I read what the problem is and the fix is to program full the first time, this is a A40 mod.
But I had already program cal this file last year and it went in fine.
Today I changed ECM tunes and wanted to just load the A40 mod in again, just because.
The ECM tune full went in fine today, then when I started over with the A40 mod program cal, I got this $054D.
I updated my Spade after the last update in December, maybe that's the issue explained doesn't support calibration changes.
I'm guessing I'll just need to use Program Full to load the A40 mod in again.
Then I'll only have to use program cal if I want to make A40 changes in the future.
Thanks, I'm confused myself reading this
