Since we are quickly approaching the era of not being able to avoid electronic engines, if one is selecting a new one and is planning remote cruising, then it would make sense to find a manufacturer who will sell the necessary spares up front.
That likely may eliminate Deere and Cummins. Agco Sisu had no issues with selling a pre-programmed ECM and sensors and support kit.
