If you have the ecutek Bluetooth obd Ii interface and the ecutek app that’s all you need in my opinion. I run data log nearly every time I drive my car with my ecutek setup.

Ecutek dongle came in the mail to day and I already got Z1 a couple 3rd gear pull datalogs and a couple others just cruising around. They let me know which parameters to be sure I had activated in the app.

So now just waiting to hear back.

Is it possible something in the tune itself is wonky and causing it to misfire?

I will definitely update this thread when a solution is found.

Does it make any sense that I feel like the car runs better as the fuel tank gets more and more empty? Because I've been through two tanks of gas now since this issue started and I feel like I've noticed this both times the fuel level got closer to a 1/4 tank.

I also feel like the car is running better now since I've been using the ecutek dongle. I know it ran an update the first time I plugged it in and got it connected to my phone.

This ecutek bluetooth dongle coupled with the phone app really is quite an amazing product. I was able to record datalogs and send them straight to Z1 from the app.

Car hasn't thrown the code on the dash since I got the ecutek dongle...it pops up sometimes in the DTC report in the app but it clears on its own after a drive or two.

Weird..
