Don't know about the M6 conversion, but with my A4 to TH400 conversion and no speed sensor, I wasn't getting any timing at all (10* at WOT). It was forcing to the Park/Neutral tables even though the TPS was >0. Might wanna log it just to be sure you aren't getting the same problem. I've heard it is not so on M6's, but might be worth a few minutes to see.
