Irrelevant until triggering is solved: Tuning is diagnostic, comparing one response to other responses, and you have nothing to compare against, yet. Use what you have and move forward. Also, 3.5ms is a very low number, and may have control issues at low loads. You have already been here, remember? You are opting to move from a fuel quantity situation to a control situation. This is not advisable. Until you have enough data to support a mode change for specific reasons, don't change anything except adjustments to the settings you have. Making random changes without cause is called "shooting in the dark", while ignoring what is obviously wrong - it's too rich. But, let's wait and see what it does when it's triggering correctly.

Thinking the fuel is the best place to start.When you get it operating as it should, then see if it is too rich. If so, then tune it. Change fuel — not how fuel is calculated. You have a data point. Work with that and improve it. Else a change in how it operates means starting over with what it does under that new setting. There is no indication anything is "wrong" with alternating, except that it is rich in WUE. Correct the rich. However, that requires a good warm tune that WUE adds-to. Put your socks on before your shoes. Trigger first, warm tuning next.
Checked the engine constraints settings. Their RF is at 7.0 for 7.0 ms with the injector staging at alternating. Change this setting to simultaneous and the time goes to 3.5 ms. May try this setting tomorrow.

Tune only that, as there is no clear data indication for changing anything else, yet, such as dwell. This advice will apply once it is running correctly on a good trigger. Find your socks.

All adjustments such as WUE are based on the warm tune. It has to be warm to tune it properly, so yes, warm it up. Again this assumes everything is correct and ready, such as triggering, so that tuning is on a solid foundation. Are your socks on yet?
