The 2015 Cadillac SRX 3.6L ECM arrived quickly and was exactly as described. Installation was straightforward, with no complicated programming needed since it came VIN programmed. My vehicle fired up right away, and I’ve noticed improved performance and smoother operation since the swap. Definitely a reliable solution for anyone needing a quick ECM replacement.
