After snowing here every day for the past week or so, we finally had a sunny day so I could sort this all out. I had removed the Dinan ECU last week and installed the bypass plug and the car was driving just fine. I reinstalled the Dinan ECU last night and....it's working!

Using the Dash Command app, I did a 0-60 run in 4.9sec compared to about 5.5sec with the bypass plug installed. This wasn't using launch control; just mashing the pedal when the light turned green. I don't think the Dash Command app is very accurate, so I'm sure the car is quicker than that. I just wanted to verify that the tune is working and that the car is faster than stock (ie.,with the bypass plug in place).

Maybe the Dinan ECU just needed a hard reset or something, but it seems to be working well now. I'll probably do some more 0-60 comparisons between Dinan ECU and the bypass plug once the weather warms up. It was in the low 30°'s when I tested the car earlier and the roads were also a bit damp.
