4 is current firing cylinder number #1, and the order is per brackets.
Sorry, I don't follow that, ( I do but ...)
Am I missing something or had the GM guys been smoking some weird S*** ?

As I can see so far,
4=cyl 1
5=cyl 4
6=cyl 6
7=cyl 7
8=cyl 8,3,5 or 2

This lines up with the banks of a 2 plane manifold, don't see how that would fit with anything here.


On the last log I had (Needs a Non Proprtional Font to view properly)

At Startup
Rpm 45 70 100 107 280 688 1063
Cyl Id 0 77 77 86 67 47 86 66 76 57 86 86 86 86 66 86 66 86 76 86 86 86 86 76 47 57 66 86 86 47
Cylinder 7 7 6 1 6 7 4 6 6 7 7 1 4 6 1

Consecutive logs idling
Cyl Id 86 86 86 86 47 86 77 47 86 86 47 57 86 86 57 67 86 86 67 77 86 67 86 86 67 86 77 47 86 86 86 86 77 47 86 86 47 57 86 47 86
Cylinder 1 7 1 1 4 4 6 6 7 6 6 7 1 7 1 1 4 1


Since I have no idea how many frames have been lost between each frame I've received, how would I tell which cylinders are represented by the 8x's
Why would the units column change if it doesn't represnt anything ?

Thanks
