I ran some Durametric work sessions for
cam shaft deviation and saw a change in deviation as the car warmed. Ahhhh have not seen this before and am properly freaked out! There were not fluctuating/dancing but they drifted. Pos.1 dev. drifted the most.
The files are attached; scroll through and have a look. The time stamp in the file names are indicative of first to last sessions and cold to warm.
I could see pos. 1 vary from -1.59 all the way to -2.05 degrees
and pos. 2 vary from -3.69 to -3.8 degrees. Session 3 file: 2014_09_29_22_03_20 shows a lot of change starting at line 489!
The readings eventually stabilized in the later sessions close to 86 C at: pos. 1>-2.05pos. 2>-3.8
Is this: a real
cam drive issue; a sensor issue; a normal senor warm up problem; Durametric sampling problem???
Edit: apologies the files are not permited; I will have to email them or cut and paste some of the data
