    My timing is around 22 but that is only on e30. I?m limited to about e40 on the stock fuel system. With just pump gas I can only run around 18 degrees of timing before I get some knock.

    I leaned mine out to .85 and seems to like it. For a few pulls it was .87 and seemed fine with that but not something I would do full time. Amazing how lean direct injection can run over port...

    Yes bump your lambda to .84 and see if it clears the knock. I was getting some knock at .82 and leaning it out a bit fixed that.

    Dont keep low octane timing the same as high. Good way to blow the motor up.

    10 degrees more timing is a lot even for E85. You need to watch out because its hard to get knock with E85 and you can damage the motor even with showing no knock.

    You are not scaling the injectors correctly for 1300cc
