The 360 ECM will work on the 318 provided you are using a ECM from the same generation. Now in terms of performance you will have a benefit because of the fuel map and the cam that is in the 5.9L, the 5.2L cam is better in terms of lift but the 5.9L has better duration. The MP ECM is the best choice because it's completely unlocked you can program the hell out of it, a stock 360 ECM has restrictions. Not saying you cannot program a stock 360 ECM but the performance one isn't going to limit you quite as much. The thing about the ECM is the EPROM holds the calibration so provided you can remove the chip and write programs you can modifiy the stock ECM but it's just not very practical.

The worst part about the ECM is you can spend thousands on the engine but you won't take full advantage with the stock ECM that's speaking if the ECM accepts what you do to the engine.
