Grand Prix version 22.0.4 on the last version of iOS 11 on an iPhone 5s. At an autocross this weekend, every time I started the car before a run, the app would crash to the desktop just after the coolant temperature appeared on the Timer screen. It also crashed on the home screen after starting the car. After restarting the app with the motor running, it would work fine for the run. This didn't happen with version 21, or at least not consistently. This is an unmodified BT1. It doesn't work with the BT1 app in iOS 11, but it previously worked fine with HLT.

I can't reproduce that here. Please check if you can find crash logs on your phone:

• Settings app ‣ Privacy ‣ Analysis ‣ Analysis Data ‣ LapTimer* (or similar)

and send one or more to my email address Harry@gps-laptimer.de.

Thx.

I sent one. I didn't look at all of them, but the last few chronologically all looked the same.

I will check and come back. I plan to submit 22.1.0 tomorrow. In case it is an easy one to fix, I can add it.

Changing ECU's addressed in the OBD Tweaks section of Expert Settings from ALL to ECM seems to have fixed the issue.
