Hello.

We had problems with optic pickup, on logger it goes up and down, without any reasonable meaning. I think it messed up other curves too, because rear end curve was same looking.
I fixed that optic cable and it was ok.
After that, it worked couple rounds nicely, until problem came back.
Now there aint no rpm, rear end information at lastest logging.
Exhaust temps are ok.
We are using oil press, pump press and blower press, nozzle press aint in use.
But at that last logging, there was information of that nozzle press too.
Is it possible that Loggers memory dont erase everything and it finds some old information and writes that?

Sorry my bad english, I'm from Finland so its not my best spoken language.
Hope you understand our problem.
