ADX to suit VS Kalmaker

[VX L67 Getrag]

I remember reading a fair while ago that with most kalmaker versions will log 90% correctly with the same factory code but just checking it is right?

I'm trying to fix up someone else's VS L67 3 bar map tune so W46 which is based off the CKUM file.

I think it may all log o.k. with the $51 adx & may just need to add the packet offset 0x31 & just use standard engine listen & get the right calculation, does that all sound feasible?
