Does anyone have any experience with the Z1 OBD2 diagnostics tool? That thing looks pretty legit in its functionality.

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..
