Narrowband simulation works off the same voltage you're using for your wideband signal, which should be 5v white wire on that AEM.
You need to make sure you have a functioning wideband sensor set up in link and if that's off, so will your...
Step 1 of all wideband gauge/controller vs. ECMLink logged value investigations is verify your positive and negative wiring for the gauge, as Curt mentioned above. If the AEM controller and ECMLink don't agree on what 0V is, you'll be chasing...
"Displayed" values and "Captured" values are two different menus. You need to "capture" CombinedFT (or more precisely its component parts) before you can "display" it.https://www.ecmtuning.com/wiki/ecmlink101datalogging
This covers essentially every boost control configuration you would ever need to consider and the benefits of each. See if this clears up your questions.
I have a 2G. I had to swap the MAP sensor from the Baro input that ECMlink uses through the factory MAF connector to the MDP input that would have been on a factory 2G car. I have also found that the PnP adapter default tach output seems to cause...
https://www.fs.com/c/copper-patch-cords-960This vendor is favored by many of the 'homelab' YouTubers and Subreddits. Mostly for the optical stuff but they have a large selection of copper stuff. Might be worth a look to compare.
