At 18:1 under load you would have 0 power.

Its possible the program isn't 100% accurate but its all I have :-(. The ecu is commanding 18 but the actual afr is around 11 and at redline its at 10.

Yup I disconnected the negative terminal and let it sit for about 15 minutes. I did this about 700 -1000 miles ago.
