GM Module timing curves

[1BadAction]

So we don't completely hijack the other thread.

There was some testing done on Thirdgen.org that proved even 2 differant numbered GM modules have differant timing curves. I furthered the testing and can guarantee that you never know what timing will be at any RPM with aftermarket modules...

So you're saying that 24 degrees commanded might not necessarily = 24 degrees? Is this why all these timing curves look weak on the "mechanical" side?

My 90kpa @2800RPM is 20 degrees in the tune, with no adders active, but it could actually be higher (or lower?)
