Last pass, we charged the battery and got the car really cooled down. Doug also took out some more fuel and for the last pass of the year, 15.085/ 89.88!

So are you still running the car in Open Loop? Correct me if I am wrong, but this seems to be the simplest way to change the fuel tune, leaving out many other parameters in closed loop?
