Busy day at work, sorry. I haven't done the M3 conversion yet, but someone that's on a stock bin might be best, just to rule any scaling/tuning issues out. Then again might need some adjustments to smooth anything out after.
Would be interesting to test it on varying degrees of M3 swapped parts, but as a start, someone that has blatant and easily repeatable shift issues and a minimal amount of parts swapped would be great. At this point though, anyone or everyone just to prove/disprove the viability.
