9r12 / 9r12c - what are the differences?

And where can I find the 9r12c file to d/l?
Is there a library for the most recent U7137 updates to be found?
NOT in the sticky from 2008.

My particular unit was delivered last week with 9r10 crom installed.

And one more question ...
How can I tell the production age (old gen vs new gen) of my 7137 unit is from the serial #?

9r12 is the final draft of the 9t12 test Croms. only the latest Crom is posted on the "Downloads" page.

no clue what differences there are between 9t12c and 9r12. probably similar, may even be identical.

I have copies of several U7137 Croms including 9t12a and 9t12c. PM me your e-mail addy if you want 9t12c.

your tuner should be new Gen. old Gen were U900 instead of U7137.

I thought that the 9t12c crom had a couple parameters that the release version does not yet have, such as ESP delete. However, I can't find ESP delete on the 9t12c crom and will be going back to the release version, if there is no benefit to the 9t12c over it.

I have a custom tune and the ESP delete is not in quick adjust, engine, or tranny adjustments...where is it 'supposed' t be?

Thanks.
