Review: Motordyne E370

MaDMaXX

This is why i posed it as a question, i'm not 100% sure how the uprev tune works, but in some tunes, only the altered values are loaded with a tune.

For example, and in this case, the suggestion i'm making, is that the SZ tune doesn't contain the spark advance change value, therefore, loading the SZ tune over the Church tune, results in the spark advance not changing.

This was the way my SCT tune on the Mustang worked, i'm questioning whether the uprev works the same way.
