the car is in the Park or Neutral position. No matter what its the same circuit, just a matter of how its wired on the car.

this is the second time I've typed it out, so search
