Ok, I thought Id pre check my VVE table with some values before I went into sd open loop etc.

I added the SCALEDCORVE_ PID to my options.txt but it didnt show or work. I went back and added the SCALEDUNVE_M and it works fine.

Im wondering if the lack of an "M" suffix has anything to do with it? I put in the PID as copy and paste from the e38 discriptions file as below.

SCALEDCORVE_ [4] MAP Corrected VE (.)
SCALEDUNVE_M [4] VE Sum Uncorrected (.)

(Forget the bad calc pid, found a work around thanks to "5.7ute")
