Please share output table (voltage vs AFR) from manual so I can help.

HI,
I downloaded the datalog, but I always have the turbo pressure at 0.6, but on the utcomp display it works up to 1.6bar

How come ?
Thank you

I see in logs old data from 2023-11-26 and later from 2024-02-12. Seems like this is data with old setting and now datalogging is disabled. Please make sure that you have enabled data logging. If you are sure, please share me your utcomp settings file, I'll take a look.

hi Art, here is the utcomp data,
I had set manual recording, now I have set it to record every time I turn it on, is this correct? Thank you

I checked these settings and data logger is in manual mode (disabled by default). Just select in settings -> advanced -> datalogger recording when ignition swith is on and it will be working.

hi, I tried, it records everything except turbo pressure... I don't understand why.. other info, what sensor can I use to see the exhaust gas back pressure?

Have you updated your settings with parameters I have marked on screenshot below? In settings file you have shared data logger was disabled and recording boost pressure was also disabled.

I've never measured exhaust gas back pressure, first you will need to find out possible pressure range, and secondly you will need find pressure sensor for such range which will operate also in this temperature range

Yes

Now it's fine. Please share me your data logs file (.csv) from last 3 hours after settings were changed.
