Fitting a 2015 engine and trans into a 2014 car - what to look out for?
 

New build of the 2015 engine I recently bought will be completed by Outfront Motorsports in CA in a couple of weeks and it will be delivered to EFI Logics in CT for installation.

Please advise if you looked into this and are already aware of the changes to the 2015 engine and transmission that should be addressed when they are put into a 2014 Monogram.

For example, apparently the coil pack harnesses are different on a 2015 from a 2014. What else? Thanks

You should likely use your old ECU as the new one may not be compatible with the dash cluster, but should run the new engine fine. There are sfa tuning changes between years.
