    Subscribing for updates. I just read out my 2011 A50 24259875/24259876 file successfully and emailed it to support@efilive.com. Is there mapping/editing functionality in the works?

    is it known that a 09/10 k2500 calibration (say [24256581, 20759776]) works in 11+ LML k2500, or it definitely does not? since there is no 11+ edit support available yet...

    Pretty sure that is a no go. The ALLISOn changed in 2011 and added in a pressure control solenoid to control line pressure. By running an LMM tune, it will run max line pressure all the time. Somebody posted about this awhile back when they had to go back into a built LML and replace fried C5's and some other broken pieces because they put an LMM tune into an LML.

    how does EFIlive handle A50 hardware differences for full reflash? it does not seem to reflect any distinction between A50 and T14. the thing is that in some cases a VIN will use distinct operating systems (for A50 and T14) but the same trans calibration segment. so say i were to full flash into a T14 #24256861 a *ctz file read out of an A50 #25978353, will it work, or brick the T14, or...?

    EDIT: never mind, i understand.

    has anyone tried using a T14 with 09 LMM 2500 pickup code in an 06-08 2500 pickup? i know the reverse works (A40 in an 09). tia.

    EDIT: tested 09 LMM 2500 calibrated TCM in 08 LMM 2500, doesn't work.

    another question. has anyone used an A40 or A46/T14A calibrated with a 2500 pickup cal in a C4500/C5500 MD truck? i know values would need to be copied over to replicate the shift feel, etc. i just want to know if it works in general without intrinsic issues. iirc someone on diesel forum posted *something* about that but i wasn't paying attention to this subject at the time. thanks in advance.
