How high can a Saab 9-3 go?

I've made a lot of progress in the last couple of days.

First, I found the Saab trouble code list that shows that if LTFT goes over 25, a CEL is thrown. So 25 is the upper limit for this car.

And I now know the relationship between LTFT and ethanol content. Is is y = 0.54x - 4.6. y is LTFT, x is ethanol content.

With these two pieces of info, I now know that I'll get a CEL at 54.8% ethanol!
