Analog Multiplexing issue

(1/2) > >>

Matus:
Hi,

I have analog multiplex connected inside ECU (done by order during ECU build) and all seems to be working in steady state. It is switching, sometimes it is like ECU takes few sec till it start switching analogs.  >> Engine stopped "noise "clearing out VIDEO >> https://youtu.be/vZWfPuv0T38


However It is really strange behavior with engine running, it seems to me like lack of speed or something .. result is useless analog inputs.   >> Engine running  VIDEO :https://youtu.be/htHuMvQeEzE

Firmware : 1.38

Anybody who made it ?

updated ini files in vemstune?

Matus:
Yea, I double check that. Also tried  version 1.41, still the same. Last time I test it was 4 days ago.

btw, in vemstune preferences you have to select enable compiled files NO, :) anyway as much as I have experienced that it works all good :) more then 20 multiplexers working

Matus:
Hmm, wasn't even aware about it :D. 

However, unchecked, config burned, nothing has changed.
I checked ini files before try, it download 4 new files but nothing has changed for me.
Also I tried to rollback to 1.38, still the same.

Any other idea what to check ?
I am considering if it takes maybe noise of the sparks or something, but it is not periodical, doing it even in idle and randomly ..
