I have tried searching with not much luck, are the ECU from a 2.5 and 2.7 interchangeable. Thanks |

i don't believe they would as the 2.7 has the "power valves" at the front of the intake manifold crossover pipe. |

The 2.7 flappy valve intakes only started in 2004 from memory so earlier year ones might work? That said, all of the 2.7 motors do use smaller injectors than the 2.5 motors. So I presume possibly different fuel maps in the ECUs? |
