Hey,

Is it possible to replace the ECU in a 2.5 V6 with one from a 3.0 V6 or 3.2 V6? (I am lead to believe they are the same)

Although I am getting my 2.5 pulled out and a 3.0 put in it's place in around a month, should I just wait until then or will it be incompatible with 2.5 electronics?

Thanks

You don't even need to change it, especially since there is NO 156 3.0 V6 from factory.
And no, 2.5/3.0 ECU is different than 3.2 ECU. 2.5 and 3.0 should be the same, but as I said, you do not need to change it, it creates more problems than it solves, like having to reprogram the keys and such.

I've done the same; the engine will run on the 2.5 ECU, not correctly but it will run - then get it remapped and all will be well :)
