Simple question - How do I get a PID not to log, if it's outside the conditional? So IF(MAP<90) THEN don't log AFR. Something like that. I already know how to use math in HPTuners and I already know how to set up IF conditionals. The problem is, the conditional always returns 0 or 1 so it either zeroes the answer or it keeps it as whatever it is. This is no good because the scanner just averages all the zeroes with all the non-zero data and gives nonsense. Imagine seeing an AFR of 5.2 on your chart and being like WTF? That's what I get because it's averaging a bunch of 0s with stuff like 14.7. I just want to not record the values that are out of bounds. How do I do that?
