Datalogging 10 bit stream

[Matt]

Maybe your voltage > AFR translation in the CSV file needs adjusting to be more accurate

Otherwise with the UEGO you can connect a USB>Serial converter to the serial line and feed it direct into Nistune (AEM UEGO section of this forum has the document posted)

[Matt]

Also what might help is to log your voltage into the Arduino as a separate channel

Aux2.csv for example make
AEM Volt
0,0
5120,5.12

See if the voltage matches up in Aux2 using a multimeter

You can also pipe the 10bin serial stream into python via COM-X, parse it into a Nistune Supported Wideband stream, and pipe out via another COM-Y. Then configure Nistune to use a sported Wideband and select COM-Y as the communications port.

See viewtopic.php?f=31&t=3549#top post from Fri Dec 29, 2017 9:03 pm to get the python module I wrote to test out nistune coms for plx devices.

If like me you have the nice idea to use Arduino Micro for wideband monitoring, because it's small and easy to hide in a car...
You will have to do this fix in order to get Nistune reading the serial reply.

Code: Select all

You can solve the DTR Problem by editing "Arduino\hardware\arduino\cores\arduino\CDC.cpp.
