Hey.
I have a homemade wbo with the lc-1 protocol.
Does the logger support the wbo lc-1 protocol?
Is it possible to add it?

Try the Innovate Wideband AFR plugin.

I try it.But the readings are grossly understated.

What units of measure does your WBO2 send out?

The developer made the protocol lc-1.
In another program, the readings are correct.
The RR logger is understated. Is it possible to fix the plugin or add a new one.

The plugin has worked with Innovate devices for many many years without issues.
Can you send a rr_system.log with TRACE enabled so I can see what the controller is sending to RR Logger?

Okey i try it. Thanks.

Log-file.

Comparing the testimony revealed that underestimates exactly 3 times.

I looked through the log and I see the protocol follows Innovate's Serial Protocol Format Version 2.
What I find odd is that the multiplier in the second word equals 4.9. If you multiplier the lambda value in the third word by this you will get very low AFR values in the Logger. If this WBO2 is measuring petrol Air Fuel Ratio then the multiplier should be set to 14.7. Is this a value you configure in the setup of the WBO2 or is it hard coded?

The value does not change. There are no settings.

The multiplier needs to be set to 14.7 for gas, or 1 for lambda (λ), or another value depending on the fuel type you are using, I'm not sure what the 4.9 multiplier is for.
FYI:
AFR Ethonal: λ*9.0
AFR Diesel: λ*14.6
AFR Methonal: λ*6.4
AFR LPG: λ*15.5
AFR CNG: λ*17.2
AFR Hydrogen: λ*34

Normally this is set with the Innovate LM programmer after the WBO2 is installed.

Is it possible to fix the plugin to enter the value manually to correctly display the afr.?

As dschultz pointed out, the problem is likely incorrect Lambda/AFR setting which can be changed by running LM Programmer Software.

Here's the software https://www.innovatemotorsports.com/sup ... 3Setup.exe
Here's the manual for LC-1 https://www.innovatemotorsports.com/sup ... Manual.pdf

I have a WBO homemade Protocol written by the author developer and this ratio does not change through lm software.

If the developer created this WBO2 to utilize the Innovate protocol, then the correct multiplier needs to be sent in the data stream. I suggest you contact the developer to have them correct the multiplier value.

Changing the plugin to accept a user defined multiplier correction factor seems like an odd thing to do since the user wouldn't know what the correction factor would need to be set to. How would you calibrate the system to determine this?
It would be easier to have a setting to ignore the multiplier and use only the lambda value.

Another odd thing I noticed is that the values reported (although wrong) vary by a large amount within just a few milli-seconds. In this example you can see this.

Within 118 msecs the values changed from 4.802 down to 2.3912 and back up to 4.802.

If I use the lambda value sent (ignoring the multiplier) this is a swing from 1 down to 0.852 (or 14.7 AFR down to 12.52). This seems to be changing too fast and it happens quite often throughout the trace.

In the first video the WBO2 seems to read quite high at idle, well above 14.7, is the WBO2 calibration off?
