I had the best day ever running in lean burn mode 18.5 to 19.0 A/F ratio.
Running a 10% ethanol blend premium fuel I got 64.8mpg.

The engine worked great and I still have some more testing with it running a 22:1 A/F ratio.

I reduced my mph down to 58mph due to the fact I know I won't get good results until I finish my aero-mods.

I did some testing at 22:1 A/F and the car did surge a bit. So I might be at my max A/F ratio?

Anyway time to celebrate!!!!!!!!!!!!!!!!!
