so I was doing some loging today and came across a couple spike in my iat log where it dropped to a really low number, kr went up alot, ltft1 whent sky high. Anyone wanna guess as to what caused these. Here is a screen shot.

computer problem

 

also it was black box logging if that matters but it happens 4 times in a 15min log.

 

looks like a lost frame of data to me.

 

Does a lost frame mean the PCM didn't actually see this spike?
