A50 to A40 swap???!?

[rfinn04]

Heard about swapping the a50 tcm for the a40 tcm from the early lmm's. Is this just plug and play? Or do you have to program the lml and a40 to work together? Precautions??? Any help would be great!!!

I took a A40 from a 07.5 LMM and put it in a a 2010 that had a A50 worked exactly the same no flashing ect was needed and was able to tune it with no issues. Aslo put the A50 into the 07.5 LMM with no troubles.
