Adamw Posted March 29, 2020 Report Share Posted March 29, 2020 Either would be fine. I think you would be in for similar money by the time you buy 3 extra probes for the AEM (from memory the only come with one in the kit). The Internal & Link CAN lambda would give a couple of advantages in terms of being able to disable closed loop lambda or ignore one of the sensors from lambda average if one reports an error, also since they have bi-directional communication they know when the engine is running so they can apply the proper sensor warm-up sequence during start up. I used to have a AEM 4ch on my dyno a few years ago and it worked well, it gave good sensor life and reported similar lambda to my good wideband that I trust.. The only downside is it uses the older LSU4.2 sensors which are becoming harder to find and a bit more expensive nowadays. I have a Link CAN template for it somewhere.
