    300XS ECU on 250 Pro XS

    Is it possible to put a 300XS ECU on a 250 ProXS? I have a 250 ProXS with a bad ECU and a buddy of mine has a blown 300XS. I was wondering if the parts would be interchangeable.

    If you would, please review the Forum Announcements and update your thread with the Required Info. Thanks!

    While a 300XS PCM is not suitable for a 250 ProXS, it is also important to note that not all 250 ProXS or 250XS PCM's are suitable for use on YOUR 250 ProXS.

    Engine Serial Number would be a very important key in determining which ones are or are not suitable.
