Hi,

I am novice Pectel user.
Previously I have looked logged data several times from ECU, but suddenly there is no logged data anymore. Also the ECU clock seems not keep in time, It shows time like this 1#)3
I could get into ECU like before but datalog seems to be always empty also real time monitor don´t show anything.
What I have missed?

Best Regards
Miikka

Your internal battery will be flat/out of service. The ecu will loose logs and default to a base log file setting, will also loose time.   Needs to go to Cosworth for a service..  contact is Will Kerridge at Cottenham.

Thank You.
Can the internal battery to be checked from the log? Or does it have a recommend life cycle?
I have already send (5 month ago) one ECU to Cosworth to battery change and this need it now too. Symptons were slightly different.

Hi,     
        No, there is no internal battery log (that i know of) and the life can depend on a lot of factors, how long the ecu sits without power up, temperatures etc.  They usually last 5 years average, i have some that are probably 10 years old, i have some that have gone in about 3 or 4.    If the battery is almost gone, the system will loose the logs and time after being powered down for a time, either overnight or a few hours. If the battery is totally gone then it will loose the logs instantly on power down and will loose the date. Are you also loosing the logging setup and the system defaults back to the Cosworth base log setup? What version of firmware are you using and what EOT version?

Logging config is gone.
Firmware 3-17(6) and EOT 1.23 (build 72)

So battery is definitely gone. I guess it is totally dead so that is why different symptoms..  Need to send for replacement..
