cm 871 incal updated AV's

[NewSon]

understood. but I need to figure out if the engine has been fooled around with a completely different cal , or it is actually a correct, updated cal that belongs to that particular engine. i saw a pdf doc once on the web, but i was stupid enough not to copy it for me. now, i have a struggle finding it.

it said something like:

old cal AV10045 cpl 3245

updated cal AV10234 cpl 3246(example)
