bgt x15 need help

[Bengy88]

By imported do you mean imported to the us, imported to Australia, or some other country?

The @m*m^2 document hasn’t been updated to cover the x15 yet. It is something the author works on in his spare time and he just hasn’t made it that far yet…. The same logic can be applied to the cm2350 x15’s as the other engines if you know how to figure out safe timing and boost due to the extremely high compression….. and if you can sort through the other few thousand parameters that were added to them.
