I just got my VE table dialed in (i think) and just started to try and dial the maf in via logging the "MAF-Short Term Fuel Trim" histogram. the problem is that when i go to log this, it says that this is an unsupported parameter. what am i doing wrong? ive searched but came up confused. i believe i need to set up a custom histogram but i dont know how.
the vehicle is a 2006 trailblazer ss with exhaust and intake. im very new at tuning and appreciate the help. thanks!
btw, using BBA's guide to tune,
