How long does it take to install an ECU unit?
can I do this or does a dealer need to do this?

 

There are 3 screws and a wiring harness to undo. Install should take under 15 minutes the first time, and under 5 every time after that. The hardest part is getting your head down there to see and your hands in there to undo the screws.

 

Is there any difference between lets say an ECU from an SE and one from a GXE of the same year? I'd think not, but I really need a confirmation.

Thanks.

 

dependson if the gxe has thc C&C package..... but the main diffreneces between se and GXE are speed limiter and rev limiter on gxe's

 

There's no difference in the rev limiter, only the speed governor.
